FRUITS (general) 

 Breeding 



Ind* Improvement of Tree Fruits and Small Fruits by Breeding 

 for Disease Resistance, Quality, and Other Characters . To 

 (1) search for and evaluate disease resistance and other de- 

 sirable horticultural characters in tree fruit and small 

 fruit species; (2) learn genetic basis for important patho- 

 genecity and resistance factors in pathogens and hosts, and 

 genetic bases for other desirable horticult\n'al characters 

 \ised in breeding programs; (3) examine chromosomal condition 

 in breeding stocks and induce changes in nimibers where nec- 

 essary to effect improvement by interspecific hybridization 

 and polyploid breeding; and, (h) breed commercially desirable 

 tree and small fruit varieties thro\igh hybridization of de- 

 sirable germ plasm*

Ky. The Development of Nev Fruits Adapted to Kentucky . To 



develop fruit varieties adapted to Kentucky and superior in 

 quality, food value, and resistance to disease.

La* Production, Breeding and Handling of Tree and Small 



Fruits vith Particular Reference to Figs, Pears and Miscellane- 

 ous Fruits . To (1) assemble and evaluate existing varieties 

 in Louisiana; and, (2) improve these varieties through breed- 

 ing and test them on various markets for fresh and processed 

 fruits.

Minn. Radiation as a Tool in Horticultural Crop Breeding . To 

 (1) study mutagenic effectiveness of radiations upon several 

 finiit and vegetable plants vith respect to dosage, conditions, 

 and time of radiation, and in relation to periods of growth, 

 dormancy, and rest periods of plants and seeds; (2) study 

 effects of radiations on subsequent developjoent of plants and 

 seeds; and, (3) produce mutations useful to fruit and vegetable
