长粒中粳稻两系不育系嘉1S的选育与应用
Breeding and Application of Long-grain Medium Japonica Rice PTGMS Line Jia 1S
摘要
Abstract
Jia 1S,derived from the cross between the photoperiod-thermo-sensitive genic male sterile(PTGMS)japonica rice line Habo 1S as the female parent and the long-grain japonica rice line B8 with fine grain quality as the male parent and followed selfing for eight generations,is a new PTGMS japonica rice line developed by the Jiaxing Academy of Agricultural Sciences and Zhejiang University.It was technically certified by the Zhejiang Provincial Crop Variety Appraisal Committee in 2022.Jia 1S has the advantages of low critical sterility-inducing temperature,early maturity,fine grain quality,rice blast resistance,medium outcrossing rate and good combining ability.It is suitable for developing early-maturing indica-japonica hybrid rice combinations.The hybrid combination Zhedajialiangyou 610 was approved by the National Crop Variety Appraisal Committee in 2023.关键词
