Analysis and Evaluation on of Fruit Quality of Main Native Apple Varieties in Yili Valley
Eight local apple varieties mainly cultivated in Yili River Valley were selected as test materials,and the core quality indexes were selected for'reasonable-satisfaction'analysis by means of correlation,factor analysis and cluster analysis,in order to provide data support for the large-scale promotion of local varieties.The results showed that there were different variations among the quality indexes,and the coefficient of varia-tion ranged from 8.15%to 41.33%.The correlation analysis of each index showed that the correlation be-tween single fruit weight and fruit longitudinal and transverse diameter,longitudinal and transverse diameter,acidity and solid acid ratio,fruit stalk length and fruit shape index was extremely significant.Five main factors were extracted by factor analysis,and the cumulative contribution rate was 99.278%.The main factor loading values were analyzed by cluster analysis,and the simplified fruit quality evaluation indexes were single fruit weight,hardness,total acid content,soluble solids and solid-acid ratio.The simplified core quality indicators were selected to calculate the'reasonable-satisfaction'and sort them.Among them,the reasonable satisfac-tion of Aboerte,Situoluowei and Kapaketagan comprehensive was up to 0.713,0.709 and 0.62,The fruit quality of these three varieties is outstanding.It is suggested to increase the promotion in the inversion zone of the Ili River Valley to better protect the high-quality germplasm resources of local apples.
