| 摘 要： | 研究揭示了“光温敏核不育系”育性“漂移”的本质:在多基因条件下,“变异压”和“自然选择压”使两系不育系育性逐代提升。纯合体没有育性“漂移”。在适度的高海拔地区建立鉴定和繁殖基地,通过诱变、连续的自交、株系选择或花粉培养,培育出育性双向彻底转换的株系——在同一季度内,在制种基地100%不育,同时在繁殖基地像常规稻一样结实。 |
| 关 键 词： | 光温敏核不育系 两系杂交稻 漂移 纯度 育性转换 海拔 |

| Abstract: | The essence of "drift" in the fertility of "Photoperiod/thermo Sensitive Genic Male Sterile Lines(P/TGMS)" was revealed in this study.Under the condition of multiple genes,the "variation pressure" and "natural selection pressure" made the fertility of P/TGMS increase generation by generation.There was no "drift" in the fertility of the homozygotes.By selecting the bases with proper altitude for screening and multiplication,and through mutation,continuous self-breeding and strain selection or through anther culture,P/TGMS lines with complete fertility transformation of dual direction were developed,which displayed 100% sterility in the seed production bases but a similar fertility to conventional rice in the multiplication bases in the same season. |
| Keywords: | Photoperiod/thermo sensitive genic male sterility(P/TGMS) Two-line hybrid rice Drift Purity Fertility transformation Altitude |
