 AN ALL-TIME RECORD was set in Illinois in 1948 both for 
 
 /^ total yield of corn and yield per acre. The total yield of 550 
 
 JL. JL. million bushels exceeded the 1946 record high by 44 million 
 
 bushels. The average yield per acre was 61 bushels. 2 Illinois now shares 
 
 the national record that Iowa set in 1946. 
 
 PLAN OF THE TESTS 
 
 Number of hybrids and their sources. Two hundred eighty-nine 
 hybrids were grown on five regular test fields. Six single-cross and three 
 double-cross hybrids were grown on two special test fields which differed 
 in productivity. Fifty-seven companies and individuals and the Illinois 
 Station furnished seed for the tests (see pages 88-89). 
 
 Eighty-one hybrids were grown on each of the fields except at the 
 Dixon Springs Experiment Station, where 60 entries were planted on 
 the bottomland field and 11 entries on the upland field (Table 1, 
 page 60). 
 
 A representative of the Illinois Station took almost all the seed 
 for planting the test fields directly from the warehouses of the pro- 
 ducers entering the corn. A few producers delivered small quantities 
 to the Station. Seed of Illinois and U. S. hybrids in commercial produc- 
 tion was obtained from the producers of these hybrids and also from 
 the Illinois Crop Improvement Association. 
 
 Selection of entries. Each year seed corn producers are given an 
 opportunity to nominate hybrids for testing on the various fields. For 
 some fields the number of hybrids nominated is so great that they can-

 COOPERATORS: EARL and WEBSTER GEHRING, Knox county; JOHN B. RICE, Iroquois county; R. B. VANDE- 
 VEER, Farm Manager, Illinois Masonic Home Farm, Moultrie county. The DeKalb field in DeKalb county 
 is managed by the Illinois Station; FRANCIS HART is overseer. The Pope county fields at Robbs are parts of 
 the Dixon Springs Experiment Station of which R. J. WEBB is superintendent. (Because of crop failure on the 
 Alhambra field, no 1948 data are available.) 
 
 not all be tested. For instance, 149 hybrids were nominated this year 
 for testing on the Galesburg field. This situation poses the problem of 
 selecting entries. 
 
 The "lattice-square" design that was used in laying out the entries 
 on each field limits to 81 the number of entries that can be included. Of 
 these, six in 1948 were Station-produced, open-pedigree hybrids that 
 serve as standards, or checks, with which to compare the performance of 
 the other entries. The remaining 75 entries were chosen, for the most 
 part, because the seed is being produced in large quantities. A few hy- 
 brids, however, were tested to see if their field performance met the 
 requirements for certification. 
 
 To widen the number of entries tested, a new plan was tried in 1948. 
 Some of the hybrids that had ranked high for the three previous years 
 1945, 1946, and 1947 were omitted. These top-ranking hybrids are 
 given an honor position in the present report as "proven hybrids." 
 
 Soil characteristics of fields. The test fields were medium to high 
 in productivity, and each represents a soil type common to the region 
 where it is located. Each field was selected carefully for uniformity in 
 soil type, productivity, and drainage. 
 
 In 1948 the northern Illinois test was moved to DeKalb county. 
 The other tests were conducted on the same farms as in 1947. The ap- 
 proximate locations of the test fields are shown on the map on the inside 
 front cover. General information on soil characteristics and soil man- 
 agement is given in Table 2.

 Field-plot design. A 9 x 9 randomized, lattice-square field-plot 
 design with 5 replications was used on the DeKalb, Galesburg, Sheldon, 
 and Sullivan fields. Controlled, randomized block designs with 6 replica- 
 tions were used on the Dixon Springs bottomland and upland fields. 
 
