| 摘 要： | 对不同地点玉米单倍体加倍率(结实率)进行研究。结果表明,单倍体的加倍率与环境、加倍方式及不同材料关系很大,通过对海南、北京、甘肃加倍环境的比较,海南单倍体加倍率较高。NH101在海南和北京两地化学加倍率均高于其自然加倍率,海南化学加倍率和自然加倍率分别为10.64%和2.93%;北京分别为7.27%和2.95%。同一环境、同样处理方式,不同类型的材料加倍率差异很大。

| Abstract: | The doubling rate of maize haploid in different planting places was analyzed. The results indicated that the doubling rate of maize haploid was affected by the environmental conditions, doubling methods and maize genotypes. The doubling rate in Hainan province was higher than in Beijing. Chemical doubling rates of NH101 were both higher than natural doubling rates, they were 10.64% and 2.93% in Hainan province, 7.27% and 2.95% in Beijing. The doubling rates of different maize genotypes were significant differences in the same environmental condition and by the same doubling method. |
