| Abstract: |
| Genetic diversity analysis, principal component and cluster analysis were performed on 180 accessions of hulled and naked Tartary buckwheat to investigate genetic diversity of agronomic traits in western Jilin. The results showed that coefficient of variation of seed weight per plant and number of seeds per plant was higher than 60%. The principal component analysis on 12 agronomic traits showed that the accumulative contribution rate of the first four principal components accounted for 82.729% of the total variation. The first principal component mainly reflected the grain shape, while the second principal component reflected the yield. The third and fourth principal components reflected the grain size and plant type, respectively. According to the genetic difference of each characteristic among varieties, 180 accessions were classified into 3 categories by cluster analysis. The first group could be used as excellent parents for breeding dwarf and special grain\|shaped varieties, the second group could be used as excellent parents for breeding high\|stalk varieties, and the third group could be used as excellent parents for breeding high\|yield and large grain varieties. Based on three aspects of dwarf, high yield, and large grain, a total of 14 excellent Tartary buckwheat germplasm resources were selected including 4 dwarf varieties of lingshikuqiao, kuqiao 60, kuqiao 62 and anzekuqiao, 6 high yield varieties of ergekuqiao, wuxiangkuqiao, kuqiao 27, laoyajukuqiao, kuqiao 34 and kuqiao 35, and 4 large grain varieties of luxikuqiao, ejiaowachi, yaoankuqiao 1 and kuqiao 61. |
