1. Silverleaf whitefly-resistant common beans: an investigation of antibiosis and/or antixenosis
ABSTRACT The silverleaf whitefly Bemisia tabaci biotype B is one of the most important sucking pests of common bean, which causes severe damages and requires frequently synthetic insecticides spraying to protect crop productivity. The use of common bean cultivars resistant to whitefly attack is an important strategy within an integrated pest management (IPM)

2. Carioca bean genotypes for tolerance to grain darkening by natural and accelerated methods
RESUMO O escurecimento lento de grãos é almejado por melhoristas de feijoeiro porque o consumidor considera que grãos mais escuros apresentarão maior tempo para cocção. A análise empregada atualmente leva ao redor de 90 dias para diferenciação da cor do grão entre os genótipos. Objetivou-se avaliar a cor em função do valor de L* (luminosidade) d

5. Mapping QTLs for drought tolerance in a SEA 5 x AND 277 common bean cross with SSRs and SNP markers
Abstract The common bean is characterized by high sensitivity to drought and low productivity. Breeding for drought resistance in this species involves genes of different genetic groups. In this work, we used a SEA 5 x AND 277 cross to map quantitative trait loci associated with drought tolerance in order to assess the factors that determine the magnitude of

6. New strategy for evaluating grain cooking quality of progenies in dry bean breeding programs
Abstract The methodology available for evaluating the cooking quality of dry beans is impractical for assessing a large number of progenies. The aims of this study were to propose a new strategy for evaluating cooking quality of grains and to estimate genetic and phenotypic parameters using a selection index. A total of 256 progenies of the 13thcycle of a re

7. Caracterização agronômica e seleção de linhagens de soja destinadas ao consumo humano
Soybean is the most important crop to man, because it contains in the grain, about 20% of oil and 40% of protein of low cost of production. Brazil is the second largest world producer of soybeans; however the most of the production is destined for industries of vegetable oil and the exportation in the form of grain. Even reducing the risk of chronic diseases

8. Resistance of advanced common bean lines to Fusarium root rot
Fusarium root rot (FRR) is a distributed disease of common beans in Brazil. Our main aim was to verify if there are genotypes, mainly advanced lines from the common bean breeding program with levels of resistance to FRR similar to those of the line A-300. We also compared three developmental stages for FRR assessment. Genotypes of six classes were evaluated

11. Cooking time of black beans genotypes evaluated in different environments.
Lines developed by breeding programs are expected to have improved agronomical characteristics, good culinary quality such as environment affected cooking time. Since the final quality tests of black bean lines from the Rice and Beans Research Center breeding program are carried out in a great number of environments. it is possible to determine the cooking t

12. Genetic parameters in yield recurrent selection familes in carioca type beans.
The objectives of this work were: to estimate genetic parameters; to evaluate families from recurrent selection breeding programs, comprising carioca type beans from Embrapa Rice and Beans Research Center, and to select superior families for the obtainment of lines to intercross to form new selecting populations.
