Abstract: The new hybrids Eliangyou 78 is crossed by male sterile Enong 1S with the restorer R78 which has good performance in grain quality and blast resistance, but this male sterile has the bad flower habit and smaller angle of glume opening when encountered to high temperature, this made it has difficult in seeds production. According to the characteristics of the outbreeding rate of the female parent to be affected by the high temperature, a set of technical routes suitable for high yield seed production of this combination to avoid heat late sowing were summarized to provide a reference for this combination of seed production.

Key words: hybrid rice, Eliangyou 78, high yield, seeds production technology
