以3个籼型水稻光温敏核不育系奥龙1S、Y58S和培矮64S为母本,6个生产上广泛使用的恢复系为父本,采用NCII设计配制18个组合,对生育期、株高及产量相关性状进行了配合力分析。结果表明,奥龙1S的单株产量一般配合力介于Y58S与培矮64S之间,高于培矮64S,且其特殊配合力方差在3个不育系中最大;生育期一般配合力与培矮64S相当;株高配合力高于2个对照不育系。
The restorer lines widely used in 6 production lines were used as the male parents of three Indica rice TGMS lines, Oron 1S, Y58S and Peiai 64S, and 18 combinations were designed by NCII design. , Plant height and yield-related traits were analyzed. The results showed that the general combining ability of Oron 1S was between Y58S and Peiai64S, higher than Peiai64S, and the variance of special combining ability was the largest among the three lines. The average combining ability Peihao 64S is equivalent; the combining ability of plant height is higher than that of two control sterile lines.
