Abstract: By using an intersubspecific DH population (02428/Teqing), the inheritance mode of rice apparent amylose content(AAC) together with its two components hot water insoluble amylose content (HISAC) and hot-water-soluble amylose content(HSAC) was studied. It was revealed that HISAC and HSAC were controlled by two non-allelic genes, Amyi(t) for HISAC and Amys(t) for HSAC, respectively. These two genes were highly linked, with a genetic distance of 12.9 cM. Therefore, AAC was controlled by two non allelic genes, however, it looked like a single locus because of their linkage.

摘要： 利用籼粳交(02428/特青)花培DH群体，研究了稻米表观直链淀粉含量(AAC)及其组成因子——热水不溶性直链淀粉含量(HISAC)和热水可溶性直链淀粉含量(HSAC)的遗传特性。结果表明，HSAC和HISAC都表现为一对主效基因遗传，且两者表现为连锁遗传关系。用Amy-s(t)表示控制HSAC的基因，用Amy-i(t)表示控制HISAC的基因，两基因的连锁遗传距离为12.9 cM。由于Amy-s(t) 和Amy-i(t)相互连锁，因此AAC在总体上表现为一对基因遗传。
