乔纳金是世界上许多地区形成商品化规模生产的少数品种之一,由于乔纳金被介绍只不过是二十年前的事,所以尚未达到生产高峰,不过正在迅速增加,将来具有很大的生产潜力。乔纳金是由康奈尔大学的纽约州立农业试验站育成并发表的,1943年在果园中对金冠树上的花进行去雄,并对其柱头授以红玉的花粉。1946年,把这个杂交组合的52株自根实生苗定植在第一试验园中。1953年,这批实生苗的有些植株首次结果,其中有一株产生了显著优异的果实,便被选出作进一步的评价。当时确定编号为:N.Y.43013—1。 Jonathan is one of the few breeds that have been commercialized on a large scale in many parts of the world. Since Jonathan was introduced only two decades ago, he has not reached the peak of production yet is rapidly increasing and will have a great future Production potential. Jonathan was born and published at Cornell’s New York State Agricultural Experiment Station. In 1943, the orchard was dusted with flowers on the Golden Crown tree and ruby ​​pollen was stigmatized. In 1946, 52 self-rooted seedlings of this hybrid combination were planted in the first experimental garden. In 1953, the first results of some of these seedlings, one of which produced significantly superior fruits, were selected for further evaluation. Was identified as: N.Y.43013-1.
