摘要
本文对ＩＲ＿（５４）及其辐射早熟突变系５４６０的抽穗期进行了遗传分析。结果表明：５４６０的早熟性是ＩＲ＿（５４）的一对显性基因发生单位点突变的结果，而这一对发生突变的显性基因和ＩＲ＿（５４）的另一对显性基因一起可与Ｖ＿（２０）Ａ的抽穗期基因互作，从而导致植株强感光迟抽穗。
Abstract V20A, IR54 and its early mutant line 5460 wre used as parents in three crosses. The head-ing time of 5460 was 35(1986)～40(1989)days earlier than that of IR54,and the F1 plants of5460/IR54 showed a heading time close to that of their middle-parent;The segregation ratioof early-,intermediate-and late heading plants satisfactorily agree with the 1:2:1 in the F2population, GC1 (5460
