Variation and Correlation of Some Fruit Characters of Loquat Germplasm Resources
摘要
Abstract
Distribution and correlation of 11 main fruit characters of 224 loquat accessions were studied.The results showed as following: wide distribution were among 11 characters such as fruit weight, soluble solid content, edible rate, vertical diameter, transverse diameter, lateral diameter, sepal length, sepal base width, calyx tube width and depth, and vertical /transverse size with coefficients of variation of 11.81%～48.92%; the distribution range of fruit weight was the widest, while that of vertical/transverse size was the narrowest; vertical /transverse size could not reflect fruit characters completely, fruit shape type with vertical /transverse size of 0.91～1.10 was the most comprehensive; and there were extremely significant positive correlation between fruit weight and vertical diameter, transverse diameter, lateral diameter, sepal length, sepal base width, calyx tube depth, edible rate and vertical /transverse size; extremely significant negative correlation between fruit weight and soluble solid content; extremely significant positive correlation between edible rate and fruit weight, vertical diameter, transverse diameter, lateral diameter, sepal length, sepal base width, calyx tube depth and vertical /transverse size; significant negative correlation between edible rate and soluble solid content; extremely significant positive correlation between vertical /transverse size and vertical diameter, fruit weight, calyx tube depth and edible rate, extremely significant negative correlation between vertical /transverse size and soluble solid content.关键词
