CHANG Jun; YANG Shui-ping; YAO Xiao-hua; WANG Kai-liang

The samp les of the pecan variety were collected from Changle Tree Farm of Zhejiang Province, and thevariation and relativity of berry were studied. The result showed that pecan had great differences among differentclones. The greatest variations among the 10 participated pecan clones was the single berry weighted at 4. 60 to46141gram (CV was 19. 75 percent) , followed by the single berry-length: 2. 49 to 7. 85 centimeter (CV was 12. 78percent) , and the diameter: 1. 50 to 3. 90 centimeter (CV was 8. 42 percent). The variation of length /diameter ratiowas 0196 to 2142 (CV was 7. 29 percent) which was the smallest of all. Great linear correlation was found betweendiameter and length of different clones, i. e. the berry diameter increased with the berry length, significant linear correlation was found between the berry length and single berry-weight, berry diameter and single berry-weight. So, theweight of single fruitwas p redictable.
