Embryological studies of reciprocal crosses between vicia faba and vicia narbonensis

摘要

A study was undertaken to asses the reciprocal crossability between vicia faba and vicia narbonensis. Flower buds or only ovaries of several varieties and genotypes were cross-pollinated in vivo(green house and field) and in vitro. Only few pollen tubes passed the style and entered into the ovary. On the whole number of 5320 cross pollinated in vivo and in vitro flowers and ovaries of vicia narbonensis only 78 globular hybrid embryos were observed. After cross pollinated in vivo and in vitro 3860 flower buds and ovaries of vicia faba globular embryos developed in 124 ovules.
