１９８８～１９９４年从开花习性好的六千辛Ｂ与配合力好的盐粳２号Ｂ杂交后代中，育出综合二者优点的六盐Ｂ，再与ＢＴ型六千辛Ａ连续回交，转育成生育期和株高不同的系列六盐不育系。６个不育系与３个恢复系双列杂交配合力测定表明，六盐１８９Ａ一般配合力最好，其次为徐稻２号Ａ、３７２６Ａ，它们与六千辛Ａ有显著差异；六盐１８６Ａ一般配合力效应与六千辛Ａ无显著差异，但始穗期早１５天，有利于Ｆ１制种。恢复系中４４８２一般配合力最好。特殊配合力好的组合有六盐１８９Ａ／４４８２、３７２６Ａ／４４８２和六盐１８６Ａ／４４８２等
From 1988 to 1994, Liuqianxin B with good flowering habits and Yanjing 2 with high combining ability were bred with six salt B to synthesize the advantages of the two, and then backcrossed continuously with BT type Liuqianxin A, Transformed into a series of six salt sterile lines of different growth stages and plant height. The determination of the combining ability of six lines with three restorer lines showed that the six-salt 189A had the best combining ability, followed by Xudao No.2 A and 3726A, which had a significant difference with Liuqianxin A; the six salt 186A The general combining ability effect and Liuqianxin A no significant difference, but early 15 days early heading, is conducive to F1 seed production. 4482 in the restore system with the best general cohesion. Special combinations with a combination of six salt 189A / 4482,3726A / 4482 and six salt 186A / 4482, etc.
