Common bean ideotype; Genetic variability; Pearson correlation; Phaseolus vulgaris; Rank sum index

The development of common bean cultivars with upright plant architecture and high grain yield meets the needs of bean growers by facilitating culture management and mechanized harvest. The objectives of this study were to evaluate whether Mesoamerican common bean lines differ for upright plant architecture traits and grain yield, analyze correlations between these ... more

Conservation; Genetic variability; Harvesting; ISSR

Maytenus truncata (Celastraceae) is a plant species widely used in the treatment of ulcers and tumors. Despite the intensive harvest of native specimens in the State of Bahia, northeastern Brazil, there is no information about the genetic variability or structure of this species. Therefore, the goal of this study was to estimate the genetic diversity and population structure of ... more

Clithon retropictum; Conservation; Endangered species; Genetic variability; Microsatellite loci

The neritid species Clithon retropictum (Gastropoda), an oviparous snail, is distributed in freshwater and brackish water in southern Korea, south-east Japan, southern China and Taiwan. This species is listed as a class II endangered species in Korea because of its decreasing population size. It has led to an increase in the need for genetic information about this ... more

Genetic dissimilarity; Genetic purity; Microsatellite markers; Mixture of cultivars; Phaseolus vulgaris; Simple sequence repeat

The aim of this study was to evaluate genetic divergence in the ‘Carioca’ (beige with brown stripes) common bean cultivar used by different institutions and in 16 other common bean cultivars used in the Rede Cooperativa de Pesquisa de Feijão (Cooperative Network of Common Bean Research), by using simple sequence repeats associated with agronomic traits that are highly distributed in the common ... more

Genetic component; Heritability; Phaseolus vulgaris; Plant breeding; Primary component

The primary components of common bean (Phaseolus vulgaris) grain yield (W) are the number of pods (X), the number of grains per pod (Y), and the weight of the grains (Z). In 1964, Grafius suggested using geometry in plant breeding; W corresponds to the volume of a parallelepiped with three axes, X, Y, and Z. Because the cube is the largest parallelepiped by volume, maximum yield ... more

Centroid method; HMRPGV method; Phaseolus vulgaris

The common bean, Phaseolus vulgaris, is predominantly grown on small farms and lacks accurate genotype recommendations for specific micro-regions in Brazil. This contributes to a low national average yield. The aim of this study was to use the methods of the harmonic mean of the relative performance of genetic values (HMRPGV) and the centroid, for ... more

AMMI; Annicchiarico; Genotype x environment interactions; Phaseolus vulgaris

The aim of this study was to evaluate the phenotypic stability and specific and broad adaptability of common black bean genotypes for the Central and Center-South regions of Brazil by using the Annicchiarico and AMMI (weighted average of absolute scores: WAAS, and weighted average of absolute scores and productivity: WAASP) methodologies. We carried out 69 trials, ... more

Gain from selection; Heritability; Phaseolus vulgaris; Simultaneous selection

Slow seed coat darkening is desirable in common bean cultivars and genetic parameters are important to define breeding strategies. The aims of this study were to estimate genetic parameters for plant architecture, grain yield, grain size, and seed-coat darkening in common bean; identify any genetic association among these traits; and select lines that associate ... more

Common bean cultivars; Cycle stability; Flowering stability; Grain yield; Phaseolus vulgaris; Plant architecture

The objective of this study was to select common bean cultivars based on their stability for flowering, cycle, insertion of the first pod, grain yield, and high agronomic performance. Twenty experiments were carried out between 2000 and 2014, during two growing seasons, in Rio Grande do Sul, Brazil. The Eberhart and Russel, and Lin and Binns methods, as well as the ... more

Common bacterial blight; Genetic diversity; Partial diallers; Phaseolus vulgaris; REP-PCR

The common bacterial blight, caused by Xanthomonas axonopodis pv. phaseoli (Xap) and X. fuscans subsp. fuscans (Xff), is one of the most important dry bean diseases of bacterial etiology. The present work aimed to study the genetic structure among and within populations, and also identify the pathogenic variability of Xap and Xff isolates evaluating the horizontal ... more
