Nebr. Selection, Breeding, and Testing of Soybeans for Pro- 



ductivity, High Oil and Protein Content for Industrial and 

 Farm Utilization" ! To (1) conduct uniform tests of U. S. 

 Regional Soybean Lab. designed especially to improve & test 

 varieties for industrial uses & (2) determine effects of 

 differences of soil & other environmental influences, in- 

 cluding diseases, on yield & composition of soybeans — includ- 

 ing improvement & testing of varieties for home use as feed 

 & food.

Nebr. Evaluation of Effects of Radiations on Quantitative Char- 



acters in Soybeans as Related to Breeding Improved Varieties . 



(1) Evaluate genetic variability induced in the quantitative 

 characters yield, plant height, maturity, oil content, & pro- 

 tein content. (2) Predict genetic gain to be expected from 

 selection within a population derived from irradiated seed 



as compared to selection in a control population. (3) Ob- 

 serve irradiated populations in all generations & isolate 

 promising genotypes.

N. C. Riboflavin Content of Soybeans and Cowpeas. — A. Growth 



Stimulant(s) Associated with Riboflavin in Soybeans . To (1) 

 find why rat-growth bioassay for riboflavin in soybeans yields 

 values approximately twice those obtained by the photofluoro- 

 metric method, and (2) isolate and determine the nature of 

 interfering substances.

N. C. The Investigation of Genetic Variability of Soybeans and 



the Effect of Various Characters on Yield and Chemical Composi- 

 tion . To (1) estimate for the various characters of soybeans, 

 (a) magnitude of genetic variability &. changes in variability 

 resulting from selection, (b) nature & magnitude of interactions 

 between genotypes & environment, (c) expected genetic advance 

 due to different degrees of selection, & (d) genetic correla- 

 tions; (2) develop breeding procedures to make maari mum use of 

 genetic variability; & (3) obtain information on relative im- 

 portance of various characters on yield.

N, C. The Breeding of Grain-Type Soybean Strains that are Superior 



to Existing Varieties in Agronomic Characters and Possess Re- 

 sistance to the Common Diseases . To (1) develop soybean strains 

 that are resistant to shattering & lodging & that produce high 

 yield of good quality seed that are high in oil & protein; & 



(2) study inheritance of resistance to certain diseases & to 

 transfer resistance to these diseases & resistance to bacterial 

 pustule to strains possessing good agronomic characters.
