BRESOV deals with the urgent need to provide climate-resilient cultivars addressed to organic vegetable production systems. These new cultivars will benefit organic growers and the organic seed industry, providing much needed security both under current and future scenarios of climate change. In this project, we will exploit the genetic variation of brassica, bean and tomato for enhanced productivity, by exploiting up-to-date knowledge of genome structure and function. This work is enhanced by the active involvement of farmers, advisory services, research institutes, breeding companies and food processors from diverse geographical/climatic contexts in Europe and Non-EU countries. The selection of pre-breeding and breeding lines for the three species is undertaken in organic vegetable farming systems, utilizing an annual crop rotation scheme. New cultivars will be selected for efficiency when grown under drought, high temperature, and low nitrogen stresses, for resistance to some pests and diseases, for desirable product quality traits such as taste, visual appearance, bioactive compounds, or post-harvest performance. Crop genetic diversity is broad as we are utilizing several landraces (LRs) and crops wild relatives (CWRs) provided by partners for the pre-breeding and breeding activities. We adopt an innovative approach, where plant traits related to the roots-zone, and to root-growth, and architecture that enable a better interaction with organic soil and its microbiome, are sought to benefit the end-users. This approach will ensure that the available genetic resources and bred germplasm, combined with the best on-farm management practices will enhance resource use efficiency and productivity. The germplasm from this project will act to pump-prime the production of new seed for the organic growing sector and will also serve as a model for the enhancement of other crops.
