Interspecific hybridization is considered to be an important driving force in the evolution, diversification, and formation of plant species. We selected one flowering Chinese cabbage variety and three Chinese kale varieties to make hybrids. Heterologous haploid offspring were obtained by embryo rescue and heterologous diploids were obtained by colchicine doubling. A total of 108 individuals of the F2, F3 and F4 generations from three parental combinations were investigated for field traits and SSR (simple sequence repeats) markers. The results showed trait separation and the appearance and disappearance of SSR bands in the hybrids, showing significant differences among parental combinations and among the different generations. This proved that the phenotypes of the initial generations of allopolyploids were not stable. This study not only enriches the genetic resources available for breeding flowering Chinese cabbage and Chinese kale, but lays a theoretical foundation for exploring the segregation of traits in distant hybrids and in different generations.

The objective of this study was the reproductive characterization of Capsicum accessions as well as of interspecific hybrids, based on pollen viability. Hybrids were obtained between Capsicum species. Pollen viability was high in most accessions, indicating that meiosis is normal, resulting in viable pollen grains. The pollen viability of species C. pubescens was the lowest (27 %). The interspecific hybrids had varying degrees of pollen viability, from fertile combinations (C. chinense x C. frutescens and C. annuum x C. baccatum) to male sterile combinations. Pollen viability also varied within the hybrid combination according to accessions used in the cross. Results indicate that male sterility is one of the incompatibility barriers among Capsicum species since hybrids can be established, but may be male sterile.