 Method of planting. All test fields were planted by hand on land 
 prepared in the regular way for corn. Each plot consisted of 2 rows 
 10 hills long, except at DeKalb where the plots were only 9 hills long. 
 Three kernels were dropped in each hill except on the fields at Dixon 
 Springs, where only 2 kernels were planted.

 for imperfect stand was the following adjustment for missing hills :

 GROWING CONDITIONS 
 
 The 1948 growing season was, in general, an excellent one for corn 
 in Illinois. The cool, wet spring weather let up early in May, allowing 
 early planting. A well-distributed rainfall, bright sunny days, and no 
 excessively high temperatures combined to give corn near optimum 
 growing conditions thruout the summer. 
 
 All test fields, except the upland plot at Dixon Springs, were planted 
 in excellent seedbeds. The compactness of the soil on the upland field 
 and destruction of the seedlings by crows resulted in a poor stand there. 
 Germination was good on all fields but Sheldon, where a dry period 
 following planting reduced the stand. The corn planted at Alhambra 
 on May 27 was seriously damaged by the black cutworm, Agrotis ypsilon 
 (Ropt. ). The field was double-disked and replanted on June 18. A com- 
 bination of wet weather while the corn was young and the poor drain- 
 age characteristics of this field resulted in a crop failure. The 1947 
 results and three-year summary are therefore again presented for this 
 area. 
 
 In August there were scattered hail storms in the west north-central 
 area. The Galesburg field was not struck, but high winds accompanying 
 the storm caused considerable lodging. Sullivan was the only other plot 
 where lodging was of importance. 
 
 Warm, sunny days in the fall allowed the crop to mature before the 
 first general state-wide frost occurred on October 18. 
 
 INSECT PESTS 
 
 European corn borer. During 1948 none of the test fields were 
 located in areas where losses due to the European corn borer, Pyrausta 
 nubilalis (Hbn.) were important. Neither stalk breakage nor ear-drop- 
 ping because of borers was extensive enough anywhere to bring out any 
 differences in these hybrids to attack by this insect. 
 
1949] ILLINOIS TESTS OF CORN HYBRIDS: 1948 63 
 
 Corn rootworms. Corn rootworms, especially the southern corn 
 rootworm, Diabrotica duodecipunctata (F. ), were active in all test fields. 
 But weather caused lodging after rootworm attack on only two fields 
 Galesburg and Sullivan. 
 
 On the Galesburg field a midsummer windstorm caused particularly 
 severe lodging. Here, of the plants leaning 30 degrees or more, the aver- 
 age lodging was 63.9 percent (a difference of less than 22.8 percent 
 between any two entries is not significant) (Table 7). 
 
 A summary of the amount of lodging caused by rootworm in 13 
 hybrids tested in each of three years at Galesburg is given in Table 6. 
 Tho differences of less than 20.7 percent between entries leaning 30 de- 
 grees or more are not significant, there are large enough differences in a 
 number of instances to indicate that some hybrids are better able to 
 withstand rootworm attack than others. 
 
 On the Sullivan field conditions were less severe. Average lodging 
 of plants leaning 30 degrees or more was 26.7 percent; for those leaning 
 45 degrees or more, it was 3.8 percent (Table 11). But the damage 
 on this field was so spotted that the differences among the hybrids 
 cannot be said to have any significance. 
 
 DISEASE DAMAGE 1 
 
 Stalk rot diseases. In the latter part of August scattered plants 
 died from stalk rot in many cornfields in a large part of the state. The 
 percentage of diseased plants increased progressively until late fall. 
 From October 12 to November 11, 39.7 percent of the stalks were ob- 
 served to be infected with Diplodia zeae, 17.6 percent with Gibberella 
 zeae, and smaller percentages with Fusarium moniliforme, Nigrospora 
 oryzae, and Sclerotium bataticola. Specimens sent to the Station, to- 
 gether with complaints about lodging from McHenry, Whiteside, War- 
 ren, Pike, Jefferson, and White counties, indicated that all were caused 
 by Gibberella. Thus this fungus caused considerable damage even if, 
 on the average, it was not the most prevalent one. In a few fields lodging 
 resulted from Diplodia, but on the whole the corn stood up remarkably 
 well considering the widespread infections. 
 
 On the basis of studies made in 57 counties, the loss from all 'stalk 
 rots was estimated at 4.3 percent. 
 
