自１９８７年开始，利用云南地方品种和优良的粳、籼品种，采用常规杂交、回交及连续多代自交等方法，通过异地种植鉴定选择，成功地培育出具有云南地方品种质源，具有较好农艺性状，育性转换明显而稳定的新型温敏不育系滇农Ｓ－１和滇农Ｓ－２等．研究表明，以云南地方品种为主要亲本进行常规杂交培育温敏不育系，是一条行之有效的途径．试验表明，从现有滇型水稻不育系中直接筛选温敏型不育系也是可行的 Since 1987, Yunnan local cultivars, fine japonica rice and indica cultivars have been successfully cultivated with Yunnan local cultivars by conventional methods such as crossing, backcrossing and multiple generations of selfing, The new thermo-sensitive sterile lines Diannong S-1 and Diannong S-2 with good agronomic traits and fertility transformation were obviously stable. Studies have shown that it is an effective way to cultivate thermo-sensitive genic male sterile lines by routine hybridization with Yunnan native breeds as the main parents. Experiments show that it is feasible to directly screen the thermo-sensitive genic male sterile lines from the existing Dian-type CMS lines
