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。
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 isonucleusalloeytoplasmic 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 （7MS 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 AFI.P. The differential fragments from the cytoplasms were isolated.