 1 Estimates of losses are based in part on survey data obtained by G. H. BOEWE, 
 Assistant Plant Pathologist, Illinois State Natural History Survey. 
 
64 BULLETIN No. 531 {February, 
 
 Root rot. Seedling blight and root rot were of minor importance 
 in 1948. Plants killed prematurely by stalk rots often had a decayed root 
 system later in the season, but the decay was probably not caused by 
 parasitic organisms. 
 
 Smut. Loss from smut again, as during the last few years, was 
 low. It was estimated at only .4 percent. 
 
 Leaf diseases. A little Stewart's disease and Helmmthosporium 
 blight could be found in nearly every field in central and southern Illi- 
 nois, but the damage, if apy, was very slight. 
 
 Ear rots. Damage from ear rot was low except in some fields in 
 north-central and northern Illinois that were killed by frost when im- 
 mature. For instance, in a field in Boone county all the ears were re- 
 ported rotted. This rot was caused primarily by a combination of Hor- 
 modendrum and Nigrospora. The corn on all test fields had become 
 moderately mature before the first killing frost. Data on the causes of 
 kernel damage are given in Table 3. Data on the percent of kernel 
 damage in individual entries are given in the tables for the various fields. 
 Rot damage was low because the fall weather was generally dry. 
 
 Diplodia, Nigrospora, and Gibberella rots were more prevalent than 
 in 1947. Hormodendrum was much more prevalent than it had been for 
 many years, causing not only commercial damage to market corn but 
 also considerable damage in numerous seed-producing fields in the 
 northern third of the state. Physalospora rot, which looks very much like

 Kernels in top row (A) are sound and free from disease. The kernels in the other 
 rows show four diseases that were common in 1948: (B) Diplodia zeae; (C) Phy- 
 salospora zeae; (D) Nigrospora oryzae; (E) Hormodendrum sp. 
 
 Diplodia rot in the earlier stages, has occurred sporadically in Illinois 
 from time to time. This year it was very evident in the upland field at 
 Dixon Springs.

 MEASURING PERFORMANCE 
 
 The entries in the 1948 test are listed in the tables in the order of 
 their total yields. Those having the same total yield and no damaged 
 kernels are placed in order by percentage of erect plants. 
 
 Erect plants. The percentage of erect plants in each plot of each 
 entry on each field was estimated at the time of harvest. The ratings for 
 erect plants show how the percentage of erect plants for each hybrid com- 
 pared with the percentage of erect plants on the field as a whole. (Each 
 rating is obtained by dividi.ng the percentage of erect plants for that hybrid 
 by the percentage of erect plants on the field as a whole and multiplying 
 by 100.) 
 
 Lodging may have been due to rootworm damage, weak or rotted roots, 
 corn borer damage, stalk rots, or weak stalks. Stalks broken above the ear 
 were not considered lodged. 
 
 Yield of grain. To determine shelling percentage, all the ears from 
 one replicate of each entry were shelled. At Dixon Springs, however, because 
 it was not practicable to shell all the ears in a replication, the shelling per- 
 centage of all entries was assumed to be 80 percent. A sample of shelled corn 
 was taken from the Dixon Springs plots by hand-shelling 6 ears of each 
 entry in one replication. 
 
 From the shelled corn one sample was taken to determine the percentage 
 of moisture at harvest 1 and to determine the percentage of damaged kernels. 
 The percentage of damaged corn was determined according to the federal 
 grain standards. 
 
 The total acre-yield was calculated as shelled corn containing 15.5 
 percent moisture, the upper limit allowable in No. 2 corn. The total yield 
 thus obtained for three fields (Sullivan, Galesburg, and Sheldon) was ad- 
 justed according to the procedure outlined by Cochran for randomized lattice- 
 square designs. 2 The total yield of sound corn was computed by deducting 
 the amount of damaged corn from the total yield. 
 
 Each hybrid's rating for sound yield, expressed in terms of percentage, 
 is simply the ratio between the bushels of sound corn produced by the hybrid 
 and the average number of bushels of sound corn produced by all the entries 
 on the field. 
 
