| 摘 要： | 通过农垦５８Ｓ／激光４号／／献党转育成的湖农５Ｓ，经研究属于籼型光敏核不育系。该不育系的主要特点是：不育起点温度低，达到了粳型光敏核不育系Ｎ５０８８Ｓ的水平，制种安全可靠；转为可育的临界光长要求比Ｎ５０８８Ｓ更短，在湖北不能繁殖，需在低纬度地区冬季繁殖；它柱头外露率高，开花习性较好，有利制种；配合力强，其杂种米质好，抗性较强，可以这配出强优势组合。

| Abstract: | A new photoperiod-sensitive genic male sterile line in rice Huncog 5S was selected and bredfrom Nongken 58s/Laser 4//Xian Dang. Studies showed that Hunong 5S belongs to PGMS lines of indica ricewith a low critical sterile temperature points (LPr)approaching to the standard of PGMS lines of japonica rice , it issafe and reliable for hybrid production. This line needs shorter day -length conditions during the fertility-transitionand it is incaple of selfing in Hubei Province but it can self in low latitude regions in winter . The high stigma exser-tion ration , good characteristics of bossoming are benifit to hybrid production. It has high conabining ability, Whichare good for selccting the crosses with heterosis |
