| 摘 要： | 白粒小麦品种群体中存在着高抗穗发芽的材料,水层纸巾穗发芽7天的发芽率为0。穗发芽性状表现为适续性变异,在品种群体和杂种群体都有较大的遗传变异度,GCV(％)=26.9～54.4。且具有母性遗传的特点,广义遗传力较高,h_B~2(％)=80.8～86.9。

| Abstract: | There were some varieties with high sprouting resistance in white wheat. Through germination test by using intact spikes rolled in paper towels in water, their sprouting percentage of 7 days was 0. The experimental results showed that the head sprouting character (HSC) was continuously variable. There was a wider genetic variarce of HSC in varietal and hybrid population. Maternal inheritance was showed in F1 to HSC. The broad heritabthty of HSC was higher, hB2= 80. 8% -86. 9%. |
