Abstract：In order to offer technical references for safflower breeding,the genetic diversity and comprehensive evaluation for 12 phenotypic traits in 150 Henan safflowers were analyzed by using principal component analysis and cluster analysis.The main results showed Henan safflowers had accordingly greater genetic diversities.The diversity index of seed number of top fruit was the highest,then diameter of top fruit,the thousand seed weight,the internode length.The variation coefficient of the total fruit number per plant was the largest,then the branch number,the seed number of top fruit,internode length,but variation coefficients of seed length and seed width are smallest.Based on genetic differences of 12 phenotypic traits,cluster analysis of 150 Henan safflowers was classified as 6 groups by genetic distance of 10.15.diameter and the seed number of top fruit were largest in the first group;the second group contained the longest seed length,widest stem width,shortest internode length;the forth group included highest thousand seed weight and widest seed width;the fifth group had good traits of highest plant height,largest node number,largest branch number,largest total fruits number per plant;but the third and sixth group had not significant benefit traits.The principal component analysis of 12 phenotypic traits showed that the top four traits principal components accounted for 70.08％ of all principal components,the first principal component was branch number and total fruits per plant and accounted for 26.07％,the second principal component was seed number and diameter of top fruit and accounted for 17.58％,the third principal component was seed weight,seed length and seed width and accounted for 14.23％,the forth principal component was height plant,height of first lateral branch and node numbers and accounted for 12.20％.The comprehensive value (F value) of phenotypic traits of safflower collections averaged 0.36.The highest F value of 0.89 was from HH085.
