摘　　要：紫泰S是以广粤S与矮紫S杂交,经6 a 12代系谱选择育成的籼型水稻温敏核不育系。该不育系具有植株矮壮、柱头长、柱头外露率高等优点,2015年通过安徽省技术鉴定。利用紫泰S配组育成的强优势杂交水稻组合紫两优1392于2021年通过安徽省农作物品种审定委员会审定。Zitai S, derived from the cross between Guangyue S and Aizi S, is an indica-type thermo-sensitive genic male sterile(TGMS) line in rice bred by pedigree selection of 12 generations over six years. With the advantages of short and strong plants, long stigma and high stigma exsertion rate, it passed the technical identification in Anhui Province in 2015. Ziliangyou 1392(Zitai S/R1392), a heterotic hybrid rice combination derived from Zitai S, was registered and released by Anhui Provincial Crop Variety Appraisal Committee in 2021.
