利用60 Co－γ射线照射光温敏核不育系广占63－4S的干种子，以诱发其突变，从中选育出了一个白化转绿突变体白S。该突变体在前2叶除叶尖外完全白化，第3叶部分白化，从第4叶开始白化的叶片转绿，后期恢复成白绿相间条纹色。与亲本广占63－4S相比，白S的株高较矮，叶片叶绿素含量较低，每穗颖花数较多，但其它农艺和经济性状、育性、自交结实率等均无显著差异。白S所配6个组合在单株理论产量方面的超标优势为－17．6％～21．9％，平均为0．7％。对生产上如何利用白S的白化转绿特性有效地提高水稻杂交种的纯度进行了探讨。

A new albinotic green-revertible rice mutant “Bai S” was bred from the photo-thermo-sensitive genic male sterile line Guangzhan 63-4S by using 60 Co-γray to irradiate its dry seeds .The first two leaves of Bai S were completely albinotic expect for leaf opex , and the third leaf was partially albinotic .The albinotic leaves of this mutant gradually became green when the fourth leaf fully emerged out , and they recovered to green-white stripe color in later period .In comparison with the wild-type parent Guan-gzhan 63-4S, Bai S had lower plant height, less chlorophyll content in leaf , and more glumous flowers per spike;but there were no significant differences in the other agronomic and economic traits , fertility, selfing seed setting rate and so on between Guangzhan 63-4S and Bai S.The over-standard heterosis of 6 combinations from Bai S in single-plant theoretical yield was -17.6%~21.9%, and its average value was 0.7%.The author discussed how to use the albinotic green-revertible feature of Bai S to effectively en-hance the purity of hybrid rice seeds in the practice .
