    Significant correlation in linkage signals from genome-wide scans of schizophrenia and schizotypy

    Prior family and adoption studies have suggested a genetic relationship between schizophrenia and schizotypy. However, this has never been verified using linkage methods. We therefore attempted to test for a c...

    Variation in the ribosomal DNA intergenic spacer of a maize population mass-selected for high grain yield

    Variation in the intergenic spacer of ribosomal DNA (rDNA) was detected among individual plants of the open-pollinated maize variety ‘Hays Golden’ and populations derived from this variety. rDNA intergenic spa...

    Predicted and realized grain yield responses to full-sib family selection in CIMMYT maize (Zea mays L.) populations

    The maize (Zea mays L.) improvement program of the International Maize and Wheat Improvement Center (CIMMYT) develops broad-based maize populations and, until recently, improved all of them through full-sib famil...

    Comparisons of maize populations for aluminum tolerance in nutrient solution

    The original Brazilian maize (Zea mays L.) base population ‘Composto Amplo’ and a fourth cycle of selection from ‘Composto Amplo’ were compared with the Hays Golden vareity. Nebraska B Synthetic. Corn Belt x Braz...

    Evaluation of inbred maize lines for aluminum tolerance in nutrient solution

    Maize (Zea mays L.) inbred lines were grown in nutrient solution with different levels of Al and P to study their genetic variability for Al tolerance. Plant measurements for determining inbred line responses to ...

    Inheritance of aluminum tolerance in maize

    The inheritance of Al tolerance in maize (Zea mays L.) was studied in nutrient solution. Analysis of relative seminal root lengths of six generations (P1, P2, F1, F2, BC1, and BC2) derived from crosses between to...

    Heterosis among populations of maize (Zea mays L.) with different levels of exotic germplasm

    Thirteen maize (Zea mays L.) populations including five adapted, five adapted x exotic, two composites of adapted and exotic, and one exotic selected for adaptability were crossed in a diallel mating system. The ...

    Allozyme polymorphisms within and among open-pollinated and adapted exotic populations of maize

    Twelve U.S. Corn Belt open-pollinated and five adapted exotic populations of maize (Zea mays L.) were assayed for allozyme (allele) variation at 13 enzyme marker loci. Extensive allozyme variability was observed ...

    Comparison of full and half-sib reciprocal recurrent selection

    Full and half-sib reciprocal recurrent selection (RRS) were compared algebraically and with computer simulation. The relative performance of the two schemes depended on the selection intensity and the environm...
