Genetic diversity analysis of fruit characteristics of hawthorn germplasm

K. Su, Guo, Y. S., Wang, G., Zhao, Y. H., and Dong, W. X., Genetic diversity analysis of fruit characteristics of hawthorn germplasm, vol. 14, pp. 16012-16017, 2015.

One hundred and six accessions of hawthorn intraspecific resources, from the National Germplasm Repository at Shenyang, were subjected to genetic diversity and principal component analysis based on evaluation data of 15 fruit traits. Results showed that the genetic diversity of hawthorn fruit traits varied. Among the 15 traits, the fruit shape variable coefficient had the most obvious evaluation, followed by fruit surface state, dot color, taste, weight of single fruit, sepal posture, peduncle form, and metula traits.
