Screening of different germplasm of chickpea against pulse beetle (Callosobruchus chinensis L.) and its relationship with quality parameters

Abstract

Ten germplasm of stored chickpea were tested for their resistance against pulse beetle, Callosobruchus chinensis L. under laboratory conditions during the year 2013 and 2014 at the Department of Entomology, Narendra Deva University of Agriculture and Technology, Kumarganj-Faizabad. In above germplasm, the per cent seed moisture, per cent seed infestation, per cent seed germination and chemical composition of the seed were evaluated on the basis of their storage period before and after three months of storage. The results revealed that none of the germplasm was completely immune to the attack of C. chinensis. However, their response varied statistically significantly. Per cent infestation being main index of resistance, germplasm DCP 92-3 was found significantly highly tolerant and BG-256 least tolerant followed by NDG11-5, NDGK 98-8, NDG 93-1, NDG 97-1, IPC 2004-52, BG-362, BG 50-28 and NDG 12-1, were significantly susceptible. The co-efficient of correlation between per cent infestation with per cent moisture content, protein content and fat content was positive significantly, and per cent germination was negative significant.

Biology and Morphometrics of Pulse Beetle, Callosobruchus chinensis L. on Chickpea

“…The duration of various life stages also varies among the different types of pulses studied by Mehta and Negi (2020) as well as different varieties describing the varietal preference of the pulse beetle studied by Singh et al (2016). Jaiswal et al (2019) and Kamble et al (2016).…”

Relative Susceptibility of Chickpea Varieties to Callosobruchus chinensis L. (Coleoptera: Bruchidae) and Appraisal of its Quantitative and Qualitative Losses

“…It is commonly known as gram dhora or pulse beetle and causes substantial quantitative and qualitative losses (Aslam et al, 2006;Upadhyay et al, 2011). Its infestation results in reduced germination capacity, grain weight and seed value (Singh et al, 2016). It is a destructive pest of stored pulses in Africa and Asia (Kiradoo and Srivastava, 2010).…”
