图3 两个“双顶交”F2分离群体的主要农艺性状表现 A: 株高; B: 穗长; C: 小穗数; D: 自交结实率。Pop.1+和Pop.1-分别表示含和不含6RS/6AL易位染色体的蜀麦969/HM812-41//蜀麦830/3/WJL3931 F2亚群体; Pop.2+和Pop.2-分别表示含和不含6RS/6AL易位染色体的蜀麦969/HM812-41//WJL5606/3/蜀麦126 F2亚群体。**: 表示含(+)与不含(-)6RS/6AL易位染色体亚群体间差异极显著(两尾t-test, P < 0.01)。

Fig. 3 Performances of major traits for two DTC F2 populations A: plant height; B: spike length; C: spikelet number; D: seed set ratio. Pop.1+ and Pop.1-, represent sub-population with and without 6RS/6AL translocation from Shumai 969/HM812-41//Shumai 830/3/WJL3931 F2 population, respectively. Pop.2+ and Pop.2-, represent subpopulation with and without 6RS/6AL translocation from Shumai 969/HM812-41//WJL5606/3/Shumai 126 F2 population. **: significantly difference between sub-populations with and without 6RS/6AL translocation (two-way t-test, P < 0.01).
