“…Essa característica atende as exigências do consumidor final, pois essa cultivar apresenta grãos maiores quando comparados às demais cultivares disponíveis no mercado consumidor (CARBONELL et al, 2008). Nesses ambientes, a cultivar 'IAC-Alvorada' obteve maior porcentagem de grãos em peneiras de número 13 e 14, estabelecida no presente trabalho como um parâmetro referente a uma aceitação de 100% pelo consumidor, justificando, dessa forma, a atribuição dos pesos/notas iguais a 10 para essas peneiras.…”

Os objetivos do trabalho foram avaliar e indicar parâmetros de seleção para classificação de grãos de feijão que atendam as exigências do mercado consumidor. Foram instalados experimentos contendo 19 genótipos de feijoeiro em nove ambientes, no Estado de São Paulo. A produção de grãos foi estratificada em peneiras de classificação 10 (10/64" pol.) a 15 (15/64" pol.) e avaliada a produção relativa de grãos em peneiras 13 e 14, rendimento de peneira, massa de 1.000 grãos, tamanho de grãos e para os índices J=perfil e H=forma do grão. A produção relativa de grãos, rendimento de peneira, forma e perfil foram as características que apresentaram diferenças estatísticas significativas, indicando presença de variabilidade genética. Por meio da comparação dos resultados com testemunhas de feijoeiro já recomendadas para o setor produtivo, conclui-se que uma cultivar de feijoeiro deve apresentar alta massa de 1.000 grãos (251 a 300g), produção relativa de grãos em peneiras 13 e 14 com valores acima de sete, rendimento de peneira acima de 70,0% e também sementes elípticas e perfil semiachatado.

“…In addition to its importance in the Brazilian diet, it is one of the agricultural products of greatest economic and social importance since it is grown on extensive areas and because of the labor it employs during the crop cycle. Considering these aspects, the common bean genetic breeding program of the IAC, undertaken in the Grain and Fiber Agribusiness Technological Research and Analysis Center of the Agronomic Institute, has made carioca common bean cultivars available with high yield capacity, resistance to the anthracnose pathogen (Colletotrichum lindemuthianum) and excellent cooking qualities (Carbonell et al 2008. Another important characteristic is the early maturity of carioca common bean cultivars for composing new production systems with seed quality and disease resistance, currently not available on the market.…”

“…The resistance observed in the cultivars IAC Alvorada and IAC Diplomata was probably inherited from IAC Carioca Pyatã, which is one of their parents (Carbonell et al 2008), known for its good levels of Cff-resistance (Maringoni 2002, Camara et al 2009, Valentini et al 2011b). The cul- tivars IPR Corujinha, IPR Tangará, and IAPAR Siriri were described as moderately Cff-resistant (Comissão 2012), in partial agreement with our results, since the cultivars IPR Corujinha and IPR Tangará were considered resistant in this study, while IAPAR Siriri was considered moderately resistant ( Table 2).…”

Reaction and colonization of common bean genotypes by INTRODUCTIONBrazil is one of the world's leading common bean producers and consumers, with a harvest of almost three million tons in 2012, in the main producing states of Paraná, Minas Gerais, São Paulo and Goiás (Agrianual 2013). Bacterial diseases are among the yield-limiting factors of the crop in the country, particularly bacterial wilt. This disease is caused by Curtobacterium flaccumfaciens pv. flaccumfaciens (Cff), and was first described by Hedges (1922) in the USA. Currently, the disease has already been detected in several countries (EPPO 2011) and Brazilian states (Valentini et al. 2010). Bacterial wilt colonizes the xylem vessels of the affected plants, leading to disruption and degradation of the primary xylem. Infected plants show symptoms of wilting leaves, which later evolve to withering and death (Dinesen 1978). Yield losses in susceptible cultivars can be close to 50% (Miranda Filho 2006). Bacterial wilt is controlled by preventive measures, e.g., by using healthy seeds, incorporation of crop bean residues into the soil, crop rotation with non-host species, and by using cultivars with some level of resistance (Huang et al. 2009, Valentini et al. 2010.A number of studies identified Cff-resistant common bean genotypes in Brazil. According to Maringoni (2002), high resistance levels were observed in the cultivars IAC Carioca Akytã, IAC Carioca Aruã, and IAC Carioca Pyatã. Souza et al. (2006) Carioca Aruã, IAC Carioca Pyatã, and IAC Carioca Tybatã, whose resistance reactions were found to be as described by Maringoni (2002) and Souza et al. (2006).
