The transformation lasted for 7 days. The light duration for sensitization was 13 hours and 22 minutes. The stable period was as long as 57 days. The rice completed transformation from sterility into fertility in September 16, and the transformation lasted for,17 days. The light duration for sensitization was 13 hours and 9 minutes. The transformation was also correlated with temperature. Eight sterile lines of indica type have been transferred. Their sterile period was from early June to middle or late September. As their type was different ,their transformation was early or late. All the sterile lines showed good characters, and their seed production may be conducted in the early, middle or late展开更多
