Abstract：Research on heredity trend of morphological characters of tomato germplasm resource,in order to understand the relationship among species.The experiment hopes to provide theoretical basis for the exploitation and utilization of tomato germplasm resources.Inheritance of some characters including stem length,foliage index,canopy were studied with 50 jianhuang,47(A-6t),93-29,A33-1,46(A-10t),93-11,A-17,49(7-1t),48(7t)and F1 progenies from 93-29×A33-1,50jianhuang×47(A-6t),46(A-10t)×93-11,50jianhuang×A-17,93-11×49(7-1t),3-11×48(7t). Through cross breeding can change the partial morphological characters of the tomato so as to improve the yield quality and resistance of the tomato.
