Genetic Variances and Interrelationships of Six Traits in a Hybrid Population of Zea mays L.1

C. W. Stuber, R. H. Moll and W. D. Hanson2

Genetic variability and interrelationships of six characters in the cross of two maize populations were investigated. An evaluation of the epistatic components of variation received primary consideration. Design I and II mating schemes were employed in the study. Results for yield indicated that the magnitudes of the additive variance and the dominance variance were similar. Additive variance was found to be larger than dominance variance for ear number, days to tassel, tiller number, plant height, and ear height. Epistatic variability was not detected in the interpopulation variance component analyses for the characters studied. Sizeable genetic interrelationships were indicated between: (1) yield and number of ears; (2) number of ears and number of tillers; (3) days to tassel and plant height; (4) days to tassel and ear height; and (5) plant height and ear height.
