| Abstract: | combinations of two-line indica or japonica hybrid rice were bred. The safety and high-yielding technique of seed production in Anhui had been studied. The results showed that the safety technique included four aspects: to select the practical P(T) GMS lines with stability sterile and lower sterile temperture; to arrange the photo(thermo)-sensitive stage of P(T)GMS lines in a safe period; to select the best heading and flowering stage of the male and female parents and to prevent the P(T)GMS lines from self-crossing for the ensure of the hybrid seed purity. That also introduced the high-yielding technique of two-line hybrid rice seed production for the development of seed industrialization |
