摘要

超甜玉米育种必须开发出完全符合市场预期的杂交品种。从这个意义上说,确定甜玉米基因型选择的关键性状是育种成功的基本条件。这项工作的目的是确定关键性状,以选择有前途和对比的超甜玉米基因型。试验在瓜拉普瓦(PR)两个播期进行。评价了与穗产量和品质有关的17个性状。为了进行多变量分析,我们对数据进行了多重共线性诊断、典型变量分析、遗传差异、层次聚类、因素分析和典型对应分析。籽粒产量、去皮穗产量和商品穗数被认为是鉴定有潜力的超甜玉米基因型的关键性状。考虑到产量相关关键性状,杂交种D3-20 × D5-41的平均值高于其他品种。

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