Depressão causada pela endogamia em seis variedades de milho (Zea mays L) opaco-2
Keywords:
capacidade combinatória, produção agrícola, variedade brasileira, milho híbrido, depressão endogâmicaAbstract
The inbreeding depression in 6 varieties of opaque-2 corn was evaluated. For each variety, an experiment was carried out in a simple lattice design which included about 100 S; progenies produced by selfing and 4 to 8 treatments consisting of the original variety.
