This paper deals with the initial plus trees selected in the excellent plantations, and 60 excellent phenotypes were gained. With correlation analysis, path analysis, regression analysis and clustering analysis, the results of studying the effect of 13 factors on unit yield show that the height, crown area and branching ability are highly signiflcant correlated with the unityield. Crown area, soil fertility, anthracnose infection rate, proportion of nutrient andfruited branches and meanfruit weight have...
