Iowa Development of Superior Sovbeaji Strains . To (l) develop 



new soybeatn varieties adapted to the various climatic and 

 edaphic conditions in Iowa and superior to those now grown in 

 respect to yield and other agronomic characters, in chemical 

 composition, and in resistance to the major diseases, (2) 

 cooperate with Regional Soybean Laboratory, FCRB-ARS, USDA, 

 in regional testing of soybean varieties developed in other 

 states in this region, (3) determine value of different 

 breeding methods in soybean improvement and to develop more 

 effective methods of selection, (4) obtain basic data on the 

 inheritance of and nature of gene action conditioning the 

 expression of agronomic characters, chemical composition, and 

 disease resistance, (5) determine the nature of host-parasite 

 relationships for each of the major soybean diseases, (6) 

 evaluate the disease reaction of breeding material developed 

 in this program and such other sources of germ plasm as may 

 be of potential value in soybean improvement, and (?) determine 

 factors that influence the development of soybean diseases 

 including mode of transmission and establishment in the host 

 and the effect of environmental factors on establishment and 

 development of the disease infection.

Mo. Improvement of the Missouri Soybean Crop , (l) Secure 



information on performance of new strains of soybeans in 

 comparison with stsmdard varieties in various parts of state. 



(2) Develop varieties with improved agronomic and chemical 

 characteristics and with improved resistance to disease. 



(3) Secure information on effect of date of planting, rate of 

 planting, etc., on performance of new and standard varieties; 



(4) certain questions of importance in breeding and production 

 of soybeans.
