The heritability of plant height, length of flag leaves, width of flag leaves, length per spike, spikes per plant, spikelets per spike, grains per spike and biomasses per 100 grains were 93%, 78%, 18%, 81% , 38% , 64% , 29% and 74%, respectively. The least genes controlling the characteristics were 3, 4, 13, 4, 8, 5, 9 and 4, respectively. Based upon estimated coefficients of skewness (g1) and，kurtosis (g2 ) of those traits, it would be concluded that gene interaction was absent for plant height, length per spike, and grains per spike, complementary gene interaction was found between width of flag leaves and spikelets per spike. However, maybe complementary gene interaction was found among length of flag leaves, spikes per plant and biomasses per 100 grains. keywords:Wheat  Doubled haploid population  Quantitative characters  Genetic analysis 查看全文  查看/发表评论  下载PDF阅读器
