Title: Studies on Outcrossing Characteristics of Rice Male Sterile Line C815S
Abstract: The outcrossing characteristics of rice male sterile line C815S were studied,the results indicated that C815S went into full flowering stage on the 2nd~6th day after heading.The peak of anthesis time was from 9:30 to 12:00.The anthesis rate reached 76.7% before noon.The flower-opening duration of C815S was longer than that of CK.The stigma vitality was at strong level for 6 days,the rate of protrusive stigma was 90.5%,and the rate of wrapped grains was 4.6%.C815S was more sensitive to application of 920than CK,and the best dosage of920for the relieving of neck-wrapping was15.0~20.0 g/667 m2.The outcrossing seed setting capacity of C815S hybridized by different male parents in seed production was higher than that of Peiai 64S,and the yield in seed production was higher.
