摘要
本研究选用 7种细胞质源不同的滇型不育系为母本 ,10个常用品种或品系为父本 ,得到 70个杂交组合。通过分析70个杂交后代的花粉可育度和自然结实率可知 ,这 7个细胞质源不同的滇型不育系之间的保持关系基本一致 ;5个滇一型恢复系对这 7个不育系的恢复能力差异较大。鉴于 7种不同细胞质源不育系的保持关系相同 ,使转育同核异质不育系成为可能 ,从而为实现滇型杂交水稻细胞质多样化提供了实验依据。
In this study 70 hybrids were obtained by cross between seven Dian type sterile lines with different cytoplasms and ten strains selected as female parents and as male parents,respectively.The pollen fertility and the seed setting percentage of these materials were also studied. The results showed that the maintenancee is mainly consistent for these 7 Dian type sterile lines.The restoring abilities to these seven Dian type sterile lines were different to a great extent. Because the relationship of maintenance is mainly consistent in seven sterile lines with different cytoplasms, it is possible to breed many sterile lines with same cytoplasm. This provided experience for cytoplasmic diversity in Dian type hybrid rice
