| Abstract: |
| The data of six common buckwheat varieties（lines） obtained at 37 test locations of the Regional Common Buckwheat Varieties Test of China were employed to evaluate comprehensively the yields of these varieties by combined nonparametric method and rank analysis. The results show that the tested varieties differ in yield capability and stability. Of the varieties 8802 and Pingqiao 2 have a high and stable yield and Beizaosheng has a high but unstable yield; Yuqiao 4has a middle and generally stable yield and Guyin 1has a middle-level and unstable yield while Liuqiao 1has a low but stable yield. |
