Yield related key traits in the selection of super sweetcorn hybrids

Super sweet corn breeding must develop hybrids that fully meet the expectations of market. In this sense, determination keytraits for selection sweetcorn genotypes is a fundamental condition success. The objective work was to identify key traits promising and contrasting super corn. experiments were carried out in Guarapuava (PR), two sowing dates. Seventeen related yield quality ear evaluated. To perform multivariate analysis, data subjected diagnosis multicolinearity, analysis canonical variables, genetic divergence, hierarchical clusters, factor correspondence analysis. Grain yield, dehusked ears, number commercial ears considered identification genotypes. Hybrid D3-20 × D5-41 presented higher averages than others, considering keytraits.
