Abstract:In order to reveal the main factors affecting the flavonoids content of tartary buckwheat in seeds and select high flavonoids content lines,we determined the flavonoids content in seeds of a tartary buckwheat recombinant inbred lines(RILs)population derived from a cross of“Xiaomiqiao×Jinqiao 2”.The genetic variation of seed yield,100-seed weight,seed length to width ratio,plant height,branch number and flavonoids content in seeds were analyzed on RILs population.The relationship between flavonoids content in grains and yield traits was explored by correlation analysis.Variance analysis of flavonoids content in RILs population with different seed colors or shell types was carried out,cluster analysis for the RILs population was carried out based on the phenotypic data of investigated traits,and the excellent lines were selected by variance analysis among groups.The results were as follows:(1)The flavonoids content in seeds,100-seed weight,seed yield,and seed length to width ratio of‘Jinqiao 2’were significantly higher than those of‘Xiaomiqiao’;The flavonoids content in seeds of the RILs population ranged from 1.34%to 3.05%with the coefficient variation of 12.23%;The coefficient of variation of yield traits ranged from 9.38%to 25.17%,in which grain yield was the largest,followed by 100-seed weight,and seed length to width ratio was the smallest;The tremendous transgressive segregation for flavonoids content in seeds was observed in the population.(2)There was no significant correlation between flavonoids content in seeds and the investigated agronomic traits;Seed yield was significantly positively correlated to 100-seed weight and plant height.(3)There were no significant differences in flavonoids content among lines with different seed colors or shell types.(4)The RILs population could be divided into six groups at the euclidean distance of 17.6-20.6.Group C3 and Group C6 had the highest flavonoids content in seeds,with the average values of 2.39%and 2.35%respectively.Group C2 had fine performance in plant height,branch number,seed yield,100-seed weight,and seed length to width ratio.
