Abstract:
Six kernel-using apricot superior strains of distant hybridization were used as materials,11 appearance quality traits of stone and kernel of them were analyzed and evaluated,in order to provide reference for breeding new varieties.The results showed that the variation coefficient of 11 traits between 8.61%-35.96%,kernel shape index and single kernel weight was the minimum and maximum respectively.There were close correlation among 11 traits,the largest correlation coefficient with the single stone weight was the stone transverse diameter and the largest correlation coefficient with the single kernel weight was the single stone weight.The kernel percent were significantly correlated with the kernel lateral diameter,single kernel weight,stone shape index and kernel shape index,meanwhile negatively correlated with the stone vertical diameter,stone transverse diameter,single stone weight and kernel vertical diameter.By principal component analysis,11 appearance quality traits were transformed into 3 comprehensive indicators to represent the size,shape and yield of stone and kernel respectively.The cumulative contribution rate of 3 principal components was 85.66%.Then,according to the results of principal component analysis,11 appearance quality traits of stone and kernel of 6 superior stains were scored comprehensively,the rank was YX1>YX6>YX2>YX4>YX5>YX3.
