| Abstract: | 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. |
