“…High heritability values for this trait were not expected, since, according to Ramalho et al (1993), grain yield in common bean presents quantitative inheritance. However, the magnitude of heritability estimates for grain yield obtained in the present study were similar to those values previously described for grain yield in common bean lines in F 7 generation (Ribeiro et al, 2009;Jost et al, 2014), and F 3:7 (Torga et al, 2010). Thus, despite the fact that it was used parents that had already been selected, and some cultivars have already been grown by farmers in the present study, genetic variability and selection gains ranging from 14.1 (P 3 ) to 25.4% (P 1 ) were obtained for grain yield.…”

“…However, Jost et al (2014) observed lower estimates values for cycle in 272 common bean lines in F 7 generation. The observed differences may be justified by the range of variation observed for cycle in the lines evaluated in different populations, by the experimental design (Faleiro et al, 2002), and by the method of advance of segregating generations (Jost et al, 2014).…”

The objective of this study was to estimate genetic parameters for agronomic and nutritional traits in four common bean populations with biofortified grains for minerals, and to identify the superior population for these traits. Thus, four common bean populations were obtained by controlled crossings between parents contrasting for potassium (P 1 ), phosphorus (P 2 ), zinc (P 3 ) and copper (P 4 ). A total of 40 lines in F 6:8 generation of each population and nine parents were evaluated in two field experiments (rainy season of 2012 and dry season of 2013) in the state of Rio Grande do Sul, Brazil. The studied populations presented genetic variability for cycle, insertion of the first pod, grain yield, and potassium, phosphorus and zinc concentrations in grains. Heritability estimates and selection gain of intermediate and high magnitude were obtained for cycle, insertion of the first pod, grain yield, and potassium concentration in grains in P 2 . In P 4 , insertion of the first pod, grain yield and phosphorus and zinc concentrations in grains presented high heritability and selection gain estimates. From the tested crossings, it is possible to select common bean inbred lines biofortified for potassium, phosphorus and zinc and with high agronomic performance.

“…Erect and less lodged plants are sought by breeders and farmers, enabling mechanical harvesting (MENDES et al, 2009) and providing better grain quality due to lower pod contact with the soil (JOST et al, 2014). SILVA et al (2009b) has observed heritability values of 0.1-0.65 for PA in F 5.7 populations.…”

We aimed to apply genomic information based on SNP (single nucleotide polymorphism) markers for the genetic evaluation of the traits "stay-green" (SG), plant architecture (PA), grain aspect (GA) and grain yield (GY) in common bean RESUMO: Objetivou-se incorporar informações genômicas de marcadores SNP ("single nucleotide polymorphism") na avaliação genética das características "stay-green" (SG), arquitetura de planta (AP), aspecto de grãos (AG) e produtividade de grãos (PG) em feijoeiro-comum via modelos Bayesianos. Estes modelos foram comparados quanto a acurácia de predição e habilidade de estimação da herdabilidade para cada característica. Utilizaram-se informações de 80 cultivares genotipadas para 377 marcadores SNP, cujos efeitos de substituição alélica foram estimados por meio de cinco diferentes modelos Bayesianos: Bayes A (BA), B (BB), C (BC), LASSO (BL) e regressão "ridge" (BRR).Embora as acurácias de predição calculadas por meio de análise de validação cruzada tenham sido similares dentro de cada característica, o modelo BB se destacou para a característica SG, enquanto o modelo BRR foi indicado para as demais. As herdabilidades estimadas para SG, AP, AG e PG foram, respectivamente, 0,61, 0,28, 0,32 e 0,29

“…The identification of new cultivars that meet the expectations of farmers and consumers involves research activities requiring dedication and, above all, continuity (Ramalho and Abreu, 2006). Although main goal of improvement has been increased grain yield, other features have also received the attention of breeders, such as disease resistance; abiotic and biotic stresses; plant architecture; and grain quality (Miklas et al, 2006;Hegay et al, 2013;Terán et al, 2013;Jost et al, 2014).…”

ABSTRACT. This study evaluated the performance and estimated the genetic potential of segregating populations of red bean. Twenty populations of the second cycle of recurrent selection for red bean breeding at Universidade Federal de Viçosa were advanced to the F 5 generation in bulk with selection for grain appearance. Populations plus five controls were evaluated for grain yield in three dry seasons (2004, 2005, and 2007) in a 5 x 5 lattice design with three replications, in four 4-m long rows. In the mean of the three crops, populations formed three distinct groups in which some populations had a clearly superior grain yield. Populations 288RVCI, 291RVCI, 295RVCI, 297RVCI, 300RVCI, and 303RVCI were the most promising. Over generations, segregating populations by the bulk method with selection for grain appearance may have reduced variability in grain yield. The 300RVCI population deserves further attention as it combines variability, high mean, and a high probability of generating above-standard lines.
