在不同年份、不同父母本行比条件下研究了杂种小麦双亲花期高差对母本结实率的影响。结果表明 ,随着双亲花期高差的增大 ,母本结实率显著增加 ,结实率行间变异幅度显著降低 ;在双亲高差较小时 ,父母本行比、花期贯风对母本结实率有较大影响。讨论了适宜大田制种要求的父母本高差、行比及相应栽培技术。
In different years, parents of different parents than under the conditions of hybrid wheat parental height difference on the impact of female seed set rate. The results showed that with the increase of parents ’flowering height, the seed setting rate of maternal parent was significantly increased while the rate of variation of seed setting rate was significantly decreased. When the parents’ height difference was small, Great impact. This paper discussed the parents’ height difference, row ratio and corresponding cultivation techniques suitable for field seed production.
