摘 要 ：改良水稻雄性不育系的柱头外露率对于提高杂交水稻制种产量具有重要意义。本研究结果表明:柱头外露率属数量性状,各世代均呈连续性变异;该性状不存在细胞质遗传现象,但不育性可能对该性状有增进效应;在控制该性状的各基因效应中,以显性最为重要,其次为加性,上位性的影响较小;各组合柱头外露率的广义遗传力均较高,为0.90左右,

Abstract:The stigma extrusion is very important for increasing yield of hybridrice and seed set of conventional varieties.The results obtained in mystudy are as follows:1.Stigma extrusion was of quantitative inheritance,and variationsin stigma exsertion was continued in each generation.2.There was no occurre
