Abstract
By widey samp ling in the main distribution area of Cam ellia chekiangoleosa and studying on variation offruit shape and relevance amony characters, the following results were obtaied. There were significant differences inCam ellia chekiangoleosa fruits among and within 6 p roducing areas. The collectivity of fruit variation coefficients ofthe fruitweight, the fruit height, the fruit diameter and the fruit height/diameter were 42. 07% , 15. 79% , 14. 77%and 10. 14% within the p roducing areas respectively. Within the p roducing area, the maximal and minimal variationcoefficientswere still the fruitweight and the fruit height/diameter. Significant linear correlation was found betweenthe fruit height and diameter of Cam ellia chek iangoleosa within different p roducing areas. The fruit height, the fruitdiameter were all significantly correlated with the single fruit weight within every p roducing area. But the fruitheight/diameterwas not accordantly correlated with the single fruit weightwithin different p roducing areas.
