Abstract
Embryo abortion stage and rescue system of hybrids iwere studied in the distant hybridization between plum and apricot. Identification of the hybrids was also made. The results showed: Embryo abortion started from three weeks after pollination; The germination and growth of embryos were different at different growth stages, which could germinate and grow with PF value0.5, but can not with PF value0.5; In embryo rescue system of hybrids, the best germination and differentiation medium was MS + 6-BA 2 mg·L-1 + IAA 0.3 mg·L-1, the rate of germination and differentiation reached up to 80%, buds induction and multiplication medium was MS+ 6-BA 1.5 mg·L-1 + IAA 0.3 mg-L-1, rooting medium was 1/2 MS + IAA 0.8 mg·L-1. Some hybrids were transplanted into the field successfully; Leaf shape investigation and identification by S allele-specific PCR and RAPDs showed that the hybrids were true ones.
