水稻半矮秆突变系Tad－M－1的遗传分析

Genetic Analysis of Rice Semidwarf Mutant Tad-M-1

分析了高秆籼稻Ｔａｄｕｋａｎ的突变系Ｔａｄ－Ｍ－１半矮秆性状的遗传．结果表明：Ｔａｄ－Ｍ－１半矮秆性状受１对隐性主效基因控制，该基因与矮脚南特ｓｄ－１基因和新桂矮ｓｄ－ｇ基因非等位，而与云南矮秆粳稻雪禾矮早的矮秆基因以及四川半矮秆籼稻一支腊的半矮秆基因等位．本文还评价了Ｔｅｄ－Ｍ－１的育种利用价值．

This paper dealed with the inheritance of the rice semidwarf of Tad-M-,a mutant line bred from traditional indica rice Variety Tadukan by radiation. The results indicated that semidwarf of Tad-M-1 was controlled by one pair of recessive gene, which was nonallelic to sd-1 gene of variety Aijiaonante and sd-g gene of variety Xinguiai and allelic to the semidwarf gene of Yunnan japonica variety Xueheaizao and Sichuan indica variety Yizila.The possible uses of Tad-M-1 in rice breeding was also discussed.
