BRS 7762 Supremo - A black common bean cultivar with erect plant type

Abstract

BRS 7762 Supremo -A black common bean cultivar with erect plant type INTRODUCTIONDuring the 2003/2004 crop season, about 2.7 million tons of common bean were produced in Brazil on an area of 2.7 million hectares, i.e., a national average productivity of 1.000 kg ha -1 . Although the average productivity has increased, the average per capita consumption has been decreasing attaining an annual consumption of only 12.7 kg inhabitant -1 . In Brazil, the national production of black beans does not meet the internal consumption demand, which is particularly true for the states in the south as well as Rio de Janeiro and Espírito Santo. An annual import of about 100 thousand tons is necessary to meet this demand. The common bean genetic improvement program of Embrapa Rice and Beans is focused on cultivars that are more productive, more disease resistant and have an erect plant type enabling mechanical harvest, offering the final consumer a better product quality and the farmers a higher revenue. ABSTRACT -The black bean cultivar BRS 7762 Supremo developed by Embrapa Rice and Beans was released for cultivation in the States Santa Catarina, Paraná, Goiás and the Federal District. This cultivar is resistant to several rust pathotypes, to bean common mosaic virus and to four pathotypes caused by the anthracnose agent.

BRS Esteio: common bean cultivar with black grain, high yield potential and moderate resistance to anthracnose

“…The common bean breeding program of Embrapa Rice and Beans is focused on the search for cultivars with high yield potential, better disease resistance and upright plant architecture, enabling direct mechanical harvesting, so farmers can sell a better quality product and increase returns from the crop. With these objectives, some new cultivars with black grain were released in recent years, e.g., BRS 7762 Supremo (Costa et al 2006) with excellent plant architecture; BRS Campeiro (Carneiro et al 2004) with a semi-early cycle; and BRS Esplendor (Costa et al 2011) with upright growth and multiple disease resistance.…”

Breeding methods and history of bean cultivars released in CBAB - Crop Breeding and Applied Biotechnology

“…In the latter case, for the early generations of the populations the bulk method was used, with Colletotrichum lindemuthianum inoculation, to eliminate susceptible plants. The remaining population was conducted by the SPD method (Costa et al 2006). The bulk method was most used for improvement by Embrapa Rice and Beans.…”

“…SO Moreira et al In terms of disease resistance, the use of resistant cultivars has been the most effective control method . Among the most important diseases of common bean are anthracnose (caused by Colletotrichum lindemuthianum) and angular leaf spot (caused by Phaeoisariopsis griseola) (Costa et al 2006).…”

Manejo da irrigação no feijoeiro cultivado em plantio direto

“…Obteve-se média de 30,15 g para 100 grãos. As médias obtidas foram superiores à média de 100 grãos da cultivar BRS Supremo o que, segundo Costa et al (2006), apresenta média de massa de 100 grãos de 25 g. Os resultados observados neste trabalho diferem dos obtidos por Pavani et al (2008) que, de forma similar, avaliaram o desempenho do tanque Classe A e da tensiometria em plantio direto e verificaram efeito dos regimes hídricos diferenciados sobre a massa de 1000 grãos do feijoeiro.…”
