摘要
早世代稳定现象首先在水稻杂交育种过程中发现 ,该现象可以早世代固定杂种基因型 ,这为培育可以多代利用的杂交种 ,奠定了一定的基础。就现早世代稳定现象的历史、发展及应用前景作一论述。
Stability in early generation was first discovered in rice hybrid breeding, because it can fix genotype in early generation of hybrid, this probably made it real to cultivate a new kind of hybrid seed which could be planted for several generations. The history, development and utilized prospective was discussed in this study.
