中华猕猴桃若干经济性状的统计相关研究

本文运用相关系数及聚类分析方法对湖北中华猕猴桃四十二个株系或品系的十五个经济性状之间的相关性进行了统计分析。结果表明:1)果实重量和大小与果实品质无显著相关;2)果肉颜色,果实风味及可溶性固形物含量之间显著相关;3)果实形状与果实被毛状况及果顶凸起程度显著相关,而与果重和果实品质无显著相关。文中讨论了这种统计学相关性在中华猕猴桃育种中的实践意义,可为目前中华猕猴桃育种工作提供参考。

CORRELATION STUDIES ON SEVERAL ECONOMICAL CHARACTERS OF ACTINIDIA CHINENSIS PLANCH

The correlations among fifteen economical characters of 42 cultivars or Strains of Chinese gooseberry (belonging taxonomically to Actinidia chinensis var. chinensis and A. chinensis var. hispida) were analysed statistically using WPGMA. It is shown that there is significant positive correlation between fruit weight and fruit size, while the correlation between fruit weight and fruit quality is insignificant. The flavour of fruit becomes better when the flesh color turns from green through light green to yellow and light yellow. These changes are accompanied by the raising of the content of soluable solid-state substances in fruit. Long-typed fruits are often covered with thick and hard hairs. Neither fruit weight nor fruit quality is correlated to the shape of fruit. The conclusions reached here can be of some use for the breeding practice of Chinese gooseberry.
