| 摘 要： | 四川无融合水稻(SAR-1)是1988年春在南繁育种材料中首次发现的新种质.该材料花粉高度不育,能大量单性结实.其基因不仅能世代相传,而且可通过杂交转移到其他材料上.经细胞胚胎学研究表明:SAR-1具孤雌生殖特性,还可能具有不定胚发生途径.SAR-1的极核未经受精,能自发形成胚乳.

| Abstract: | Sichuan Apomixis Rice (SAR-1) is a new gormplasm which was discovered in 1988. SAR-1 is highly male sterile, but could seed setting automatically. It was found, by embryological studies, that the polar nuclei could divide and form endosperm and the egg cell could develop mature embryo without pollination and fertilization. The genetic analysis showed that the apomictic genes could inherit from generation to generation and be tran-sfered to other rice materials by hybridization, |
