Abstract

Abstract

Ten, eight-line sets of dent maize inbreds (Zea mays L.) were tested for seed resistance to maize weevil (Sitophilus zeamais Motschulsky) in a design II experiment. The genetic variability was evaluated for maternal, cytoplasmic, and endosperm genotype sources. Dominance effects were important for seed resistance among sources segregating for maternal and endosperm genotypes. Most of the additive variation originated from maternal tissues, while cytoplasmic effects were unimportant. A procedure of recurrent selection within two breeding populations, with concomitant attention to crossbred performance, is suggested.
