The flavor is slightly tart when firm ripe, becoming mild when soft ripe.Fruit hang well
and the firmness is good, making this selection suitable for commercial production.
NJA114 (Jerseycot x NJA93)
A large apricot ripening with Harcot.This selection tends to bloom later than most of our other
apricot selections, including Jerseycot.Fruit are round-oblong, slightly compressed, 5.5 to
6.0 cm (2.2 to 2.4 inches).The fruit are orange with no blush.The flavor is generally mild but
it has been tart in a couple of years.Fruit have good firmness, making this selection suitable for
commercial production.
NJA82 (I13-36 x NJA11)
A large apricot ripening with Harcot.This selection is one of the earliest blooming apricots in
our collection, yet it often sets at least a light crop, suggesting that it may possess some
tolerance to spring frosts.Fruit are oblong, slightly compressed, 4.5 to 5.5 cm (1.8 to
2.2 inches).The fruit have a 5-40% red blush over an orange ground color with a slightly green
suture in some years.The fruit are tart when firm ripe, but the flesh becomes very sweet when
the fruit are soft ripe with soluble solids in the range of 16-21%.
A86-83, A86-86, and A86-105 (Glabrousapricots)
Tom Foley of North American Fruit Explorers (NAFEX) provided us with open pollinated (OP)
seed of an apricot cultivar called John Bonn Small from Door County, WI.He reported that this
strain is cold hardy, self-fertile, and quite inbred.From this OP seed we obtained three glabrous
apricots that completely lacked pubescence.We have been using these selections in our
breeding program but at this time we do not know the mode of inheritance of the glabrous
character.
SUMMARY
The focus of the NJAES tree fruit breeding program has been the development of productive
commercial tree fruit cultivars with superior fruit quality and improved disease resistance.
Because of the renewed interest in growing white-fleshed peaches and other novel stone fruit,
our program has intensified its efforts to develop white peaches and nectarines for shipping,
peen tao or doughnut peaches, and apricots.Several new cultivars are now available and in the
next few years the number will be increasing.Tree fruit breeding is a long-term endeavor
usually requiring at least 15 years between the time when the cross is first made and when the
new variety can be recommended for release.Our program has been aggressively producing the
next generation of seedlings which will provide improved varieties into the coming century.
The objectives of the breeding program continue to evolve to better satisfy the future needs of
the fruit industry and society.
