Abstract
[Objective] To study genetic model and genetic effect of main quality characters of tomato.[Method] Six parents of tomatoes were tested in the complete parallel cross design.The genetic model,gene effects of 8 quality characters were studied.[Result] Very significance was found in quality characters of parents,the selection of parents was effective.Very significance was found between characters.Among 8 characters,fruit shape index and lycopene can be explained with the additive-dominance model in reciprocal crosses.The dominant effects among(direct cross) combinations of the two characters were more important than the dominant effects of them,and the genetic effects showed active recessive effects.The broad sense hereditabilities were more than 50％,the narrow sense hereditabilities were less than 50％,it had over dominance effects.The performance of reciprocal cross was on the contrary.Other characters didn't meet additive-dominance model because of no dominance effects or epistasis effects.[Conclusion] The study provides a theoretical basis on apolegamy of tomato advantage combination.关键词
