| Abstract: | Objective] To study the breeding process,combinations′ performance and its use in production of Feng 39S.Method] Feng 39S was a dual-purpose genic male sterile line that derived from Guangzhan 63S treated with ion beam mutation after 5 years of 7 generations of breeding and selection.Its morphological characteristics,fertility conversion rule,combinations performance and seed reproduction techniques were studied.Result] Feng 39S shows the characteristics of low sterility-inducing temperature,desirable agronomic characters,good grain quality,wide compatibility,high out-crossing rate,strong combining ability and so on.In 2006,it was certified by Anhui Provincial Crop Variety Appraisal Committee.It has been matching a series of high yield and high quality hybrid rice combinations,some of them had been certified by national or provincial standards.Conclusion] Feng 39S is an excellent dual-purpose genic male sterile line with better group performance,and has great application prospects. |
