Abstract： To investigate the relationships among major agronomic traits，quality traits，and yield in black wheat germplasm resources in Xinjiang， 5O black wheat germplasm accesions were analyzed. Six agronomic traits and nine quality traits were evaluated through correlation analysis，principal component analysis，and cluster analysis. The coefficient of variation（CV）ranged from 1.30% to 51.49% . Among the agronomic traits， the numberoffertilespikelets exhibited the highest CV，while among thequality traits，dough stability time showed the greatest variation. Correlation analysis revealed one trait pair with a significant correlation （ p<0.05 ）and eleven trait pairs with highly significant correlations（ p<0.01 ）. However，no significant correlations were observed betweenagronomic traits，quality traits，and yield.Principal component analysis （PCA）reduced the 15 traits into six principal components，accounting for a cumulative contribution rate of 73.76% ，thereby capturing the majority of genetic variation. Cluster analysis grouped the 5O black wheat germplasm accesions into three distinct clusters.These results provide a theoretical basis for the improvement and parental selection of black wheat germplasm resources.
