Most white fleshed peach cultivars lack good flesh firmness for whole- 

 sale distribution in New Jersey. The best white fleshed peach we have 

 evaluated is Summer Pearl^. The following white fleshed cultivars are 

 suggested for local market planting: 



EARLY WHITE GIANT (Garnet Beauty season) 



RARITAN ROSE (Jerseydawn season) 



EDEN (Redhaven season) 



REDROSE (Loring season) 



SUMMER PEARL^ (NJ 252 cultivar) (Cresthaven season) 



WHITE HALE OR MONEYDEW HALE (Jerseyqueen season) 



LATEROSE (Rio C sa Gem season) 



Most of the pe.ich cultivars recomme ided and suggested lave very accep- 

 table flavor. A few of our most flavo ful cultivars are Brighton (Garnet 

 Beauty season), Topaz (Norman season), Sunhigh (Loring season), Summer 

 Pearl^and Madison (Cresthaven season), and Laterose (Rio Oso Gem season). 



Reliance (Norman season), Enroy (Loring season), and Madisoi 

 (Cresthaven season) would be three peaches to try in areas where some peac i 

 cultivars cannot be cropped successfully because of low winter temperatures. 

 It is important to remember that the wood and bark of some peach trees will 

 be injured by low temperatures but still have a full crop of fruit buds. 



Detailed descriptions of many of these peach cultivars are contained in 

 Bulletin FS095--New Jersey Peach & Nectarine Var let ies--avai 1 able by writing 

 to me. 



POMOLOGICAL NOTE 



A Comparison of the Time of Ripening of Several Apple Cultivars

During the course of apple ripening the concentration of ethylene gas 

 in the core Increases many thousand fold. Monitoring the ethylene concen- 

 tration allows comparison of the time of ripening of different cultivars. 

 In 1985 fruit were harvested periodically from seven apple cultivars at the 

 Horticultural Research Center, Belchertown, MA. Ethylene data suggested 

 that at the Research Center Gala, Cortland, Redspur Delicious, Baldwin, 

 Spencer, and Mutsu fruit should be harvested on approximately September 17> 

 m, 19, October 5, 9, and 14, respectively. The actual dates of optimum 

 harvest would vary from orchard to orchard, but the relative times should be 

 simi lar.
