“…For lodging, the scores ranged from 1 (upright plants) to 9 (prostrate plants, i.e., all plants fallen, touching the ground) (Ciat, 1987) were assigned. The general adaptation score was determined as described by Ribeiro et al (2010), receiving score 1 (superior genotype) to the upright plants, with great number of pods per plant and no symptom of disease in the pods; and score 9 (inferior genotype) to all prostrate plants, with long internodes, few pods per plant and high severity of disease symptoms in pods.…”

“…Upright plant architecture in the common bean can be visually evaluated by the use of score scales, such as lodging (Mendes et al, 2011;Pereira et al, 2012;Jost et al, 2013;Soltani et al, 2016;Ribeiro et al, 2018a), plant growth habit (Silva et al, 2009), plant architecture (Acquaah et al, 1991;da Cunha et al, 2005;de Lima et al, 2012;Silva et al, 2013;Pires et al, 2014), and general adaptation score (Ribeiro et al, 2010;Ribeiro et al, 2018a). Although score scales are widely used in common bean breeding programs, it should be considered that such assessments depend on the evaluator's experience and usually present low repeatability.…”

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 traits, and to select superior common bean lines based on a selection index. Four experiments were carried out in different years and growing seasons at low altitude (95 m above sea level) in southern Brazil. These experiments were composed of 17 carioca and black bean inbred lines, which are representative of the most widely produced and consumed common bean classes in Brazil. Upright plant architecture was assessed by 12 characters, and the resulting data were subjected to individual and joint analyses of variance, correlation, and selection index (rank sum). A significant effect for genotype and/or genotype x environment interaction was observed for all traits, except for the length of the first internode and hypocotyl diameter. Most plant architecture traits were correlated, indicating that it is possible to reduce the number of traits that need to be evaluated. Grain yield was negatively correlated with the lengths of ©FUNPEC-RP www.funpecrp.com.br Genetics and Molecular Research 18 (2): gmr18323 N.D. Ribeiro et al. 2the fourth (r = -0.574) and fifth internodes (r = -0.641). General adaptation score, insertion of the first pod, and lengths of the fourth and fifth internodes were efficient to characterize upright plant architecture in the common bean. Indirect selection by the shortest length of the fourth and fifth internodes was efficient to increase grain yield. The genotypes LP 11-117, SM 0312, BRS Valente, and Guapo Brilhante were selected based on a rank sum index. These genotypes present upright plant architecture and high grain yield, which is a common bean ideotype suitable for cultivation at low altitude in southern Brazil.

“…Segundo Ribeiro et al (2010) a seleção indireta nos componentes primários da produção de grãos proporciona a identificação de genótipos superiores. O conhecimento do interrelacionamento entre caracteres é de grande interesse do melhoramento de plantas, e a importância da correlação entre caracteres reside no fato, de se poder avaliar o quanto da alteração de um caráter pode afetar os demais caracteres (SILVA et al, 2009), e assim auxiliar na seleção de genótipos mais produtivos.…”

“…Similar methodologies, still less diffused in perennial species, have been applied successfully in agronomic cultivars, usually based on visual identification of plants with superior characters, which requires a higher ability of the evaluator (CUNHA et al, 2005;MENEZES JUNIOR et al, 2008;RIBEIRO et al, 2010). In this way, the use of visual scores in selection programs and its correlation with the productivity linked to biological characters like gender, provenances, progenies and morphotypes, may be an excellent alternative to support the selection process of erva-mate progenies and clones.…”

Commercial biomass production is one of the main indicators for selecting erva-mate (Ilex paraguariensis) progenies and clones. Traditional techniques to obtain such information depend on the harvesting of trees and there are some limitations involved, such as high cost and reduced convenience. Thus, in our research we evaluated the efficiency of indirect methods through commercial biomass estimation and score of productivity according to the different provenances, gender and morphotypes. In a provenances and progenies trial installed in 1997, two methodologies of visual analysis were evaluated in August 2015 (two years after the last harvest). For that reason, five expert evaluators determined, for each plant, an estimate of the commercial biomass (kg), and a grade, based on a score of productivity (0-10). In order to assess the productivity using traditional techniques, all plants were pruned and their commercial biomass (leaves and fine branches smaller than 7 mm diameter) were harvested and weighed (kg . plant -1 ). The evaluations were performed in a randomized-block experiment with five repetitions, seven different provenances and 126 progenies, totaling 5,292 evaluated plants. The methods utilized were effective to estimate the commercial biomass. The evaluators showed accuracy, expressing efficiently the largest productivity obtained when comparing the means of provenances, plants gender and morphotypes. The highest correlations were observed in the general analysis of the means, and the estimation of commercial biomass was considered the best methodology for estimating the commercial biomass assessed in adult erva-mate plants. METODOLOGIA PARA AVALIAÇÃO EXPEDITA E INDIRETA DA PRODUTIVIDADE COMERCIAL DE ERVA-MATERESUMO: A produção de biomassa comercial é uns dos principais indicadores para seleção de progênies e clones de erva-mate. Técnicas tradicionais para se obter tais informações dependem da colheita das árvores e apresentam, dentre outras limitações, elevado custo e reduzida praticidade. Assim, objetivou-se avaliar a eficiência de métodos indiretos, por meio de estimativa de biomassa comercial e escore de produtividade em função de diferentes procedências, sexo e morfotipos. Em um teste de progênies e procedências instalado em 1997, foram avaliadas em agosto de 2015 (dois anos após a última colheita) duas metodologias de análise visual. Para tanto, participaram cinco avaliadores treinados que determinaram, para cada planta, uma estimativa de biomassa comercial (kg), e uma nota, com base em um escore de produtividade (0-10). Para avaliação da produtividade pelas técnicas tradicionais, todas as plantas foram podadas e tiveram sua biomassa comercial (folhas e ramos finos menores de 7 mm de diâmetro) colhida e avaliada por meio de pesagem (Kg . planta -1 ). As avaliações foram realizadas em experimento instalado em blocos ao acaso, com cinco repetições, sete procedências e 126 progênies, totalizando 5292 plantas avaliadas. Os métodos avaliados foram eficientes na estimativa da biomassa comerc...
