【Abstract】 The studies showed that there was severe crossing obstacle between Eruca sativa Mill and B.campestris and the number of hybrid seeds was related to the crossing patterns.It was observed that the distant-crossing ovary nearly stopped growing at eight days after pollination.Morphological evaluation of F₁ seeds were matroclinous hybrid in almost all cases.更多还原
