“…This criterion is repeated in the genotypes CNPA 2012-55, CNPA 2012-58, CNPA 2012-62 and CNPA 2012, selected by the genetic means free of interaction (μ + gˆ).This fact indicates that these genotypes presented adaptability and genotypic stability between the three environments analyzed, in addition to having high length of fibers, i.e., the maintenance of this trait across the different environments. These results corroborate those obtained by Maia et al (2009), Regitano Neto et al (2013 and Torres et al (2016), who verified the maintenance of the ranking of cashew clones, rice genotypes and cowpea, respectively, by genotypic value of methods for the mean of years (μ + gˆ), HMGV, RPGV and HMRPGV, attributing these results to genotypic correlation across sites (r gloc ), which was positive and of similar magnitude to those of study.…”

“…Thus, HMGV, RPGV and HMRPGV have been used as measures for the interpretation of genotypic stability and adaptability of crops, such as common bean (Carbonell et al 2007), sugarcane (Bastos et al 2007), cashew (Maia et al 2009), eucalyptus , rice (Regitano Neto et al 2013), and cowpea (Torres et al 2015, Torres et al 2016). However, they have not been used for breeding purposes in cotton.…”

Abstract:In cotton breeding programs, it is necessary to identify genotypes with predictable behavior on the length of fibers, and which are responsive to environmental variations, in specific or broad conditions. The aim of this study was to employ the methodology of mixed models for simultaneous selection of cotton genotypes with greater length of fibers, adaptability and stability. It was evaluated 36 lines in three trials located in Apodi (2013and 2014) and Santa Helena (2013 CNPA 2012-55, CNPA 2012-58, CNPA 2012-62 and CNPA 2012 can be grown in all tested environments, since they gather greater length of fibers, stability and adaptability. in a randomized block design with two replications. Genetic parameters were estimated by the restricted maximum likelihood/best linear unbiased predictor method (REML/BLUP) and the selection was based on the method of harmonic mean of the relative performance of genetic values.

“…In this context, an alternative to studying the adaptability and stability of genotypes is the method of harmonic mean relative performance of genotypic values (HMRPGV), advocated by Resende (2004). Although this method has been applied to various cultures, its use in value and cultivation trials with cowpea remain restricted (SANTOS et al, 2016;TORRES et al 2015;TORRES et al, 2016).…”

-The restricted maximum likelihood/best linear unbiased prediction (REML/BLUP) mixed model method has been used to study the effects of genotype by environment interaction (G x E) in various crops including cowpea. This work aimed to analyze the G x E interaction via mixed models to identify cowpea genotypes that meet high adaptability, stability and productivity of pods and green grains when grown under Mossoró, Rio Grande do Norte State conditions. Crop value and use were evaluated in two growing seasons, using randomized complete blocks design with 23 genotypes and four replications. The genetic parameters were estimated by the REML/BLUP procedure and selection was based on the harmonic mean of the relative performance of genetic values (HMRPGV). Agreement between the HMGV, relative performance of genotypic values (RPGV) and HMRPGV statistics, provided genotype discrimination. Furthermore, the HMRPGV results enabled the simultaneous selection of superior genotypes for productivity, adaptability and stability. For the productivities of pods and green grains, the most notable genotypes were the cultivars BRS Xiquexique and BRS Aracê, and the line MNC05-835B-15, which showed a high productivity of grains, adaptability and stability, and could be grown in the two growing seasons considered in the study.Keywords: Adaptability.

INTERAÇÃO GENÓTIPOS x AMBIENTES EM GENÓTIPOS DE FEIJÃO-CAUPI VERDE ANALISADA VIA MODELOS MISTOSRESUMO -A metodologia de modelos mistos REML/BLUP tem sido empregada para estudar os efeitos da interação genótipos x ambientes (G x E) em várias culturas, inclusive em feijão-caupi. O objetivo deste trabalho foi analisar a interação genótipos por ambientes em feijão-caupi via modelos mistos e identificar genótipos que reúnam alta adaptabilidade, estabilidade e produtividade de vagens e grãos verdes nas condições de Mossoró, RN. Os genótipos foram avaliados em ensaios de valor de cultivo e uso conduzidos em duas épocas de cultivo, sob delineamento experimental de blocos completos casualizados, com 23 genótipos e quatro repetições. Os parâmetros genéticos foram estimados via procedimento REML/BLUP, e a seleção baseou-se no método da média harmônica do desempenho relativo dos valores genéticos (MHPRVG). Houve concordância entre as estatísticas MHVG, PRVG e MHPRVG na discriminação dos genótipos, sendo que esta última possibilitou a seleção simultânea de genótipos superiores em produtividade, adaptabilidade e estabilidade. Para as produtividades de vagens e grãos verdes os genótipos de maior destaque foram as cultivares BRS Xiquexique, BRS Aracê e a linhagem MNC05-835B-15 que reuniram alta produtividade de grãos, adaptabilidade e estabilidade, podendo ser cultivados nas duas épocas de cultivo consideradas no estudo.

ABSTRACT. 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 selecting common bean genotypes with high yield, adaptability, and stability for the Cerrado/Pantanal ecotone region in Brazil. We evaluated 11 common bean genotypes in three trials A likelihood ratio test detected a significant interaction between genotype x year, contributing 54% to the total phenotypic variation in grain yield. The three genotypes selected by the joint analysis of genotypic values in all years (Carioca Precoce, BRS Notável, and CNFC 15875) were the same as those recommended by the HMRPGV method. Using the centroid method, genotypes BRS Notável and CNFC 15875 were considered ideal genotypes based on their high stability to unfavorable environments and high responsiveness to environmental improvement. We identified a high association between the methods of adaptability and stability used in this study. However, the use of centroid method provided a more accurate and precise recommendation of the behavior of the evaluated genotypes.
