Description
Summary:The genetic variability for haploid regeneration parameters and yield traits, and their relationship were studied using 39 genotypes of hexaploid winter wheat in two separate experiments, realized with the same conditions in a greenhouses. The experimental design was a randomized-complete block design with three replications, each replication consisting of one pot containing three plants per genotype per experiment. The genetic correlations between the different haploid regeneration parameters by anther culture and yield traits were determined from the means of all replications of each gentoype. The mode of association of all the traits was also studied by using the principal component analysis method. Extensive genetic variability was shown for all haploid regeneration parameters and yield traits. Positive and significant correlations (P=0.001) among haploid regeneration parameters and yield traits were observed, but there was no significant positive or negative relationships between these two groups of traits. We conclude that selection for androgenic parameters does not have any negative effect on yield traits and successful selection should be made for haploid regeneration parameters and/or yield traits in crossing programmes.
