Abstract:To reveal grain related traits affecting protein components and select excellent lines of tartary buckwheat, we analyzed the genetic variation and correlation of grain weight, grain shape and protein components using a recombinant inbred lines (XJ-RILs) population derived from a cross of Xiaomiqiao × Jinqiaomai 2. It was found that the 1 000-grain weight, grain length, grain width, length to width ratio, albumin, globulin, gluten and total protein content of Jinqiaomai 2 were significantly (P<0.05) higher than those of Xiaomiqiao, but there was no significant difference in the content of gliadin between the two parents. Among the XJ-RILs population, coefficient variation of grain weight and grain shape ranged from 5.79% to 29.97%. Tremendous transgressive segregation for all traits was observed in the XJ-RILs population. Thousand-grain weight was significantly (P<0.01) positively correlated to grain length, grain width, globulin, gluten, and total protein content. Grain length was significantly (P<0.01) positively correlated to gluten content. Grain width was significantly (P<0.01) positively correlated to globulin and total protein content. Cluster analysis based on the tested traits found that the XJ-RILs population could be divided into twelve groups at the Euclidean distance of 12.10-13.50. The mean value of grain length, length to width ratio, albumin and gluten content of group C9 were high. The mean value of 1 000-grain weight, globulin gluten and total protein content of group C10 were high. The mean value of 1 000-grain weight, grain length, length to width ratio, globulin and gliadin content of group C11 were high. The results could provide important experimental materials for further study on the genotypic differences of protein components content in grains. The excellent lines with protein components would be recommended as basic materials for processing different foods and health products.
