N. Y. Taxonomic and Host Range Studies With Pure-Lines of the 

 ( State ) More Important Plant Parasitic Nematodes Associated With Small 

 Fruit Diseases , (l) Develop techniques for obtaining and main- 

 taining pure- lines of plant parasitic nematodes; (2) obtain 

 pure- lines of important plant parasitic nematodes found on small 

 fruit crops; (3) maintain these pure- line populations at Geneva 

 and other institutions needing them; (A) learn range of variability 

 within pure-line populations; (5) compare range of variability 

 between several pure- line populations derived from populations 

 presently considered to represent a single species; (6) determine 

 host ranges of pure-line populations, with emphasis on physiological 

 differences that might exist within species,

N. C« Blueberry Breeding . To originate blueberry varieties for 



North Carolina and the Southeast, emphasizing: (l) very early 

 to midseason commercial varieties with improved fruit and plant 

 characters such as greater vigor and productiveness, better 

 adaptation to local conditons, resistance to diseases, and larger 

 bluer, better flavored fruit; (2) varieties ripening from very 

 early to very late for home use and local market for all sections 

 of the State; and (3) evaluation of various crosses for potential 

 value as sources of superior selections, and for information on 

 inheritance of economic characters to improve breeding.

Okla. The Improvement of Bramble Fruits by Breeding . To (l) 



secure varieties of promise and hybridize in attempts to produce 

 seedling for adaptation and resistance; (2) collect and maintain 

 a test planting of recommended varieties and evaluate newly 

 introduced ones; and (3) disseminate material which has indicated 

 desirable qualities.
