BRS 180: cevada cervejeira para cultivo irrigado no Cerrado

Culturas alternativas de inverno com viabilidade tecnica e economica para integrar os sistemas de producao irrigados constituem-se na principal demanda dos agricultores da regiao do Cerrado. A cultivar de cevada BRS 180 obtida pela Embrapa-Centro Nacional de Pesquisa de Trigo e Embrapa-Centro de Pesquisa Agropecuaria dos Cerrados, lancada para o cultivo irrigado em 1999, representa a primeira cultivar adaptada para a regiao, potencializando essa cultura como uma nova opcao para o produtor. BRS 180 apresenta elevados indices de produtividade, resistencia ao acamamento e baixos teores de proteinas, o que vem atender as demandas agronomicas dos agricultores e aos padroes de qualidade da industria de malte cervejeiro. Em parcelas experimentais, BRS 180 apresentou rendimentos de graos de ate 8.920 kg/ha, atingindo ate 6.000 kg/ha em lavouras comerciais.

Cevada BR 2: cultivar de cevada cervejeira resistente à mancha-reticular causada por Pyrenophora teres

Barley cultivar BR 2 developed by the Embrapa-Centro Nacional de Pesquisa de Trigo (CNPT) was released in 1989. BR 2 traces back to seven plants selected in the F3 from the cross FM 424/TR 206 made in Passo Fundo, RS, in 1979. BR 2 is a two row spring barley with wide adaptation, earliness and short straw. It is the first Brazilian cultivar resistant to Pyrenophora teres, causal agent of net blotch, a major barley disease in Brazil. In eight years of yield testing in the National Barley Trial in twelve locations of Southern Brazil, BR 2 yielded between 1,621and 4,014 kg/ha of plump kernels, with 3%, 13% and 6% yield increase over the check cultivar Antarctica 05 in the States of Rio Grande do Sul and Santa Catarina, Parana and in the mean of 96 trials, respectively. On the farm fields, BR 2 has yielded over 5,000 kg/ha. Since its approval as a malting barley in 1992, it has been widely used, taking up 30% in 1993 and 90% in 1997 of the area sown. Barley BR 2 represents a cornerstone in the history of barley breeding in Brazil and is making a significant contribution to the competitiveness of the domestic barley production.

Barley cultivar BRS 224.

1 ABSTRACT - BRS 224 barley, bred by Embrapa Trigo, is a two-rowed spring barley released in 2002 for cultivation in Southern Brazil. BRS 224 is an early maturing, medium tall and high yielding cultivar, resistant to diseases (net blotch, powdery mildew, leaf rust), lodging-resistant, and broadly adapted to the crop production regions of Southern Brazil.
