摘　　要：对8个辣椒亲本及其组配的16个不完全双列杂交组合主要农艺性状的杂种优势进行分析,结果表明,F1代中所有农艺性状超中优势平均值均为正值,以单株产量杂种优势最为明显,为39.19%;5个农艺性状超亲优势平均值均为正值,排前3位的农艺性状分别为单果重量(15.54%)、单株挂果数(11.99%)、单株产量(10.88%);5个农艺性状之间杂种优势呈显著或极显著相关。Heterosis on main agricultural characters of eight parents and 16 hybrids which was carried followed an incomplete diallel crossing were analyzed. The results showed that the average value of min-parent heterosis of all agricultural characters was positive in the F1 hybrids, the most obvious in yield per plant, whose average value was 39.19%. The average value of over-parent heterosis of five agricultural characters was all positive, and the top three agricultural characters were single fruit weight(15.54%), fruit number per plant(11.99%) and yield per plant(10.88%).There were significant or extremely significant relationships among heterosis of five agricultural characters.
