[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(GCA)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 promotion and application of restoration department Wan Hui 88. [Method] Field experiment and field observation were carried out. Afterwards, GCA analysis of Wanhui 88 was conducted by DPS software analysis method. K You 88 participated in the trial of Chongqing area. [Result] The relative value of general combining ability of effective number of panicle, panicle grain, 1000-grain weight and yield of Wanhui 88 was 9.40,1.25,1.57 and 8.63, respectively. During the trial of Chongqing area from 1998 to 1999, K You 88 increased for two consecutive years than the control Shanyou 63, an increase of 4.90%, respectively, 8.42%. [Conclusion] K You 88 showed the characteristics of high yield and comprehensive resistance. Wan Hui 88 is easy to test with a 1000-grain weight, effective spike and cell yield are higher combination.
