Abstract
This study conducted to know the susceptibility of three genotypes of Chickpea (Cicer arietinum L.), Gab3, Spinal and Morocco (Marrakesh) to Helicoverpa peltigera Denis& Schiffermuller, (Lepidoptera: Noctuidae) under field conditions in Nineveh covernerate, the results showed that there were significant differences among the means percentage of plant infestion which was 89.66% for Spinal genotype in the first week of May, and 48.18% for Gab 3 genotype in the fourth week of May, and also the results showed thatا Spinal genotype was more susceptible which reached the highest total mean of plant infestion 76.42% while the lowest total mean reached 61.45% in Gab 3 genotype, and the sampling date has significant differences was the means percentage of plant infestion which was77.16% in the third week among of May and the lowest total mean 61.33% in the second week. There were significant among between the means percentage of pod damage which was 40.91% in Morocco genotype in the second week of May, while reach 14.12% in Gab 3genotype in the last week of May, and the genotype of chickpea has significant effects in total percentage means of pod damage which was 32.30% in Morocco genotype and 24.22% in Gab 3 genotype, and the sampling date has significant effects among the total means percentage of pod damage which was 31.08% in the first week of May but the lowest total mean was 24.26% in last week of the sampling. Also the results showed that there were significant effects among the means of pod weight , and seed weight, volume and pod husk thickness according to the chickpea genotype, the highest mean of pod weight , and size were 1.603gm and 3.35cm3 respectively for Morocco genotype while the lowest means of pod weight , and size were 0.786gm and 1.200cm3 respectively for Spinal genotype, also the highest mean of seed weight and size were, was 1.376gm and 1.00cm3 for Morocco genotype , while lowest means of seed weight , was 0.624gm and 0.66cm3 for Gab 3 genotype , the highest mean of pod husk thickness were 0.316mm. for Gab3 genotype while lowest means of pod husk thickness was 0.160mm. for Morocco genotype. Also the results showed that there were significant differences among the means of nitrogen percentages of chickpea genotypes which was 40.69% for Gab 3 genotype while it was 15.06% for Spinal genotype, but there were no significant differences among the means of phosphor and potassium percentage of chickpea genotypes.
