“…Este resultado é de fundamental importância em estudos de divergência genética, pois no processo de escolha dos genitores, além da dissimilaridade entre os genótipos, também deve-se considerar o alto rendimento de grãos para a obtenção de progênies superiores. Resultados divergentes foram relatados por Almeida et al 2011e Glasenapp et al (2014), em que a PRO apresentou pouca influência na discriminação de genótipos de soja tipo grão em estudos de diversidade.…”

The simultaneous evaluation of qualitative and quantitative traits is an excellent tool to estimate the genetic divergence among accessionsof germplasm banks. The present study aimedto characterize and estimatethe genetic divergence among soybean food type accessionsbased on Gower algorithm and identifies promising combination among accessionsevaluated. A total of 64 soybean genotypes were studied, which 60arefood type soybean accessions, twoarecommercial cultivars also for human consumption,and two are grain type commercial cultivars. Three qualitative and seven quantitativetraits were used to estimate the genetic divergence among genotypes. The experiment was carried out in the experimental areaof the Universidade Estadual de Londrina during 2015/2016season, using a randomized complete block design with four repetitions. It was observed the presence of genetic variability to all traits evaluated. Thegrainyield trait was the mostefficientin discriminating theevaluated accessions,while plant height showed lower contribution. The UPGMA method showed the highestcoefficient of cophenetic correlation allowing the formation of six different groups. The crossings AL06 × AL22 and AL07 × AL22 are promising for obtaining superior genotypes destined to the in naturaconsumption and production of soy milk and tofu. The combination AL13 × AL60 is considered favorable for obtaining genotypes destined to natto production. The use of the AL12 and AL13 accessions as parents is advantageous for obtaining genotypes for the production of kuroname.

ABSTRACT. Soybean (Glycine max L.)-breeding programs aim to develop cultivars with high grain yields and high tolerance to Asian soybean rust (Phakopsora pachyrhizi). Considering that the traits targeted for breeding are mainly quantitative in nature, knowledge of associations between traits allows the breeder to formulate indirect selection strategies. In this study, we investigated phenotypic, genotypic, and environmental correlations between the agronomic traits of soybean plants naturally infected with P. pachyrhizi, and identified agronomic traits that would be useful in indirectly selecting soybean genotypes for high yields. The study was conducted on the Capim Branco Farm, Uberlândia, Brazil, with 15 soybean genotypes, which were cultivated in a completely randomized block design with four replications. Fourteen phenotypic traits were evaluated using the GENES software. The phenotypic and genotypic correlations were positive and of a high magnitude between the total number of pods and the number of 17718-17729 (2015) pods with two or three grains, indicating that the total number of pods is a useful trait for the indirect selection of soybean genotypes for high grain yields. Strong environmental correlations were found between plant height at blooming and maturity and grain yield and yield components.

ABSTRACT. In the final phases of new soybean cultivar development, lines are cultivated in several locations across multiple seasons with the intention of identifying and selecting superior genotypes for quantitative traits. In this context, this study aimed to study the genotype-byenvironment interaction for the trait grain yield (kg/ha), and to evaluate the adaptability and stability of early-cycle soybean genotypes using the additive main effects and multiplicative interaction (AMMI) analysis,
