| 摘 要： | 本试验在单粒测定直链淀粉含量的条件下,对水稻杂种F_1,F_2、F_3种子进行直链淀粉含量遗传模式的探讨。结果表明:基因剂量效应仅存在部分组合。在高、中直链淀粉含量籼稻/低直链淀粉含量籼稻正反交组合中,高、中直链淀粉含量对低直链淀粉含量表现为完全显性,F_2为3:1分离,受一对基因控制。部分超亲分离表明可能还受修饰基因的影响。

| Abstract: | Based on amylose content determination done on single grain of rice, the present experiment aimed at elucidating the mode of inheritance of amylose content of rice crosses and their reciprocal including F1, F2, F3 generations. Ths results indicated that the gene dosage effect only existed in parts of the crosses and their reciprocal, in the crosses of high/low and middie/low amylose content hsren (indica) rice variety, a single major gene in association with modifying genes governed the inheritance of amylose content, high and middle amylose content was completely dominant over low amylose. |
