Abstract
. The results of studies on the development of a method for induction of growth and the formation of apomictic seeds of a cucumber seed (Cucumis sativus L.) are presented. It was established that the initiation of growth of apomictic seeds the reaction of the linear genotype of a cucumber has a significant effect. Three valuable lines of parthenocarpic type for breeding purposes have been singled out, in which, within 2 years (2016-2017), it was possible to consistently obtain fully-made apomictic seeds with high seeding qualities at a level of 84-92 % when germinated in potted seedlings. It has been established that the apomictic method of reproduction is considerably inferior (by 12-22 times) to the traditional method of reproduction, based on the inbreeding of linear material, according to the number of seeds formed. Nevertheless, for breeding goals the value of apomictic seeds is much higher, because the plants grown from them are the potential diploid homozygotes.
