Abstract

[automatically translated] Among the grain legumes lentil (Lens culinaris Medik.), It occupies an important place in human nutrition, for the quantity and quality of proteins contained in the seed and for the content of carbohydrates associated with the low presence of anti-nutritional substances. The cultivation of lentil is still based, in most of the world, of local ecotypes and only in a few countries, such as Canada, using selected varieties. The culture, like many smaller pulses, is scarcely present in the Italian cropping systems and, in recent decades, the superficiecoltivata has fallen significantly due to, multiple factors, such as lack of selected germplasm and high production costs. Currently, the area down to lentil affects about one thousand hectares, located in the most disadvantaged areas of the mountain or hill where, however, the soil and climatic conditions give the crop good organoleptic and qualitative characteristics. The increased consumer attention to the origin and quality of the food product has directed research towards the assessment, characterization and exploitation of established genetic resources, mainly from ecotypes from different backgrounds. This paper reports the results obtained from an experimental test conducted on 30 accessions of different geographic origin lentil, being compared with the 5 most cultivated Sicilian ecotypes (1 Pantelleria, Pantelleria 2, LinosaV2, Villalba and Ustica), two commercial varieties Canadian (Eston and Liard) and 2 Spanish accessions (Spain1 and Spain2). The study was conducted in a Sicilian interior (Cammarata - Sparacia - 450 m above sea level) in a four-year period of experimentation. The tests provided for an experimental design in randomized blocks, in succession to durum wheat. They were made pheno-morphological and productive reliefs. The lines being tested showed an average weight of 1000 seeds (28.84 g) in line with the average for the Sicilian ecotypes used (28.46 g). Conversely, the value is significantly higher than the two Canadian varieties Eston and Liard (26.03 g), but lower than the average value of two Spanish accessions (42.88 g). In particular, the accessions Algerian 1 and 2, have distinguished significantly with medium, in some years, higher than 50,0g. The average height of the plants of the accessions in the study (43, 12 cm) and Sicilian ecotypes (43,85cm) was statistically lower than the Canadian variety (48.09 cm) and Spain (47.82 cm). The variability of 'flowering time was contained in the whole Sicilian material, but with an average gain of about 4-5 days compared to the Spanish accessions and to Canadian commercial varieties. The analysis of the results is good prospects for crop development through the implementation of plans of genetic improvement, mainly targeted to the increase production and improvement of the traits pheno-morphological, with the aim, among other things, facilitate the mechanization of farming operations.
