Evaluation of Resistance in Different Chickpea Strains to Callosobruchus chinensis Linnaeus (Coleoptera:Bruchidae) under Laboratory Conditions
To evaluate resistance of seven strains of chickpea against Callosobruchus chinensis, three tests (confinement, free choice and antixenosis) were conducted in the postgraduate laboratory of the Department of Entomology, University of Arid Agriculture Rawalpindi during the years 1997-1999. Randomised Complete Block Design with four replications was used in all the tests. The cotton strains of chickpea namely NCS 96002, NCS 950004, NCS 950012, 92CC-076, 92CC-079, NCS 950183 NCS 960003 and one variety, Paidar-91 were collected from Pulses Section of National Agricultural Research Centre Islamabad. In all the tests, the variety Paidar-91 was used as check/standard, being commercial variety in Potohar region. It was concluded that the chickpea strain NCS-960003 was found to be partially resistant in all the three tests when compared with the standard and NCS-950012 and 92CC-079 were turned out to be be partially resistant to susceptible. NCS-96002 was turned out to be partially susceptible to susceptible. NCS-960183, NCS-950004 and 92CC-076 did not differ much from the standard (Paidar-91).
