Abstract
In order to provide a theory basis and a practice guidance for resource appraise and new cultivars selection of wild apricot,correlation of fruit variation degree,variation type,fruit characters of fine individuals in Inner Mongolia with yield and kernel rate. The results show that variation of single fruit mass is the biggest in the quantitative characters indexes of single fruit mass,length,width,ratio of length to width,pulp thickness and diameter,so selection potential of the index also is the biggest. Based on variation degree of single fruit mass,fruits can be divided into six groups,i.e. small fruit,smaller fruit,middle fruit,bigger fruit,big fruit,maximum fruit. Based on variation of fruit length,fruits can be divided into seven groups,i.e. minimal short fruit,short fruit,shorter fruit,middle fruit,longer fruit,long fruit,maximum long fruit. Based on variation degree of fruit width,fruits can be divided into seven groups,i.e. extremely narrow fruit,narrow fruit,narrower fruit,middle fruit,wider fruit,wide fruit,extremely wide fruit. Based on variation degree of ratio of length to width,fruits can be divided into six groups,i.e. wide round fruit,wider round fruit,middle fruit,longer round fruit,long round fruit,extremely long round fruit. Based on variation degree of pulp thickness,fruits can be divided into seven groups,i.e. extremely thin pulp,thin pulp,thinner pulp,middle pulp,thicker pulp,thick pulp,extremely thick pulp.Based on variation degree of fruit diameter,fruits can be divided into four groups,i.e. short fruit diameter,shorter fruit diameter,middle fruit diameter,longer fruit diameter. The results of correlation analysis show that fruit characters have no significant correlation with yield,but single fruit mass,fruit length,fruit width and fruit diameter have significant correlation with kernel rate. The results of principal component analysis show that cumulative contribution rate of three principal components reaches 81.145%,the main indexes of the first principal component are single fruit mass,fruit length,fruit width,pulp thickness and fruit diameter and so on,the main index of the second principal component are ratio of fruit length to width,and the main indexes of the third principal component are yield and kernel rate.
