摘要: 以旱稻非糯性基因型远FH2-1(旱稻65×;长芒稗)为母本,高粱非糯性基因型沈农133为父本进行属间杂交,F2分离出糯性胚乳新性状。据群体1 712株调查,糯性植株为340株,非糯性植株为1372株。Χ2分析结果,该性状受两对显性基因互作影响,符合13:3抑制作用分离比例,不同于前人水稻糯性胚乳受一对隐性基因控制的遗传规律。

Abstract: A generic hybridization between Yuan FH 2-1,derived from upland rice(O.sativa)genotype Handao 65/Barnyard grass(E.caudata),and sorghum(S.bicolor) genotype Shennong 133,has been made in which parents all belonged to non-waxy endosperm(NWE) genotypes.A new character of waxy endosperm(WE) was appeared in its progenies of F2,340 WE and 1 372 NWE plants were recorded from a population of total 1712 ones.Inheritance pattern analysis of it indicated the trait was governed by 1 pair of dominant genes inhibiting effect,which was in full accordance with the segregated ratio of 13:3 by ways of χ2 tests.This was obviously different with previous reports WE were governed by 1 pair of recessive genes.

Key words: Upland rice, Barnyard grass, Sorghum, Generic hybridization, Waxy gene
