Última Comparison between the SPD and the SPDS methods for segregating generation advancement in soybean BABT Destro,Deonisio; Bizeti,Henrique Stoco; Garcia,Leandro Anderlin; Fonseca,Inês Cristina de Batista; Montalván,Ricardo; Miglioranza,Édison. The purpose of this work was to compare the SPD (Single Pod Descent) and SPDS (Single Pod Descent with Selection) methods for segregating generation advancement in soybean breeding. Sixteen populations derived from crosses among Japanese and adapted Brazilian soybean were used. The traits, number of days to flowering (NDF) and to maturity (NDM), plant height at flowering (PHF) and at maturity (PHM), and individual plant yield (IPY) were assessed. The populations obtained by SPDS showed values close to the variation in the populations obtained by SPD. Regression through the origin showed that both methods were equivalent for NDM in the F3 generation and for NDF in the F4 generation. For all other trait/generation combinations, SPDS yielded superior means.... Tipo: Info:eu-repo/semantics/article Palavras-chave: Glycine max; Breeding methods; Food type soybean.

This study aimed to establish the phenotypic correlations among several soybean traits with grain yield in direct and indirect effects using path analysis, and to compare alternative methods for minimizing the adverse effects of multicollinearity in estimating path coefficients. The experiment was conducted in greenhouse in a randomized complete block design with four replications. Nine soybean genotypes belonging to three seed size categories were used. The correlation studies and the path analysis showed that the seed size was not important for increased yield. The number of nodes and plant height at maturity showed significant correlation with grain yield. Using the least square methodology, the results obtained by path analysis under multicollinearity...