 Height of ear. Notes on comparative height of ear were taken at 
 harvest time. Each plot of each entry was placed in one of the five fol- 
 lowing categories: low, mid-low (midway between low and medium), 
 medium, mid-high (midway between medium and high), and high. Begin- 
 
 1 All moisture determinations were made with a Steinlite moisture tester.

 ning with low and continuing progressively to high, these terms were as- 
 signed numerical values from 1 to 5 to permit the averaging of the plots. 
 
 Oil and protein analysis. For the first time, a sample of each entry 
 on each field was sent to the Northern Research Laboratory at Peoria for 
 an analysis of the oil and the protein content of the grain. 
 
 Significance of yield differences. Too much confidence must not be 
 placed in the particular ranking of a hybrid in the following tables, for 
 chance has played a part in determining its position. Unaccountable vari- 
 ability in the soil and conditions on the field will cause differences in yield 
 that are not inherent in the hybrids themselves. 
 
 The part played by chance in the 1948 tests has been calculated for total 
 yield by the mathematical procedure known as "analysis of variance." In 
 each table there is stated the approximate difference which there must be 
 between any two entries in order for them to show a true inherent difference. 
 Unless two hybrids differ by at least this amount, there is no assurance that 
 one hybrid is inherently higher yielding than the other. 
 
 RESULTS OF TESTS 
 
 Detailed results of the tests on six regular test fields and the two 
 special soil-adaptation fields are given in Tables 4 to 14 on the following 
 pages. See also Table 3 on page 64 on ear-rot damage. 
 
 Readers are urged to keep in mind these two things when com- 
 paring the performance of hybrids on any one field: 
 
 1 . Small differences in yield do not necessarily indicate the 
 superiority of one hybrid over another. See each table for the 
 amount one hybrid must exceed another before it can be con- 
 sidered the better. 
 
 2. The Summary section of each table is the most important 
 part. At least three years' results are necessary to give a reason- 
 ably reliable picture of a hybrid's ability to perform under vary- 
 ing seasonal conditions.

 SOIL ADAPTATION TEST 
 
 For the past three years the same six single-cross and same three 
 double-cross hybrids have been tested at Urbana for their adaptation 
 to soils differing in fertility level. The three-year average and the 1948 
 yields are given in Table 14. 
 
 Soils. The two areas used for the tests are on the Agronomy 
 south farm and differ in productivity as a result of long-continued use 
 of different cropping systems. In the Southwest rotation a high state of 
 productivity has been maintained by a systematic rotation of corn, oats, 
 clover hay, and wheat with a red-clover catch crop. The South-Central 
 area has been depleted of fertility by a rotation of corn, corn, corn, and 
 soybeans. Both fields have received manure and phosphate. The pre- 
 dominating soil type on both fields is Sidell silt loam. 
 
 Season. The 1948 growing season at Urbana was very favor- 
 able. Planting and harvesting were carried out at the normal times. With 
 the exception of 3 weeks following planting, rainfall was well divided 
 and temperatures were neither excessively high nor low. The 1948 season, 
 like the 1946 one, was very favorable. The 1947 season was not favor- 
 able for maximum production. 
 
 1948 results. The average yield of all nine hybrids in the 1948 
 test at Urbana was higher than that for any previous year. The same 
 hybrids, Illinois 972-1 and Hy X O7, that demonstrated their ability 
 in 1947 to yield well under adverse conditions showed their ability to 
 give exceedingly high yields under favorable conditions in 1948. 
 
 Early-maturing hybrids were the lower yielding ones on both soil 
 levels. 
 
 Three-year averages. The rank of the hybrids in the three-year 
 summary does not differ from their rank in each of the three years. 
 Illinois 972-1 and the single crosses which include the inbreds of which 
 it is composed stand at the top in performance on both levels of fertility. 
 It seems significant that the single-cross Hy X O7 has had a better per- 
 formance record over the three-year period on both soil levels than any 
 of the other hybrids tested.

