Abstract
An experiment was conducted at Regional Agricultural Research Station, Ishurdi, Pabna, Bangladesh during rabi 2003-04 to find out the influence of pod morphological traits (like pods trichome length and density, pod wall thickness, pod length, breadth, area and number of pods per plant) on pod borer resistance in chickpea. All the traits showed significant influence on pod borer resistance. Pod trichomes length and density showed negative correlation to pod borer damage in chickpea i.e., genotypes having longer pod trichomes and or more pubescent pods received lower pod borer damage. Relationship study between pod wall thickness and pod borer damage indicated negative correlation which suggested the chickpea genotypes having thicker pod wall received lower pod borer damage. Pod length, breadth and area of respective genotypes showed significant effect in resistance mechanism against pod borer damage. Study showed a negative correlation between the pod length, breadth and area to pod borer damage. The pods having higher length, breadth and area were less preferred by the pod borer. Number of pods per plant also affected pod borer incidence. The study determined a positive correlation between the number of pods per plant and pod borer damage. The genotype having higher pod bearing potentiality received higher pod borer damage
