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.

BRS Camboim - wheat cultivar.

Wheat cultivar BRS Camboim was developed by Embrapa (Brazilian Agricultural Research Institution). It resulted from a double cross of Embrapa 27/Klein Cartucho and PF 869114/BR 23. BRS Camboim presents short height and good performance regarding main wheat diseases.

BRS Louro: wheat cultivar

Wheat cultivar ‘BRS Louro’ was developed by Embrapa (Brazilian Agricultural Research Corporation). It was result of a cross of PF 869114 and BR 23. ‘BRS Louro’ has excellent agronomic features, medium resistance to scab and high grain productivity.

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.

Embrapa 52: nova cultivar de trigo para o Rio Grande do Sul

In order to meet the demands for higher grain yielding wheat (Triticum aestivum L.) cultivars, in addition to higher resistance levels to diseases and better breadmaking quality, the cultivar EMBRAPA 52 was released in 1996 for the State of Rio Grande do Sul, Brazil. It was developed at Embrapa-Centro Nacional de Pesquisa de Trigo, showing early cycle, mid-high stature, and resistance to aluminum soil conditions. It can show lodging problems under high soil fertility conditions and sprouting under delayed rains at harvest time. At releasing, it has shown good plant-health performance under field conditions. At seedling stage, it was susceptible to five races of leaf rust and resistant to all races of stem rust found in Brazil. It is moderately susceptible to glume blotch and susceptible to loose smut. It is resistant under field conditions to mildew and soil borne mosaic virus. Over the 1993-95 period, EMBRAPA 52 performed as the highest grain yielding wheat among all cultivars and lines tested in Rio Grande do Sul, producing 13% over the checks in the average of all locations of the State. Considering alveograph and farinograph tests, it was preliminarily classified as superior in the commercial class, being indicated for breadmaking and to manufacture crackers and pastry products.
