Parent selection for intercrossing in food type soybean through multivariate genetic divergence Agronomy
Guerra, Edson Perez; UEL; Destro, Deonisio; UEL; Miranda, Lilian Azevedo; UEL; Montalván, Ricardo; UNIOESTE.
Soybean for human consumption shows high genetic variability in relation to nutritional traits. Genotypes can be crossed to obtain inbreed lines adapted for a region, with high yield and nutritional qualities. In the multivariate analysis, the multiple information of an experiment are combined, based on a complex of variables, to select the best parents with high divergence. One hundred and four genotypes were analyzed for 12 characters of agronomic importance to select food type soybean parents, using the multivariate analysis based on Mahalanobis generalized distance (D2) and on Tocher’s classification method. Seven groups were formed trough clustering. The traits that most contributed to this classification were plant height at flowering (19.50%) and...
