分析小麦T 型雄性不育系种子发芽率的影响因素结果表明,小麦灌浆中后期降水可显著增加不育系种子的霉粒率和穗发芽率,从而降低了种子发芽率;不同不育系对降水的反应差异显著,粉质不育系种子的相对皱缩度、霉粒率与穗发芽率之和均显著高于半角质和角质不育系;在灌浆中后期降水年份,蜡熟期收获不育系可显著降低种子霉粒率和穗发芽率,而不会降低产种量。
Analysis of the influencing factors on the seed germination rate of T male sterile lines in wheatThe results showed that the seed germination rate of the male sterile lines could significantly increase the seed germination rate and the germination rate of the CMS lines, The response of precipitation was significantly different. The relative degree of shrinkage, mildew rate and spike germination rate of the sterile CMS lines were significantly higher than that of the semi-cuticle and CMS lines. During the late filling stage and the wax maturity stage CMS can significantly reduce the rate of seed mycelia and sprouting, without reducing the yield.
