Abstract
Eight desi chickpea genotypes of mid-maturity group were screened by using an open-field screening technique. The genotypes ICC-3137, K-850 and ICC-1403 were found to be more susceptible than the others. More eggs were laid and more larvae were recorded on more susceptible genotypes. A low amount of acidity in the leaf extracts of genotypes was found to be associated with susceptibility to gram pod borer, Heliothis armigera (Hubner).
Résumé
Huit variétés de pois-chiche (type Desi) ont été testées pour leur résistance à Heliothis armigera (Lepid. Noctuidae) en plein champs. Les génotypes ICC 3137, K 850 et ICC 1403 se sont avérés les plus sensibles anx attaques de l’insecte. Les variétés présentant une résistance vis à vis de l’insecte sont caractérisées par des exudations foliaires plus acides que celles des variétés plus sensibles.
