Turnip yellows virus (TuYV) is a damaging pathogen severely reducing yields of oilseed rape (OSR) (3rd most widely grown crop in UK). UK losses are estimated at >15%, costing £69 million/annum. It also significantly reduces the yield (up to 65%) and quality of brassica vegetables (e.g. cabbage and sprouts).In earlier BBSRC-funded research, we identified sources of natural plant resistance to TuYV that were effective against the different strains of TuYV.The aim of the proposed research is to work together with commercial plant breeders from different companies to provide plant lines with our resistances to TuYV and tools (molecular markers) needed for our commercial partners to move the resistances in to commercial OSR and vegetable brassica crop varieties.The breeding of the virus-resistant varieties will increase yields, thereby helping food security and also reduce the amounts of pesticides farmers spray on crops, in attempts to stop the greenfly vectors spreading TuYV

芜菁黄化病毒(Turnip YellowVirus，TuYV)是危害油菜产量的重要病原，严重影响油菜产量。英国的损失估计为15%，每年损失6900万GB。在BBSRC资助的早期研究中，我们确定了天然植物对TuYV的抗性来源，这些来源对不同的TuYV株系有效。拟议的研究的目的是与不同公司的商业植物育种者合作，为植物品系提供我们对TuYV的抗性，以及我们的商业合作伙伴将抗性转移到商业OSR和蔬菜油菜作物品种所需的工具(分子标记)。抗病毒品种的培育将增加产量，从而有助于粮食安全，并减少农民在作物上喷洒杀虫剂的量，在阻止绿蝇媒介传播TuYV的尝试中
