摘要
[目的]推广和应用恢复系万恢88。[方法]用田间试验及田间观测，之后用DPS软件分析方法，对万恢88进行一般配合力（C．CA）分析；K优88参加重庆区试试验。[结果]万恢88有效穗数、穗着粒数、千粒重和小区产量的一般配合力相对效应值为正值。分别为9．40、1．25、1．57、8．63；在1998—1999年重庆区试中，K优88连续2年均比对照汕优63增产，增幅分别为4．90％、8．42％。[结论]K优88表现出具有高产、综合抗逆性好等特点。万恢88容易测配出千粒重、有效穗及小区产量均较高的组合。
[ Objective] The aim of the study was to popularize restores line Wanhui88. [ Methods ] Based on the field experiment and field observation, the general combining ability （GCA） in Wanhui88 was analyzed by the DPS software. The Kyou88 was participated in regional trial in Chongqing. [ Result] The GCA relatively effective value of effective panicle number per plant, seed number per panicle, 1000 - grain weight, and yield per plot in Wanhui88 were positive, which were 9.40, 1.25, 1.57, 8.63 respectively. In regional trial from 1998 to 1999 in Chongqing, the yield of Kyou88 was 4.90% and 8.42% respectively higher than that of Shanyou63 as control. [ Conclusion] The charac- teristics of hlgh-yield and comprehensive resistance well of Kyou88 are displayed. Wanhui88 can easily produce the eombinations which have high 1000-grain weight, effective panicle number and yield per plot in cross test.
