Abstract

Forty-nine genotypes of chickpea (Cicer aritinum L.) were evaluated in two winter seasons in Duhok during seasons 2014/2015 and 2015/2016 using Randomize Complete Block Design (RCBD) with three replications in order to estimate genetic variability, correlation and heritability. The results exhibited highly significant effect for interaction between seasons and genotypes on 1000-seed weight, plant height, seed yield, days to flowering and maturity, first pod height, and number of pods/plant. The genotype Flipo 7-223c was superior in the most characters followed by genotypes Flipi 7-245c and Flipo 7-31c. The highest genetic coefficient was observed for number of pods/plant (23.95), moderate for seed yield (11.50 gm) and low for the other characters, while the phenotypic coefficient was high for number of pods/plant (28.68) and moderate for 1000-seeds weight, seed yield and first pod height with values of (11.15 gm, 18.17 gm and 13.00 cm) respectively, also the result revealed that, the heritability in broad sense was high for plant height and moderate for 1000-seeds weight and number of pods/plant with a value of 0.69 for both characters .Low heritability was observed for the other characters. The genetic advance was high for number of pods/plant (35.19) and moderate for 1000-seeds weight (13.57 gm) and (12.81gm) for seed yield. For this study, the characters were having moderate to low heritability coupled in high to low genetic advance as percentage of mean indicated that, the role of non-additive genetic components control this character, so using selection is ineffective to improve these characters.

Key words: Genetic variability, Correlation, Chickpea heritability, Genetic advance.
