| 摘 要： | 通过对四川5个具有代表性恢复系所配组合即MH63系列、CDR22系列、FH838系列、MH725系列和SH527系列的分析得出,除了SH527系列品种的平均产量为8.25 t/hm2外,其余几个系列产量水平相当;在主成分分析中SH527系列品种的第一主成分因子是有效穗粒数因子,而产量构成因素三者与产量之间的直接通径系数相近,说明三者对产量的作用都相当,这说明当其穗粒数达到一定高度时,穗数因子又成为新一轮产量增长的限制因素。

| Abstract: | Through analysis of the varieties combined by major restorer lines MH63,CDR22,FH838,MH725 and SH527 of Sichuan in hybrid rice,the results indicated that the mean grain yield of 4 lines varieties are similar,except 8.25 t/hm2 of variety restorered by SH527;in principal component analysis,the first principal component of variety restorered by SH527 is effective panicle and number of filled grain per panicle and the 3 factors of yield play important role together in yield.It shows that number of panicle become... |
