| 摘 要： | 本文从观察玉米当代花粉植株综合授粉产生的H_2杂合体的减数分裂行为,得知H_2杂合体染色体变异频率高,后代H_3植株变异大,并通过对H_2杂合体后代的选择育种,获得优良纯系的实践,探讨H_2杂合体在玉米育种上的意义。

| Abstract: | This paper reports the study on Plantlets from cultured ma—ize cmther, H_1 by cross-pollination. The observation of H_2 miosis shows that variant of chromo—son has a high frequncy. Progeny of H_2 comprises different pl—ant types, Having selected the maize inbreed line in H_3, H_4……, a fine maize inbreed line is obtained, Through this experiment a survey has been made on the value of H_1 cross-pollination in plant breeding. |
