Abstract: This paper carries on analyse of heredity parameter for four fruit characters of green pepper. single fruit weight, length, width and thickness of fruit flesh. The result showes. 1. The Vg/Vs ratio of four fruit characters is large. It showes that these characters are effected largely by addition effect. Generally a combination with the parent which has higher cooperated ability, the reality measure value of this character of it's F1 is high too. The total effect value of every character's cooperated ability showes extreme remarkable positive correlation with reality measure value. 2. The narrow hereditary capacity of these four fruit characters is higher, so most of the variation of these four characters can be heritable to proginy stably. From the expression of the F1, the trend of F2' expression can be forecasted. 3. The own generation of the four fruit characters showes remarkable positive correlation, we can infer relavant expression of F1 by its parent's average value (MP).
