Evaluation of variability in Some Local Genotypes of Maize (Zea mays L) under rain fed at Damazin Research Station, Blue Nile State

摘要

Estimation of the genetic variability among 18 local genotypes of Maize (Zea mays L) was recorded. In a genotype X tester fashion, 16 genotypes were crossed with low testers. All the 32 F_(1) genotype and their 18 parents were sown for two seasons (2007/08 and 2008/09), in summer (Autum). The results in season 2007/08 indicated highly significant differences for Number of leaves / plant while significant for the--- character--- day's to 50% tasselling, stem diameter, leaf area, Cob bareness% Cob diameter, Cob weight, yield/ plant and yield (t/ha). On the other hands in season 2008/09, a highly significant differences were shown for three characters (day's to 50% tasselling, Cob diameter and yield t/ha), while significant for six characters (stem diameter, Number of leaves/Plant, leaf area, Cob bareness%, Cob weight and yield per plant).
