　　利用糯稻与非糯稻品种（苏香粳3号和武运粳稻7号）杂交，用单粒法测定了亲本、F1、F2、B1 F1及B2 F1的直链淀粉含量，以研究其直链淀粉含量的遗传特性，结果表明：糯稻与非糯稻亲本杂交F1直链淀粉含量多偏向于母本，存在基因剂量效应；高直链淀粉含量对糯性表现为完全显性，是由1对主效基因控制的；糯稻与低直链淀粉含量品种杂交的F2代不符合1∶3的分离比例，这说明控制低直链淀粉含量基因对糯性表现为不完全显性，与控制糯性的基因（wx）是非等位的。

The glutinous rice variety Suxiangjing No .3 and non-glutinous rice variety Wuyunjing No .7 were hybridized, the amylose contents of the parent, F1 , F2 , B1 F1 and B2 F1 were determined by using simple grain method , and the genetic characteris-tics of their amylose content were studied .The results indicated that the amylose content of F 1 hybridization between the glutinous rice and non-glutinous rice parent was more similar to that of female parent , and there was a gene dosage effect in amylose content . High amylose content was completely dominant to wx, and it was controlled by a pair of major genes .The amylose content of F 2 hy-bridization between the glutinous rice and low -amylose-content mutant rice was not compliant with the separation ratio of 3∶1, which showed the low -amylose-content gene was incompletely dominant to wx, and it was not allelic with wx gene controlling the glutinous quality.
