| Abstract: | Peiza-feng2 is a new two-line temperature-sensitive type hybrid combination with high yielding and high resistance to disease , which was bred through cross breeding between the Dual-purpose mala sterile line Peiai 64S as female parent and restorer R0245 with fine grain quality as male parent. It was characterized by high yield, high resistance to rice blast, fine grain quality, moderate growth duration and easy seed production. The breeding procedure, characteristics, major techniques of cultivation and hybrid seed production of Peiza-feng2 were introduced in this paper. It was registered and released for commercial production in Guangdong province in December, 2006. |
