| Description: |
Low-input cropping systems are characterised by the reduction of pesticides and chemical fertilizers and, often, by the use of old cultivars to realize sustainable crop production which can easily integrate in the European Union agricultural subsidies. Market prices and environmental concerns favour low-input wheat production systems, nevertheless protein standards become particularly difficult to achieve in these conditions due to a minimal nitrogen supply. This study assesses the efficiency of a specific breeding program dedicated to improve yield and quality in emmer and spelt wheat in low-input environments. Ten tetraploid (emmer and durum wheat) and four hexaploid (spelt and bread wheat) wheat genotypes (including parent cultivars and offspring breeding lines selected for adaptation to low-input conditions) were investigated for 1 yr (2003-2004) in Italy in three locations in conventional and low-input cropping systems. The main agro-morphological and qualitative traits were recorded (HD, PH, GY, PC GPY, TKW, TW, GC). The results of this study show encouraging agronomic performances of new emmer and spelt genotypes under conventional and low-input cropping systems. The new genotypes are characterized by a yield potential similar to that of the modern wheat cultivar as well as by a protein content higher than old emmer and spelt accessions. The new genetic materials were also characterized by a higher responsiveness to improved environmental conditions. The results described in this study support the suitability of modern emmer and spelt genotypes, improved by introgressing wheat yield and quality traits, for organic farming in Mediterranean environments. |
