| 中文摘要: |
| 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10000亩，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，单果重230～250克。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，该品种果实硬度好，耐贮运。且其具有抗番茄黄化曲叶病毒病Ty1和Ty3基因位点、抗番茄花叶病毒病Tm2a基因位点、抗根结线虫病Mi-1基因位点、抗叶霉病Cf9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。 |
| 英文摘要: |
| ‘JingFan 401’ is a new multi-resistant and high-quality tomato F1 hybrid developed by crossing inbred line ‘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 up to nearly 10000 acres, and this variety has become one of the main cultivated varieties in the Miyi area of Sichuan province. The plants of ‘JingFan 401’ are strong. And they are of mid-early maturity and of indeterminate type of growth. The fruits are of medium to large size, globe shape, smooth surface and dark-pink in color with average fruit weight 230~250g. They are high-quality and uniform, which contribute to a high commodity rate and stable high yield. The regional trial results showed this variety increased yield by more than 5%, had 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’ have good fruit hardness and are resistant to storage and transportation. This variaty is of multi-resistance, containing tomato yellow leaf curl virus resistance gene loci Ty1 and Ty3, tomato mosaic virus resistance gene Tm2a gene locus, root-knot nematode resistance gene locus Mi-1, gray leaf spot resistance gene locus Sm as well as leaf mold resistance gene locus Cf9. ‘JingFan 401’ is suitable for summer-autumn，autumn-extension cultivation in protected land and summer cultivation in open field, and is a breakthrough tomato variety of storage resistant, multi resistant and high-quality, with high market promotion prospects. |
