In Spring, 1981, a similar randomized replicated Delicious 

 rootstock trial will be planted. Both Gardner and Bisbee strains 

 will be planted on M7A, M26, MMlll, M9/MM111, and M9/MM106 root- 

 stocks. Gardner and Bisbee on M7A and MMlll will be planted 16 

 and 14 feet apart in the row, and they will be planted 14 and 12 

 feet apart, respectively, on M26, M9/MM111, and M9/MM106. All 

 trees will be trained as staked free-standing trees to a slender 

 spindle system. Rogers Mcintosh and Cortland will be the pollen- 

 izers. Training and cross-sectional measurements will begin in 

 1981. 



As these plantings develop, it is intended that numerous eval 

 uations will be made, including the following: 



a. annual yields per tree 



b. each tree's production efficiency 



c. tree survival 



d. prevalence of rootstock suckering 



e. nutritional status of each tree, and fruit 



susceptibility to bitter pit 



f. fruit maturation (firmness, red color develop- 



ment, watercore, etc.) 



g. postharvest storage life and susceptibility 



to physiological disorders following Ca and 

 regular cold storage.

III. Fruit variety evaluation at the Horticultural Research Center . 

 James F. Anderson 



We are beginning a new phase in tree fruit evaluation at the 

 Horticultural Research Center. This has been made possible by the 

 removal of several of the original plantings made in 1964. Because 

 of space limitations very few new varieties or selections were 

 planted between 1965 and 1978. 



Most of the varieties and selections under test in these orig- 

 inal plantings have been reported on at past meetings and in earlier 

 reports. Two varieties that have not been reported earlier are 

 Akana (TOHOKU #3) and Magnolia Gold. Akana looks promising for 

 early September apple market and Magnolia Gold is an attractive, 

 good quality Golden Delicious type apple, that has been completely 

 russet free in our trials. 



Plantings of apple varieties in the past 2 years include a 

 number of strains of Red Delicious, Mcintosh and Cortland. Addi- 

 tional apple varieties will be set next spring.
