“…The genotypes were ranked by the WAAS values, and the lowest was considered the (Pereira et al, 2009a). A weight equal to three and to two was used for WAASP and WAAS, respectively (Pontes Júnior et al, 2016;Torga et al, 2016), allowing the assessment of adaptability and stability simultaneously; the yield and WAAS data were transformed to the same scale.…”

The objective of this work was to evaluate the interaction between genotypes and environments for grain yield of common bean (Phaseolus vulgaris) lines and cultivars with potential for use in family farming systems. Data from value for cultivation and use tests, carried out in 20 environments in the state of Goiás, Brazil, were analyzed in two cycles (2007/2008 and 2009/2010) in the dry, rainy, and winter crop seasons. Each test consisted of 15 genotypes from the carioca, purple, and rosinha common bean commercial groups. The experimental design was randomized complete block, with three replicates. The methodologies used to test the stability and adaptability of the genotypes were the one of Lin & Binns, of Cruz, the additive main effects and multiplicative interaction model (AMMI) to calculate the weighted average of absolute scores and productivity (WAASP), and the GGE biplot graphical analysis. The productive performance of the common bean lines and cultivars is affected by genotype x environment interaction. The methodologies adopted allow the selection of cultivars for cropping, and of cultivars and lines for use as parents in order to obtain segregating populations for selection in a family farming system.

“…In plant breeding, the F 2 to F 6 generations are critical phases for selection and evaluation (Ahmad et al, 2017;Pontes Júnior et al, 2016;Yadav et al, 2021). Variance and heritability are mostly assessed in F 2 to F 6 generations to predict the response of the selected population (Hakim & Suyamto, 2017;Oliveira Silva et al, 2021).…”

Introduction. Segregated populations can show the fluctuating performance of one generation to another. This can sometimes confuse plant breeders in interpreting the observed phenomena and determining the selection methods that need to be chosen. Objective. To analyze the performance and yield components of several tomato (Solanum lycopersicum) populations using the pedigree method in lowland environments, Bogor, West Java, Indonesia. Materials and methods. This study was conducted in December 2018–April 2019, at the Experimental Garden of Bogor Agricultural University, Tajur II (207 meters above sea level), Bogor, West Java, Indonesia. Four generations generated from 99D×Tora were used in the study, i.e. 200 plants of F2 generation and 100 plants of each of F3, F5, and F6 generations, respectively. Results. The results showed that the population variance in terms of yield and yield components and heritability were lower in the later generation compared with the earlier generation. Increase in the mean value was observed in F3 generation, but decreased in F5 and F6 generations in all observed characters. It could be caused by fixation as the result of the elimination of epistasis genes that played a role in the environmental stress. Conclusion. Pedigree selection at early generation was not suitable in the lowland. It is suggested to evaluate bulk or single seed descent methods, as those methods were able to maintain population variance up to later generations.

“…Common (dry, edible) bean ( Phaseolus vulgaris ) is one of the main crops grown and consumed in Brazil, representing the main source of protein and dietary fiber of plant origin with high nutritional value (FAO, 2020); it constitutes part of the daily diet of millions of people in the world, especially low‐income families (Messina, 2014; Pontes Júnior et al., 2016). Among the diverse nutrients that make up the bean grain, iron and zinc appear in considerable amounts (Pereira et al., 2014).…”

The aim of common bean (Phaseolus vulgaris) breeding has always been to increase agronomic quality. Recently, the nutritional quality of the grain has been gaining importance. The aim of this study was to estimate genetic parameters for traits related to nutritional and agronomic quality and to select lines for an assessment stage in multiple environments and/or for use as new parents. Initially, 37 lines were evaluated in three environments for nine agronomic and nutritional traits. Of these lines, 15 stood out and were assessed in another five environments. The mixed model (restricted maximum likelihood-best linear unbiased prediction) procedure and multivariate analysis were adopted for processing the phenotypic data. There was genetic variability among the lines assessed for all the traits. The heritability estimates for the agronomic traits ranged from 29% for plant architecture to 94% for reaction to anthracnose. Heritability estimates for the nutritional traits were 77% for grain iron concentration and 79% for zinc concentration. Multivariate analysis, based on all the traits and on all the environments (eight), identified three groups of lines and allowed selection of the lines CNFC 18092, CNFC 18097, CNFC 18114, and BRS Sublime to carry out new crosses, for they showed specific superiority for some traits and the possibility of greater genetic diversity in the populations. The lines CNFC 18091, CNFC 18092, and CNFC 18106 were selected for assessment in experiments in multiple environments because they combine high agronomic and nutritional quality. INTRODUCTIONCommon (dry, edible) bean (Phaseolus vulgaris) is one of the main crops grown and consumed in Brazil, representing the Abbreviations: 100SW, 100-seed weight; ALS, reaction to angular leaf spot; AN, reaction to anthracnose; ARC, plant architecture; BLUP, best linear unbiased prediction; CFe, concentration of iron in the grain; CZn, concentration of zinc in the grain; GA, grain appearance; LOD, plant lodging; REML, restricted maximum likelihood.
