Abstract

Based on a specimen correlation matrix，eight major economic characteristics，including fruit shape coefficient，average nut weight，shell thickness of the nut，kernel ratio，kernel weight，kernel fat content，protein content，and fruit yield per square meter of projected tree crown area，for 12 cultivars of Carya illinoensis were determined using a principal component analysis. Results according to more than 83.99% of the cumulative variance，showed that the three principal components and their functional equations were：kernel ratio，average nut weight，kernel fat content. Key principal component values of various cultivars were：kernel ratio（43.329%）. Superior cultivars were determined as average nut weight with the results being similar to a practical phenotype. ［Ch，1 fig. 4 tab. 6 ref.］
