摘要: The objective of this work was to select maize families derived from backcrossing between the composite NAP Corn Stunt (donor parent) and inbreed lines (recurrent parents), as grain yield resistance corn stunt, evaluate efficiency use molecular markers in phenotypic evaluation for selection genotypes with high yield. One hundred were evaluated five environmental conditions 2009/2010 crop season. We selected RC1F2 families, which combine present recurrent parents stunt donor parent. agronomic performance were: L228-3-324-S, L228-3-237-R, L228-3-109-R, indicated crosses flint heterotic group; L3-422-R L3-586-R, dent group. For selecting yield, marker-assisted is not efficient recovery parent genotype, when compared evaluation.
