Comparative tests on the early yield, blossoming and fruit bearing habits and characteristics, commodity character of fruit among 6 cultivars of summer squash(Cucurbita pepo L) were conducted.

Base on the known synthetic evaluation system applied to evaluate the trade traits of primary products,the artificial neural networks(ANN) model for the trade traits of primary products was proposed,applied to evaluating of the processing characteristics in the trade traits of the fruits of tomato,and compared with the evaluation by the known evaluation results.

The entropy-weighted method was applied to synthetically evaluate the trade traits of the tomato lines fruits.
