Interspecific Crossing and Embryo Rescue of the Albino Hybrids of Zantedeschia spp.
The cultivars of colored Zantedeschia hybrid: Ym035, Ym005, Ym088, Ym002,Ym064 and Zantedeschia aethiopica were used as the experimental materials. The setting rate of seeds was analyzed to find the best crossing combinations. Albino hybrids between Z. aethiopica and colored Z. hybrid were obtained by embryo rescue.Four different media were designed to explore the best one for embryo rescue. The results showed: the colored Z.hybrid was better as female parent than Z. aethiopica, and the best crossing combination was Ym002 × Z. aethiopic.Z. aethiopic planted in the ground was more vigorous than that planted in the pots. For the crossings in the Aestivae section, the combination of Ym005 × Ym035 had a higher affinity. MS+6-BA 1.0 mg/L+NAA 0.1 mg/L was the best media for embryo rescue of the albino hybrids from intersection hybridization.
