摘　　要：矮秆水稻江苏矮对赤霉素的敏感性及其矮生性的遗传分析钱前朱旭东张小惠曾大力严学强熊振民钱前：男，３３岁，博士，副研究员。本研究为浙江省自然科学基金资助项目。收稿日期：１９９５－１１－３０（中国水稻研究所，杭州３１０００６）关键词：水稻；矮秆突变体；遗传...A dwarf mutant Jiangsuai was found from the rice variety Guihuahuang of normal plant height.The genetic analysis was carried out by using the cross combinations of Jiangsuai with tall or semidwarf varieties.The height of F 1 and F 2 plants indicated that the dwarfness of Jiangsuai was controlled by a single recessive gene which was non allelic with dwarfing genes sd1 and sds(t),and was temporarily named dj(t).Further study was done on the sensitivity of Jiangsuai to gibberellic acid(GA 3) and Multi Effects Triazole(MET).Jiangsuai had the strongest response in the treatment of GA 3,its sensitivity arose to 365 6%-466 9%.On the other hand ,Jiangsuai was not sensitive to MET treatment .It is supposed that Jiangsuai is deficient in gibberellic like substances.
