Screening of certain gram genotypes against Callosobruchus chinensis L. (Coleoptera:Bruchidae)
First Online 20-08-2016|
Chickpea (Cicer arietinum L.), is an important pulse food. During storage this commodity is severely attacked by pulse beetle Callosobruchus chinensis L. (Coleoptera: Bruchidae) and losses in quantity and nutritional quality. Research studies on relative resistance of 8 chickpea genotypes to the attack of C. Chinensis during storage were carried out. The maximum number of eggs laid on genotypes ICCV-07301 (34.35) whole minimum numbers of eggs (17.3) were laid on genotypes ICCV-990126. Significantly higher weight loss (24.98%) was noticed SG-98310 which was followed by SG-950226 (16.64 per cent). Least weight loss (5.78 per cent) was observed in SG-97311 closely followed by SG-98004 (6.36%).. The highest per cent infestation was observed in ICCV-08303 (91.66) and the lowest per cent infestation was observed in ICC-920412 (71.66%) closely followed by ICCV-990126(73.33%). The developmental period was recorded longer on deshi genotypes than kabuli genotypes. After 60 days of infestation the protein content increased by 30.03 per cent in kabuli genotypes and by 48.37 per cent in deshi genotypes.
