Abstract: The characteristics of a novel cytoplasmic male sterile (CMS) line derived from Oryza sativa subsp. javanica cv. Wanilava (denominated as JWtype) were analyzed. Two sets of isonucleusallocytoplasmic lines (273D, 273JW and 273B; 803WA, 803JW and 803B, respectively) were bred by advanced backcrosses using the maintainer lines (273B and 803B, respectively) as recurrent parents, each containing individual cognate nucleus with different cytoplasms. Considerable genetic diversities between CMSJW (CMS from javanica cv. Wanilava) and CMSWA (CMS of wild abortive from O. rufipogon) or CMSD (CMS from African indica cv. Dissi) were revealed by AFLP. The differential fragments from the cytoplasms were isolated.

Key words: cytoplasmic male sterility, isonucleusallocytoplasmic lines, amplified fragment length polymorphism, fingerprint, javanica rice

摘要: 初步鉴定了爪哇稻Wanilava细胞质雄性不育系的特征特性,并以2套水稻(Oryza sativa)同核异质材料273JW(爪哇型胞质不育系)、273D(D型胞质不育系)及其对应的保持系273B, 803JW(爪哇型胞质不育系)、803WA(野败型胞质不育系)及其对应的保持系803B为研究对象,利用AFLP 分子标记技术构建了JW型不育胞质的指纹图谱,分离了JW型胞质与野败型胞质及保持系的差异片段。
