the major objective of seedless grape breeding program is production of grapes with high quality. breeding of seedless grapes is difficult because the embryos are aborted after fertilization. embryo rescue technique is utilized to obtain plants from crosses between seedless cultivars. in the present study, the effect of paternal genotypes and different iaa concentrations in presence of ba appli...

embryo culture were used to produce inter specific walnut hybrid plants between juglans nigra l. and j. regia l. developed ovaries were collected from j. rejia female flowers which were pollinated with j. nigra pollen grain by high dusting on a mature tree. in order to isolate embryos, exocarps were aseptically removed. isolated embryos from ovules at different developmental stages were transfe...

In this paper, interspecific crosses among Crambe abyssinica, Crambe hispanica, and Crambe kralikii were reported. In the C. hispanica x C. abyssinica (H x A) cross, 118 F1 hybrids were produced without embryo rescue, while 5 F1 hybrids were obtained with embryo rescue, when C. hispanica was used as the female parent. In the reciprocal cross (A x H), 232 hybrids were obtained without embryo res...

Intergeneric hybridization was performed between Moricandia arvensis and four inbred lines of Brassica rapa following embryo rescue. Three F(1) hybrid plants were developed from three cross combinations of M. arvensis × B. rapa, and amphidiploids were synthesized by colchicine treatment. Six BC(1) plants were generated from a single cross combination of amphidipolid × B. rapa 'Ko1-303' through ...
