摘要：

摘要：本文研究了不同基因型不同播期玉米单倍体的自然加倍效果。结果表明：不同基因型单倍体自然散粉率差异很大；单倍体的自然散粉率为6.56%～65.33%；夏播自然散粉率比春播高3.77%，自交结实率为6.23%～9.39%，单倍体自交结实率夏播比春播高2.37%；夏播有利于单倍体自然散粉及自交结实。

Abstract:

Abstract:The natural doubled effect of maize haploid in different sowing was studied in this research;The results showed that there was big difference with different genotype of haploid in natural pollinating rate;The average natural pollinating rate of haploid was 6.56%～65.33%;The natural pollinating rate in summer sowing was 3.77% higher than in spring sowing,self-fertility rate was 6.23%～9.39%,and the self-fertility rate of haploid in summer sowing was 2.37% higher than spring sowing;Summer sowing was better for the natural pollen dispenser and self-fertility.
