LLACSA, J. et al. Evaluation of promising genotypes of barley (Hordeum vulgare L.) in the centralAndesofPeru. Rev. investig. vet. Perú [online]. 2020, vol.31, n.2, e17856. ISSN 1609-9117.  http://dx.doi.org/10.15381/rivep.v31i2.17856.

The study was carried out in the central Andes of Peru aiming to evaluate promising genotypes of dual-purpose barley (greater grain and straw yield), cultivated during the dry season. Twenty-five genotypes, of which 22 were barley mutants generated by induction from the commercial variety UNA La Molina 96 were tested. A completely randomized block design with 25 barley genotypes and 3 replications per genotype was used. The yield in grain (kg/ha) and straw (kg DM/ha) was evaluated, as well as the protein content, neutral detergent fibre and in vitro digestibility of organic matter for the straw. The genotypes that showed the best characteristics for a dual-purpose barley were UNALM 96 M6h-617, followed by UNA 80 line 525 and UNALM 96 M6h-326. No significant relationship was found between grain and straw production.
