Genetic diversity analysis of melon fruit characters of 130 oriental melon germplasm materials
In order to study the genetic diversity of fruit traits of orientalmelon germplasm materials,the variation analysis,correlation analysis,principal component analysis and clustering analysis of 17 fruit related traits were investigated for 130 orientalmelon germplasm materials.The results of variance analysis showed that the diversity index of fruit related 11 qualitative and 6 quantitative traits ranged from 0.14 to 2.03,1.55 to 2.03,respectively.The average genetic diversity index of 17 fruit related traits was 1.25.The results of correlation analysis showed that there were significant correlations among several fruit related quantitative traits.Principal component analysis suggested that 17 fruit related traits were summarized into seven principal components,and the cumulative contribution rate was 80.21％.In addition,the 130 germplasm materi-als were divided into two groups in Euclidean distance 51.34.In conclusion,the fruit related traits in 130 germplasm mate-rials have rich diversity,which will lay a basis for oriental melon new variety breeding and genetic improvement.
