Importance of agronomic traits in the individual selection process in sugarcane determined using the logistic regression Agronomy
Brasileiro, Bruno Portela; Peternelli, Luiz Alexandre; Silveira, Luís Cláudio Inácio; Barbosa, Márcio Henrique Pereira.
The aim of this study was to evaluate the relative importance of agronomic traits during the individual selection in sugarcane (Saccharum spp.), as well as evaluate the potential for using logistic regression and decision trees in identifying the best genotypes. A total of 7,719 seedlings of 128 half-sib families were evaluated in the first test phase (T1) and 659 clones were selected for the second (T2). Logistic regression was applied in both populations (T1 and T2). The number of stalks, bud prominence and length of the internode were the most important traits in selection the T1. Plant vigour, stalk diameter and stalk height were the most important traits in selection the T2. There were 174 individuals selected by the mass selection method in T1 and...
