Phenotypic Characterization of Common bean (Phaseolus vulgaris L.) Accessions Conserved at the Genetic Resources and Biotechnology Institute: Experimental Investigation

Factors Influencing the Emergence of Heterogeneous Populations of Common Bean (Phaseolus vulgaris L.) and Their Potential for Intercropping

“…The changes affected both genetic composition and phenotypic traits, and can also be influenced by outcrossing, while other bean varieties were grown nearby during the trials, allowing for potential gene flow between experimental and non-experimental plots [ 58 ]. Nevertheless, heterogeneity within the common bean population is a combination of different factors, such as mutations, genetic drifts, environmental conditions affecting outcrossing rates, and different pollinator species with different cross-pollination abilities [ 56 , 58 , 59 , 60 ].…”

“…In particular, the colour of the seed coat is an important characteristic for the selection of the common bean and is usually highly variable. Within accessions, seed coat variability can be caused by mutation and subsequent segregation, and can also be explained by epistasis [ 7 , 25 , 28 , 60 , 75 , 76 ]. The colour of the seed coat is determined by many genes with epistatic interactions that produce primary and secondary colours.…”

Coleta E Conservação De Germoplasmas De Feijão - Comum Do Espírito Santo

“…A caracterização das variedades de feijão-comum foi baseada em grupos morfológicos. Por meio dela ocorre a redução das duplicatas presentes nos bancos de germoplasmas, distinção de materiais vegetais de maior importância e uso consciente dos recursos genéticos (MUSANGO et al, 2016;RIBEIRO et al, 2020).…”
