Evaluating Insect Resistance in Varieties and Strains 
of Onion. To a) segregate varieties and strains of onion 
which are less susceptible to onion thrips and to onion 
maggot; and (2) develop a variety or varieties of onion 
which combiue insect resistance with desirable horticultural 
qualities.

rovement of e and Disease and Insect Resistance 
in Southern Peas (Vigna Sinensis) Throu Breeding. To 
develop productive varieties 0 uthern peas with improved 
qualities for processing and fresh market and to incorporate 
into these a resistance to Fusarium wilt, powdery miidew, 
bacterial blight, and nematodes. A total of 355 lots of seed 
of the genus Vigna has been collected, including 280 foreign 
introductions and 75 varieties of Vigna sinensis. These will 
be observed and classified as to mature seed characteristics. 
Greenhouse and field studies will be conducted to determine 
adaptability, productivity and insect and disease resistance. 
Using selected plants that are desirable as parental material, 
it is planned by hybridization and selection, to develop 
varieties with the characteristics stated above. Selected 
lines that are considered worthy of extensive testing will 
be included in trials at the S. E. Georgia Branch Experiment 
Station, Midville, Georgia, in cooperation with the 
Horticulturist of the Branch Stations.
