从亚洲蔬菜研究中心和美国引进材料的杂交后代中,进行株系选择,有效地将生长势强、抗病、果肉果皮厚的性状转育到稳定株系9709上,并以此作母本,与从合作903后代中分离出的大果型稳定株系9803作父本配成组合。经组合力测定,生产性试验和各地试种示范,选育出了高抗TMV、耐叶霉病、优质、大果的有限生长类型番茄一代杂种——浙杂809。 From the Asian Vegetable Research Center and the introduction of the United States to introduce cross-breeding material, the line selection, effectively growing strong, disease resistance, fruit pericarp thick trait transferred to the stable line 9709, and as a female parent, And 909 offspring from the cooperation of the large fruit-based stable strain 9803 father dubbed combination. Through the determination of combinatorial force, productive test and demonstration of breeding in different places, the tomato hybrid F1108, Zhaza 809 with limited resistance to TMV, resistance to leaf mold, high quality and large fruit, was bred.
