利用普通野生稻与栽培稻杂交改良栽培稻品种的工作,由于野生稻不良的野生性状的影响,以及对这些性状的传递状况缺乏透彻的了解,致使栽野杂交育种收效较小。近年来,我们通过栽野杂交和顶交,调查与杂种后代选育关系较密切的9个性状在后代的表现,获得了一些可供育种工作参考的资料。 Utilizing the cross between common wild rice and cultivated rice to improve cultivated rice varieties results in less effective breeding by cross-breeding because of the poor wild characters of wild rice and their lack of thorough understanding of the transmission of these traits. In recent years, we investigated the performance of nine traits, which are closely related to the breeding of hybrid offspring, in offspring through planting and crossbreeding and top diplomacy, and obtained some references for breeding work.
