Pa, The Genetics and Improvement of Alfalfa (Medicago Sativa 



L,) , To (l) determine best existing strains or varieties of 

 alfalfa for Pa,; (2) determine methods of testing to give most 

 reliable and consistent data for strain evaluation; (3) in- 

 vestigate environmental factors, diseases, and insects affecting 

 persistence and forage yield; (4) conduct genetic studies with 

 alfalfa and related species that may clarify origin of Medic ago 

 sativa and implement alfalfa breeding; and (5) develop superior 

 varieties for Pennsylvania,

S, Dak, The Genetics of Reaction of Alfalfa to Diseases of the 



B lacks t em Complex . To (l) learn genetic nature of- reaction to 

 foliar diseases represented by the blackstem complex, using 

 diploid alfalfa, and (2) originate and use' methods of breeding 

 so disease resistance may be incorporated into improved 

 alfalfa strains.

Va. Evaluation of Radiation Induced Mutations for Use in an 



Alfalfa Breeding Progranu (l) Evaluate mutants produced by 

 radiation in view of use in an alfalfa breeding program.

 mutations. (3) Learn frequency and types of mutations pro- 

 duced by radiation.

W. Va. Maintaining Profitaljle Stands of Alfalfa , To (l) evaluate 

 soil conditions and disease and insect damage on established 

 fields of alfalfa and relation to yield and longevity of 

 stand; (2) learn effect of placement and amount of nutrient 

 elements on establishaient, yield, and longevity of alfalfa 

 stands; and (3) learn effect^ of soil fungicides and insecticides 

 on establishment, yields, and longevity of alfalfa stands.