 SUMMARY 
 
 In 1948 two hundred eighty-nine hybrids were grown on five fields 
 in Illinois. Planting dates ranged from May 14 to May 26. Good stands 
 were obtained, except on the upland field at Dixon Springs and the 
 Sheldon field. The growing season was excellent for corn. 
 
 Results of the 1948 hybrid corn tests were briefly as follows: 
 
 1948 yields. The Galesburg field in west north-central Illinois 
 had the highest average yield, 111 bushels an acre. The average yields 
 per acre on the other test" fields were: Sullivan, 107 bushels; Sheldon, 
 105 bushels; DeKalb, 68 bushels; Dixon Springs bottomland, 65 bushels; 
 and Dixon Springs upland, 51 bushels. 
 
 The average yield for all hybrids was 92 bushels an acre. This is 31 
 bushels, or over 50 percent more, than the record 1948 state average of 
 61 bushels. 
 
 Three-year summaries, 1946-1948. The highest-yielding hybrids 
 in the three-year summaries are as follows : Northern Illinois 
 Crow 407, Illinois 751, Sieben S-340, Ferris F-ll, Super Crost F-138;

 south-central fields are : Northern Furr 67A, Sieben S-450, 
 Doubet D-l, Nichols 5A, DeKalb 609; West North-Central- 
 Pioneer 339, Pioneer 304, Doubet D-72, Kelly K-374, Holmes 
 Utility 39; East North-Central Pioneer 313B, Pioneer 304, Mor- 
 ton M-380, Frey 644, Pioneer 332; South-Central Doubet D-41, 
 Bear OK-40, Producers 1050, Pioneer 313B, and Crow 607. 
 
 Lodging. Lodging was of importance on only two fields : Gales- 
 burg, where it was 29 percent, and Sullivan, where it was 23 percent. 
 The southern corn rootworm and high winds were mainly responsible. 
 Other fields were outstanding in the uniform erectness of all varieties. 
 
1949] ILLINOIS TESTS OF CORN HYBRIDS: 1948 87 
 
 Corn borer injury. In 1948 there was little or no injury on the 
 test fields resulting from European corn borer. 
 
 Protein and oil contents. For the first time a sample of each 
 entry from each field was analyzed for protein and for oil. The average 
 protein content for all entries was 10.2 percent, and the average oil 
 content was 4.8 percent. Correlations were run between total yield and 
 protein content, and total yield and oil content on three fields: Sheldon, 
 Sullivan, and Galesburg. Neither the protein nor the oil showed a cor- 
 relation or mutual relationship to yield. 
 
 Rots, smut, and blight. Cornstalk rots were very prevalent dur- 
 ing the fall and caused lodging and immaturity in some fields, but in 
 general damage was light. Root rots, smut, and leaf blights were of little 
 importance. Ear rots were most severe on northern Illinois fields that 
 were frosted while the ears were immature. 
 
 Effect of soil-productivity level. For the third year six single 
 crosses and three double crosses were tested at Urbana on two fields 
 differing in productivity. The yield of the lowest-yielding hybrid on the 
 medium-productive soil was 62.6 bushels an acre. The yield of the 
 highest-yielding hybrid on the highly-productive soil was 146.7 bushels 
 an acre, representing a gain of 134 percent. 
 
 Illinois 972-1 was the highest-yielding hybrid on both levels of pro- 
 ductivity. Single crosses made from inbreds involved in the parentage of 
 Illinois 972-1 also yielded high. 
 
 The single-cross Hy X O7 was highest in yield on both soil levels, as 
 an average of three years. Only on the poorer soils was the yield of this 
 hybrid significantly above that of the double-cross Illinois 972-1. The 
 range in yield, as an average of the three years with the same nine 
 hybrids on the two soil levels, was from 50.0 bushels an acre to 123.2 
 bushels, this high yield being almost 2i/2 times the low yield. 
 
 The three-year average yield of all hybrids on the medium-productive 
 soil was 63 bushels; on the more-productive soil it was 112.1 bushels.
