Phenotypic and genotypic correlations were examined for four traits in seven populations of maize (Zea mays L.) undergoing recurrent selection. Correlations among grain yield and percentage of grain moisture, root lodging, and stalk lodging were low (I r 1 < 0.3) except for the correlation between g

Efficiency comparisons are made among standard recurrent selection methods and for the same methods modified by the inclusion of haploid and cloning techniques. These comparisons are made with respect to five different gene models representing different levels of heritability and also with respect t
Three methods of recurrent selection using doubled haploids (DH) are compared with the same resources: individual line selection (with one DH line per plant), selection between and within families, and selection index of family and line within family values. It seems that for low heritabilities at t
