H. aPrediction and inheritance of prolific expression in maize hybrids.h[electronic resource] c1981 aInbred lines maize (Zea mays L.) were classified as prolific (mostly twoeared), semi-prolific (one- and two-eared plants mixed), and non-prolific (mostly one-eared) on the basis of previous data. Twenty-four single cross and five double-cross hybrid combinations among nine inbreds were compared for expression of prolificacy and seven flowering traits to evaluate the correspondence of inbred classification and prolific expression in hybrids. The criteria used to classify inbreds for prolific potential were the degree of synchronization of silk emergence of the top two earshoots and the frequency of ear development on plants with synchronous silking. These criteria were adequate to predict the kind of prolific expression of most hybrids. The hypothesis was tested that differences between prolific and non-prolific genotypes are affected by two loci with major effects. This hypothesis was rejected on the basis of significant Chi-square tests. However, the hypothesis was accepted that the frequency of second ears on plants with synchronous shoots is affected by segregation for a single major locus. aEspiga aFertilidade aMilho aZea Mays aEars per plant aMaize aProlificacy aProlificidade1 aMOTTO, M.1 aTOLEDO, J.
