Heterosis Analysis on Main Agricultural Characters of Pepper F_1 Hybrids

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.
