SELEÇÃO RECORRENTE FENOTÍPICA VISANDO À OBTENÇÃO DE UMA VARIEDADE SINTÉTICA DE MILHO (ZEA MAYS L.).

Abstract

Corn (Zea mays) is a major crop species grown in the world, and its production can be found in areas with soil conditions and very contrasting weather. This fact is crucial for the establishment of genetic breeding programs. The present research aimed to produce a synthetic variety of maize from the interbreeding of cultivars available in the market, as well as to evaluate the agronomic performance observed during the phenotypic recurrent selection procedure. It was observed that the selected population showed a great homogeneity, creating a uniform population, which is required for the cultivar registration. The evaluation of the agronomic performance of genotypes contributed to the generation of basic knowledge required to process development of this new variety.
