| 摘 要： | 花粉植株中,一般比较健壮的植株染色体较易自然加倍,而比较细弱的植株自然加倍率则较低.据此,在分蘖期根据花粉植株的生长发育状况,把健壮的、茎粗和叶宽与种子植株相近或接近的材料选出来使其自然加倍,对较弱的植株进行药物处理染色体加倍,自然加倍与药物处理加倍技术相结合,不仅节省了人力物力,还大幅度提高了花培后代的加倍率和结实率.

| Abstract: | In the pollen plant,it is easy to double chromosome of strong seedling,but it is difficult to double chromosome of weak seedling.Accordingly,we used medical methods or natural methods to double chromosome of different seedling at tillering stage.Not only could we economize manpower and material resources,but also increase doubling chromosome and seed rate of pollen plant. |

| Keywords: | spring wheat pollen plant chromosome double double rate |
