抗精品番茄大粉果品种‘京番401’的选育

    Breeding of A New Multi-Resistant and High-Quality Tomato F1 Hybrid - 'JingFan 401'

    • 摘要: ‘京番401’是以‘TB0824’为母本、‘TB0994’为父本杂交育成的多抗精品粉果番茄一代杂种。该品种于2020年6月获得农业农村部非主要农作物品种登记,在广州蔬菜新品种展示推广会、中国种子(南繁硅谷)大会等多次被评为专家推荐品种。近两年来该品种年均推广面积近660 hm2,目前已成为四川米易地区的主栽品种之一。该品种无限生长型,生长势强,中早熟;其果实圆形,果面光滑,果色深粉,单果质量230~250 g;果实一致性好,精品果率高,稳产高产。区域试验结果显示,该品种相比同类型标杆品种‘瑞拉’增产5% 以上,节间更短,早熟性更好。对‘京番401’耐贮运以及抗病性进行分析发现,其果实硬度好,耐贮运,且具有抗番茄黄化曲叶病毒病Ty-1Ty-3a基因位点、抗番茄花叶病毒病Tm-2a基因位点、抗根结线虫病Mi-1基因位点、抗叶霉病Cf-9基因位点、抗灰叶斑Sm基因位点,综合抗性好。该品种适于夏秋、秋延保护地以及越夏露地种植,是耐贮多抗精品番茄粉果类型的突破性品种,具有较高的市场推广前景。

       

      Abstract: 'JingFan 401' is a new multi-resistant and high-quality tomato F1 hybrid developed by crossing inbred line with 'TB0994' as male parent and 'TB0824' as female parent. This variety was registered as a non-major crop variety by the Ministry of Agriculture and Rural Affairs in June 2020. It has been recommended by experts at many events, such as the Guangzhou Vegetable Variety Exhibition and Promotion Conference and the China Seed (Southern Breeding Silicon Valley) Conference. In the past two years, the average annual planting area of 'JingFan 401' has been promoted up to nearly 660 hm2, and it has been one of the main cultivated varieties in the Miyi area of Sichuan Province. The plants of 'JingFan 401' are strong. They are characterized by mid-early maturity and indeterminate type of growth. The fruits are of medium to large size, globe shape, smooth surface and dark-pink in color, with an average fruit weight of 230-250 g. They are high-quality and uniform, which contribute to a high commodity rate and stable high yield. The regional trial results showed this variety had a yield increase by more than 5%, shorter internodes, and better early maturity when compared with those of control variety 'Ruila'. Analysis of the storage and disease resistance revealed that, the fruits of 'JingFan 401' had good fruit hardness and they were resistant to storage and transportation. This variety had multi-resistance, containing tomato yellow leaf curl virus resistance gene loci Ty-1 and Ty-3a, tomato mosaic virus resistance gene locus Tm-2a, root-knot nematode resistance gene locus Mi-1, leaf mold resistance gene locus Cf-9 as well as gray leaf spot resistance gene locus Sm. 'JingFan 401' is suitable for summer-autumn, autumn-extension cultivation in protected land and over-summer cultivation in open field, and it is a breakthrough tomato variety of storage resistance, multi-resistance and high quality, with high market promotion prospects.
