温敏核不育系株1S是育种上广泛应用的优良早籼型水稻不育系，1999年通过湖南省品种审定委员会审定。自审定以来，以其为母本所配组合在湖南省区域试验早稻组中占有很大的比重。一大批组合通过审定，并在湖南省及南方各省区得到大面积推广，产生了良好的经济、社会和生态效益。本文通过对历年湖南省区域试验中株1S系列组合信息的收集和整理，对其产量性状、农艺性状等进行了相关分析，为选育高产优质的理想株型品种和合理的栽培措施提供参考依据和理论支撑。早中熟品种产量与米质、感病性显著负相关。

Zhu 1S is an early indica thermo-sensitive genic male sterile(TGMS) rice line widely used in hybrid rice breeding. It was released by the Hunan Variety Approval Committee in 1999. Since its approval, Zhu1S combination occupies a large proportion in Hunan province regional test in early rice group. A large number of Zhu 1S combinations were registered and widely extended in Hu-nan and other southern provinces, and have been achieving great economic, social and ecological benefits. Based on the information collecting and sorting with Zhu 1S combinations in Hunan province regional test,the relationship between agronomic characteristics and yield were analysed in the paper in order to provide some references for breeding and cultivating high yield and good quality rice. It showed the yields of early and middle maturity varieties was significant negative correlation to rice quality and disease suscep-tible compared to late maturty varieties.
