“…The 'Carioca' group experiment had a good precision, with a coefficient of variation below 15 percent; for the black group, the coefficient of variation was between 18.19 and 32.12 percent, representing, respectively, medium and low experimental precision (Carbonell et al, 2010;Pereira et al, 2018). Results of the analysis of variance demonstrated significant effects for genotypes and environments suggesting the presence of genetic variability between bean lines and edaphoclimatic differences between environments, in this order ( Table 1).…”

Low yields of early ‘Carioca’ and black bean varieties are a consequence of instability and low yield adaptability to specific growing environments. The goal of this work was to evaluate the genotype x environment interaction of early ‘Carioca’ and black bean new lines aiming at obtaining genotypes with high grain yield and good adaptability and stability. In (2012), 15 genotypes of the black group were evaluated in Ibimirim, Belém do São Francisco, and Petrolina municipalities, in Pernambuco State, Brazil; and, in (2016), 11 genotypes of early ‘Carioca’ bean were evaluated in Caruaru, Arcoverde, and Araripina municipalities, also in Pernambuco State. The experiment was conducted in a randomized block design with three replicates, and grain yield data were submitted to analysis of variance, in which means were compared by the Tukey’s test and analysis via GGE Biplot. In Arcoverde, the grain yield was greater for all early ‘Carioca’ bean genotypes, whereas, in the environment of Petrolina, there was the worst grain yield in kg ha-1 for all black bean genotypes, individually. The GGE Biplot methodology was found to be efficient in identifying genotypes with good adaptability, stability, and yield. Differences presented by the genotypes for the grain yield trait give the basis to recommend the genotypes and express the possibility of selection for genetic improvement of the species.

“…These facts are related to the objectives of breeding programs in Brazil. For carioca-type beans, breeding programs emphasize seed size (large), shape (oblong), and color (light beige with a light brown stripe), and seed size is inversely related to yield [ 41 , 42 ]. However, large seeds are not important in the black commercial group, so cultivars with smaller seeds and high yield potential have been selected [ 40 ].…”

Morpho-agronomic, biochemical and molecular analysis of genetic diversity in the Mesoamerican common bean panel

et al. 2021

The common bean (Phaseolus vulgaris L.) is of great importance to the food and nutritional security of many populations, and exploitation of the crop’s genetic diversity is essential for the success of breeding programs. 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 clustering analysis generated six groups. AFLP analysis also revealed significant differences among the accessions. There was no correlation between the differences based on genetic markers and those based on morpho-agronomic and biochemical data, which indicates that both datasets are important for elucidating the differences among accessions. The results of the present study indicate great genetic diversity among the evaluated accessions.

“…The procedure was carried out by the single seed descent method (SSD), up to the F 6 generation, when plants were selected. This same generation advancement methodology was also for the development of cultivar UENF 2014 (Pereira et al, 2018). Each F 6 plant originated a Recombinant Inbred Line (RIL), and the RIL number 129 was selected and registered in the Ministry of Agriculture, Livestock, and Supply -MAPA under the name 'UENF Rioparaíba.'…”
