高抗番茄黄化曲叶病毒病番茄新品种浙粉702的选育

Breeding of a New Tomato Variety Zhefen 702 with High Resistance to Tomato Yellow Leaf Curl Virus

高抗黄化曲叶病毒病番茄新品种浙粉702是以自育株系材料T7969F2-19-1-1-3为母本、T4078F2-3-3-3为父本,结合分子标记辅助技术选育的杂交一代粉红大果型番茄品种。母本T7969F2-19-1-1-3系从以色列引进的耐贮运番茄品种NEMOTAMMI(F1)与抗叶霉病粉红株系材料T9179杂交分离后代中,经连续9代单株选择而成。父本T4078F2-3-3-3系从荷兰引进的抗TYLCVD番茄品种奇诺亚(F1)与粉红株系材料T9178杂交分离后代中,经连续8代单株选择而成。该品种2011年通过浙江省非主要农作物认定委员会认定。通过对浙粉702的农艺学、产量、品质和抗病等性状鉴定,结果表明:浙粉702品质优良,早熟,丰产,高抗番茄黄化曲叶病毒病和枯萎病,抗叶霉病和番茄花叶病毒病,适合我国喜食粉果地区种植,平均产量可达73.83 t/hm2。

A new tomato cultivar 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 was 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 was an excellent hybrid F1with 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 / hm2. The variety was suitable for multiple areas in our country,where peoples liked eating pink tomato fruits.
