Breeding disease-resistant heirloom-quality tomatoes – Natural Farming Analysis Basis


Carol Deppe, Proprietor Fertile Valley Seeds

The thing of this mission is to breed disease-resistant heirloom-quality tomatoes, particularly these proof against late blight and a variety of different ailments. I’ve already crossed ten premiere heirloom tomato varieties—full-size pink, pink, black, orange, and paste varieties—to the hybrid ‘Iron Woman’, which is proof against late blight and a variety of different related ailments. And I’ve developed the second-generation (F2) populations from every of those ten crosses. This 12 months, the grant 12 months, I’ll use marker assisted choice to determine many of the illness resistance genes in every transplant earlier than transplanting them to the sphere. (This entails taking a pattern of leaf from every transplant and sending the samples to a laboratory that may determine the genes in every pattern.) This fashion I’ll have the ability to plant solely the transplants which have the fascinating illness resistance genes. I’ll consider crops within the discipline based mostly upon plant type and vigor, maturity, fruit coloration, form and taste. I’ll derive a variety of numerous seed from every cross. These numerous seed will probably be distributed far and extensive to permit natural farmers and gardeners to simply develop their very own heirloom-quality tomato varieties with resistance to trendy illness. Lots of the numerous seed will already be pure-breeding for late blight resistance, so breeders working with it is not going to want to pick for late blight resistance. (You would possibly or won’t have it in your discipline any given 12 months.)
