CORRELATION STUDIES ON SEVERAL ECONOMICAL CHARACTERS OF ACTINIDIA CHINENSIS PLANCH
Xiong Zhi-ting (Wuhan Institute of Botany, Academia Sinica)
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.
