Description
In Peru communities located above 4,000 meters, live mainly from husbandry and use the land exclusively for this purpose and those located at lower altitudes combine farming with livestock. Barley has been adapted to the highland and grow well above 3000m, and has been cultivated since XVI century in the adverse conditions of the highlands. In the highland region, 70% of barley grain production is used for human consumption directly as pearled grains, flakes and flour. Also, barley straw is used as main feed for farm animals. Prolonged droughts in the highlands have driven incentives to look for crops able to produce high quality food and forage with less water. There is evidence of improved grain yield, biomass production and nutritive quality for barley by mutation induction. 264 barley mutant lines derived of the cultivar UNALM 96 using gamma ray and commercial cultivars were evaluated for food and feed production at highland locations. Parameters such as grain yield, flowering and maturity days, total biomass yield, harvest index, were evaluated to define the agronomic performance. Protein content in grain, test weight and 1000-grain weight were measured to determine food value. Straw protein, ash content, Neutral detergent fiber (NDF), NDF digestibility (NDFD), crude protein (CP) were used to determine feed value. 24 mutant lines were selected for agronomic performance and quality traits for food and feed uses in different experiments, among them UNALM 96 M6h-602 were selected for good agronomic performance and food quality traits. For feed quality UNALM 96 M6h-1 and UNALM 96 M6h-665 because its highest value of relative forage quality (RFQ). The mutant lines selected had better values than the original cultivar UNALM96.
