Evaluation of some forage maize (Zea mays L.) genotypes for some Growth and yield Characters

Abstract

This experiment was conducted in the experimental farm of the Sudan University of Science and Technology, College Agricultural Studies, shambat during the winter season 2017-2018, to evaluate ten genotypes of forage maize (Zea mays). The experiment was laid out in randomized complete block design (RCBD) with three replications. The studied growth and yield characters included plant height (cm), stem diameter (cm), number of leaves, leaf area (cm2), dry weight (K/ha) and fresh weight (K/ha). Phonotypic and genotypic variances and heritability values were measured. The results showed significant variances for all the studied characters. The highest values of phenotypic variance (3743.7) and genotypic variance (0.17) were obtained by Leaf area and Number of leaves, respectively. The highest value of heritability (0.33) for was obtained by dry weight. The genotype H1 scored the highest values of dry weights and the genotype MK1 scored the highest values of fresh weight.
