Thus, the aim of the present study was to evaluate the genetic diversity of 215 common bean accessions, which included cultivars, obsolete cultivars, improved lines, and landraces using morpho-agronomic and biochemical traits, and amplified fragment length polymorphism markers (AFLP). Genetic parameters, box plots, Pearson’s correlation analysis, and Ward’s hierarchical clustering were used to analyze the data. The Jaccard similarity coefficient and neighbour-joining clustering method were used for molecular analysis. A wide variability among the accessions was observed for morpho-agronomic and biochemical traits. Selective accuracy (Ac) and broad-sense heritability (h2) values were high to intermediate for all traits, except seed yield. Ward’s hierarchical clusteri...

Six cultivars of the “Carioca” group (“Pérola,” “IPR Siriri,” “IPR Eldorado,” “BAT 477,” “Campeão 2,” and “Aporé”) and 7 cultivars of the “Preto” group (“IPR,” “Uirapuru,” “IPR Graúna,” “IPR Tiziu,” “IPR Tuiuiú,” “FT Soberano,” “BRS Esplendor,” and “BRS Supremo”) were evaluated at 2 levels of phosphorus (6.25 and 25.02 μM L-1). The experiment was conducted in a greenhouse and arranged in a completely randomized factorial design with 6 replicates, and the dry weights of the shoots (fractioned into the dry weights of the stems, leaves, pods, and beans) and roots were evaluated at physiological maturity. Phosphorous content was determined in these vegetative structures using an atomic emission spectrophotometer, and indices of P absorption, translocation and use efficiency were then quantified. Statistically significant difere...

In this sense, this study aimed to estimate the following genetic parameters: genetic variances, heritability coefficients in narrow and broad sense and predict the selection gain for the Fe, Zn, Mg and P contents in common bean grains. The crosses were made between cultivars: FT Nobre x IPR Gralha and Diamante Negro x IPR Chopim. The genitors (P1 and P2) were crossed resulting in F1 and F2 generations and backcrosses BC1 (P1 x F1) and BC2 (P2 x RC2). The mineral contents of Fe, Zn, Mg and P in grains were measured by nitric-perchloric digestion using atomic emission spectrometry coupled with plasma (ICP-OES). The predicted gains for the first cycle of selection were positive, indicating the viability of the increaseof the minerals Fe, Zn, Mg and P levels on common bean grains using classical breeding methods. The prediction gains obtained in the first cycle of selection ...

Two independent experiments, one for each group, were set up in Londrina in the year 2000 wet season. A randomized complete block design was used with splitplots and three replications. The plots consisted of treatments with and without water stress and the splitplots of cultivars and lines. Grain yield and grain yield components were assessed. There was genetic variability among the cultivars and lines, as detected by the estimates of the genetic, environmental variation coefficients and B index. Water stress reduced grain yield by, approximately, 50%, but the IPR88 Uirapuru cultivar, from the black commercial group, and the LP 97-13 and LP 97-4 lines from the carioca commercial group stood out as drought tolerant and showed with high yield potential.

O objetivo deste trabalho foi avaliar a variabilidade genética, o efeito ambiental e a estabilidade para o teor de proteína em grãos. Na safra da seca 2006, foram conduzidos dois experimentos, um para o grupo comercial carioca e outro para o grupo preto, em três locais do Estado do Paraná. O delineamento experimental utilizado foi o de blocos casualizados com três repetições e parcelas constituídas de quatro linhas de 5 m, espaçadas 0,50 m. Na maturidade fisiológica, retiraram-se amostras de 200 g de grãos de cada parcela experimental; estas foram armazenadas em câmara fria até a realização das análises do teor de proteína. A análise de variância conjunta revelou efeito significativo do genótipo, do ambiente e da interação genótipo por ambiente. Estes resultados indicam a existência de variabilidade genética entre as cultivares e linhagens de feijão estudadas e que esses genótipos comportaram-se de maneira diferenciada nos diferentes ambientes onde foram avaliados. Os genótipos de feijão que apresentaram maiores teores médios de proteína, ampla adaptabilidade e alta estabilidade de comportamento foram: FT120, FT Soberano, Xamego e LP99-96 (grupo preto); BRS Pontal, FT Magnífico, IAC Tibatã, IAPAR 81, IPR Juriti e Pérola (grupo carioca).

O experimento foi conduzido dentro de casa de vegeta ção, no campus do Centro de Ciências Agrárias da Universidade Federal do Espírito Santo (CCAU FES), Alegre, ES. Devido ao grande número de genótipos a serem avaliados o experimento foi realizad em duas fases. O delineamento utilizado foi o inteiramente casualizado no esquema de parcela subdivididas, sendo a umidade do solo no período de estresse hídrico determinada a intervalos d dois dias, pelo método EDABO (Evaporação Direta da Água em Banho de Óleo). Em termos d produtividade, não foi possível verificar diferenças significativas entre os sistemas de cultivo sem com estresse, para os genótipos

O objetivo deste trabalho foi avaliar os efeitos da interação genótipo por ambiente na produtividade de grãos em linhagens e cultivares de feijoeiro, com a finalidade de orientar programas de melhoramento visando ao desenvolvimento de cultivares superiores. No ano agrícola 2005/2006, foi estabelecido um ensaio, na safra das águas e da seca, em três Estações Experimentais do Iapar, num total de seis ambientes. O delineamento utilizado foi o de blocos ao acaso, com 20 tratamentos e três repetições. As parcelas foram constituídas por duas linhas de 5 m, com espaçamento de 0,5 m entre linhas e com densidade de 15 plantas por metro. Foram efetuadas avaliações para o número médio de dias para florescimento e maturação fisiológica e produtividade de grãos por parcela. As análises de variância individuais e conjuntas para produtividade de grãos revelaram efeitos significativos para genótipos, ambientes e para a interação G x A, em nível de 1 e 5% de probabilidade, revelando que os genótipos comportaramse diferentemente de acordo com os ambientes. As linhagens LPSIA04-103, LPSIA04-104 LPSIA04-106 e LPSIA04-108 destacaram-se por apresentarem precocidade, ou seja, menor número médio de dias para florescimento e maturação fisiológica dos grãos, produtividade de grãos média elevada e ampla adaptabilidade.

We made four crosses between carioca group cultivars that differed in respect to the presence or absence of an orange hilum corona color. The F 2 , F 3 , F 1 BC 11 , F 1 BC 21 , F 2 BC 11 and F 2 BC 21 phenotypic segregations were evaluated with a chi-square test which fitted with the hypothesis that one gene with a dominant allele is responsible for the orange corona color. All generations resulting from the four different crosses showed segregation patterns which agreed with the expected proportions. Our results show that the dominant G allele controls orange corona color in the carioca bean group.

Three crossings among bean cultivars with different growth habit and seed characteristics were analyzed. F1 progenies gave origin to F2, RC1P1F1 and RC1P2F1 generations. Random samples of seeds from F2 generations and parents, F1 and backcrossings were sown during the season 2003/2004. Plant grain yield and seed morphological traits were determined by a sample of 150 plants from F2 generations and 20 plants from parents, F1 and backcrosssings. Genetic effects involved in each crossing were obtained from estimates of genetic components means and genetic and environmental components of phenotypical variance. Results showed that the seed morphological traits were controlled by a complex of genes, with additive effects predominance although dominance effects were present. High and negative correlations among seed length and thickness with grain yield suggested gr...
