Combining Ability's Analysis of Main Agronomic Traits for Six Two-line indica Sterile Lines
摘要
Abstract
[Objective] To discuss the breeding value of 6 two-line indica sterile lines through analyzing combining ability and heritability.[Method] 36 F1,originated from 6 sterile lines and 6 restorer lines with incomplete diallel design (NCⅡ), were used to analyze the combining ability and heritability of 8 agronomic traits.[Result]There were significant difference among the 6 sterile lines in all traits because general combining ability(GCA) variance reached significant difference at 5% or 1% level.WA918S was an ideal sterile line to breed high-yield combinations.On the other hand, utilization of higher GCA such as Xiner S or higher special combining ability(SCA) as Guangmo S and 1892S could also obtain high-yield combinations.[Conclusion] The results provide theoretical support effectively for utilizing these sterile lines.关键词
