APPLES AND PEARS 



Breeding 



111. Inheritance and Breeding of ConanercleLlly Important 



Characters In the Applet To (1) develop commercial varie ties 

 with a higher level of disease resistance ewLapted to Illinois, 

 ripening at different seasons and suited to specific purposes; 

 and, (2) study the inheritance of characters. 

 Sort. 65-323 



Miss, Selection and Breeding of Pome Fruit Varieties , To 



select by testing for yield and adaptability euad to develop 

 by breeding, varieties of apples and pears that will be suit- 

 able for home and commercial orchards, local markets, euid 

 adapted to Mississippi, 

 Sort. HK-2 



N. J, Apple Breeding , To (l) develop early ripening, red, firm, 

 high q.uality, dual purpose varieties, and attractive, dessert 

 quality, dual piorpose varieties with a long storage life and 

 good hemdling properties; (2) use triploid and tetraploid 

 varieties in the breeding program if they possess desirable 

 combinations of characters not present in diploid varieties; 

 (3) use promising mutant material obtained from high energy 

 irradiation of apple material under project 366; (k) develop 

 acceptable commercial varieties throughout the ripening season 

 that are resistant to disease; and, (5) maintain, asseoible, 

 and evaluate apple varieties and selections,

N. J. Pear Breeding . To (l) develop commercially acceptable 



varieties of pears resistant to fire blight and other diseeuses; 

 (2) develop satisfactory method of artificial inoculation of 

 yoiing seedlings; (3) establish and evaluate pear varieties, 

 selections, and chance seedlings as potential germ plasm for 

 breeding program; and, (U) evailuate disease resistance, eB-pec- 

 ially to fire blight, among seedlings produced in connection 

 with this project and the clones assembled under Objective (3).

Oreg. Maintenance of a Repository for Germ Plasm of Pears and 



the Evaluation of a New Germ Plasm , To (1) receive potentially 

 valuable plant materials of pear species, etc, from primary 

 sources or regional introduction stations for propagation, main- 

 tenance and evaluation of germ plasm; (2) make available to 

 fruit breeders or other scientific personnel, propagations by 

 buds, scions, or grafter trees; and, (3) initiate program of 

 evaluating, cataloging, multiplying, and distributing intro- 

 duced types, varieties, and strains of pears.
