Various efficiency of new initial material use of the descendents of Japanese flowering crab apple (Malus) and domestic plum in breeding process on reducing the duration of juvenile stage has been distinguished: 88-22/11, 84-125/39 (Fi BM41497), Antor, Imrus, Kaunis, Kovalenkovskoye, Mechta, Redfree, Syabryna, Haralson, Charavnitsa and Empire. At including in hybridization domestic apple varieties and descendents from M.xfloribunda 821 the duration of juvenile stage at apple seedlings increases with each generation. The following crossing combinations, starting fruiting on the 6-7th year, appeared to be the most effective for seedlings output: 88-22/11 x Haralson and 88-22/11 x Empire. The character of trait inheritance by generation varied from intermediate inheritance to positive superdominance. Separation of transgressive genotypes was marked at combination Antor x Imrus where the frequency of transgression was 13%. As donors of early ripening the following variety samples were distinguished: 88-22/11 (BM41497 x Rubinovoye Duki) x Imrus. In course of the study there was analyzed the inheritance of duration of juvenile stage in apple hybrid progeny.
