Character Variation and Principal Component Analysis of Ginkgo Cultivar Seeds

MO Zhao-zhan et al (Yulin Normal College,Yulin,Guangxi 537000)  
[Objective] The study aimed to overall and accurately reflect the classification characteristics of ginkgo cultivars.[Method] The principal component number was ascertained and the principal component equation was established through investigating 11 indices reflecting ginkgo seed characters by principal component analysis method,on which the important character indices of ginkgo cultivars were confirmed.[Result] The ginkgo seed characters were transformed into 3 independent indices by applying principal component analysis method to lower the difficulty of character analysis of ginkgo cultivars and increase reliability and stability of the analysis due to a lot of synthetic information.[Conclusion] The research could provide references for classification and breeding of nut-used ginkgo cultivars.
