Abstract
Conservation agriculture (CA) is a promising approach for solving problems of modern agriculture, as soil degradation and fertility and management of water resource, especially in the frame of the ongoing climate changes. In this scenario, it is important to identify specific genotypes adapted to specific CA-agronomic practice and requirements, like fast ground coverage, biomass accumulation, nutrient and water use efficiency. A large panel of durum wheat cultivars, comprising a wide and largely underutilized phenotypic diversity present in durum germplasm, has being characterised towards the identification of genotypes fitting with the modern sustainability/CA principles. Nearly 300 lines including elite, cultivars/breeding lines originated from stress-prone durum growing area were evaluated in a multi-environmental trial network across a range of Mediterranean environments (Morocco, Egypt, Turkey, Italy) for two years (augmented design field experiments). The panel is a subset of the Global Durum Panel previously established by the EWG of Wheat Initiative “Durum wheat genomics and breeding”, for which Illumina 90k SNP data are available. Traits considered for phenotyping and following genetic analyses were agronomic traits relevant for adaptation and grain yield, like plant phenology, growth habit, vegetation indexes, yield and its components, including spike fertility, grain morpho-metric features, grain weight and grain specific weight. Meteorological data and soil humidity have also been registered throughout the entire plant growth cycle.
