BRS 180: cevada cervejeira para cultivo irrigado no Cerrado

Abstract

Culturas alternativas de inverno com viabilidade técnica e econômica para integrar os sistemas de produção irrigados constituem-se na principal demanda dos agricultores da região do Cerrado. A cultivar de cevada BRS 180 obtida pela Embrapa-Centro Nacional de Pesquisa de Trigo e Embrapa-Centro de Pesquisa Agropecuária dos Cerrados, lançada para o cultivo irrigado em 1999, representa a primeira cultivar adaptada para a região, potencializando essa cultura como uma nova opção para o produtor. BRS 180 apresenta elevados índices de produtividade, resistência ao acamamento e baixos teores de proteínas, o que vem atender às demandas agronômicas dos agricultores e aos padrões de qualidade da indústria de malte cervejeiro. Em parcelas experimentais, BRS 180 apresentou rendimentos de grãos de até 8.920 kg/ha, atingindo até 6.000 kg/ha em lavouras comerciais.

Characterization and genetic variability of barley accessions (Hordeum vulgareL.) irrigated in the savannas based on malting quality traits

“…The high value for BRS Deméter is in accordance with the data observed by Amabile et al (47). The BRS 180 cultivar also showed a value of 48.2, higher than those found by Silva et al (48), which ranged according to the micromalting performed. According to Ogushi et al (51), high values might be explained by the modification stage of the malt and malting process used or might be partially elucidated by the higher level of starch degradation along with the higher thermostability of the β-amylase.…”

“…A high viscosity results in a longer beer clarification process and a difficult filtration. Following the same tendency of the extract, BRS 180 and BRS Deméter cultivars showed higher viscosity values than those verified by Silva et al (48) and Amabile et al (47). These high values might be also related to the high protein content in the grains, according to statements made by Mather et al (33).…”

“…The same yearly variation was identified by Silva et al . for BRS 180 cultivar. These results show that even genetic material already introduced as a malting barley might not maintain the index that it had when first introduced, owing to the influences of the environmental conditions .…”
