    Abstract:

    A new tomato cultivar vs Zhefen 702 with high resistance to yellow curl virus disease was bred by integrating conventional breeding and molecular marker assistance breeding, using T7969F2-19-1-1-3 and T4078F2-3-3-3 as female and male parents. The female parent was derived from progenies by crossing of‘NEMO-TAMMI’(F1)and‘T9179’. The male parent was derived from progenies by crossing of‘qirouya’(F1)and‘T9178’. ‘NEMO-TAMMI’ is the hybrid that derived from Israel with long shelf life. The variety had been approved by non-main crop committee in Zhejiang province in 2011. Through identifying multiple horticulture characters, we found that Zhefen 702 is an excellent hybrid F1 with excellent quality, early-maturing, high yield, and with diseases resistance to TYLCV, leaf mold, fusarium wilt, and tomato mosaic virus (ToMV). Its average yield could reach 73.83 t. hm-2. The variety was suitable for multiple areas in our country, peoples of which like eating pink tomato fruits.
