摘　　要：选取参加国家苦荞品种区域试验的9个苦荞品种(品系)在19个试验环境点的数据资料,使用非参数统计方法-秩次分析法对参试品种的产量进行综合分析与评价。结果表明,九江苦荞属于较高产、稳定型品种;云荞2号属较高产、稳定型品种;WK-189属于高产、平均稳定型品种;西荞3号属于较高产、平均稳定型品种;凤苦2号和凤苦3号属于较高产、低稳定型品种。In this research, data of 9 tartary buckwheat varieties which have participated in national regional trials in the 19 test environments were selected, using non-parametric statistical methods-rank analysis to analyze and evaluate the yield of the tested varieties comprehensively. The results show that Jiujiang tartary buckwheat has a comparatively high and stable yield; Yunqiao 2 has a high and stable yield; WK- 189 has a high and generally stable yield; Xiqiao 3 has a comparatively high and generally stable yield; FengKu 2 and Fengku 3 both have comparatively high but low stable yield.
