Materials were conducted ear-per-row during the first inbreeding generations and later using a balanced composites. Several single-crosses amongst developed inbreds were practiced. Oil content, protein content, starch content and kernels density were measured at the lab through a non-destructive assay using a NIR device model Tekator Infratec 1227. Measurements were carried out on samples of 49 elite inbreds and F2 kernels taken from 82 precommercial single-cross hybrids developed using them. These represents and important advance in the obtention of quality maize germoplasm as the correlation between oil and protein usually is non-significant or even may adopt negatives values.
