摘　　要：为解决玉溪烟后本地苦荞品种退化、产量低、适应性差等问题,2020年在玉溪引种9个苦荞品种进行烟后种植试验及评价,旨在筛选出适宜玉溪烟后种植的适应性强、丰产性和稳定性好的苦荞品种。结果表明,供试苦荞品种的主要农艺性状和产量构成因子与产量呈正相关,主茎节数对产量有显著影响。各性状与产量相关性由大到小排序为主茎节数、单株粒数、主茎一级分枝、单株粒重、株高、千粒重。云荞1号产量最高,达2740.14 kg/hm^(2),较对照增产16.10%,其次是云荞2号,达2720.14 kg/hm^(2),较对照增产15.25%;黔苦6号产量排第3,达2610.13 kg/hm^(2),较对照增产10.59%。丰产性和稳定性评价表明,云荞1号和黔苦6号在烟后种植的产量水平高且稳定性和适应性好,昭苦2号和格务在玉溪烟后种植具有较好适应性、丰产性和稳定性,在玉溪烟后种植推广具有较好前景。To solve the problems of low yield and poor adaptability of local tartary buckwheat varieties after Yuxi tobacco production,nine varieties of tartary buckwheats in Yuxi were used for experiment and evaluation after tobacco production,so as to screen suitable varieties of tartary buckwheat with high adaptability,good yield and stability in Yuxi after tobacco production.Results showed that main agronomic traits and yield component factors of tested tartary buckwheat varieties were positively correlated with yield,the number of main stem nodes had significant effects on yield.The correlation degrees of different characters with yield from high to low was in the order of main stem nodes,grains per plant,first-order branching of main stem,grains per plant,plant height and 1000-grain weight.Yunqiao 1 had the highest yield,which was 2740.14 kg/hm^(2),enhanced by 16.10%compared with control,followed by Yunqiao 2,which was 2720.14 kg/hm^(2),enhanced by 15.25%compared with control.Yield of Qianku 6 took the third place,which was 2610.13 kg/hm^(2) and enhanced by 10.59%compared with CK.Fertility and stability evaluation showed that Yunqiao 1 and Qianku 6 had high yield,good stability and adaptability after tobacco production;Zhaoku 2 and Gewu had good adaptability,stability and yield,which had relatively good extension prospect in Yuxi.
