Role of morphological characters offering resistance/ susceptibility of pigeonpea genotypes to pod borer complex

Abstract

SUMMARY :Investigation on "Studies on morphological and biochemical basis of resistance against pod borer complex in pigeonpea (Cajanus cajan L.)" was conducted, at the Research cum Instructional Farm of Indira Gandhi Krishi Vishwavidyalaya, Raipur, Chhattisgarh during Kharif -Rabi 2012-13 and 2013-14, respectively.In the genotype screening against pod borer complex viz. M. vitrata, H. armigera and M. obtusa, it was found that the germplasm ICP 6996 showed minimum larval population, minimum pod damage, minimum grain damage, least pest susceptibility rating and gave maximum yield. The second least susceptible germplasm was How to cite this article : Rana, Navneet, Ganguli, Jayalaxmi, Agale, Sandip and Joshi, Bhupesh (2017).

The Morphological and Biochemical Components of Resistance in Field Bean against Pod Borers

“…But in the present study, it was found that pod width did not have any significant effect on pod borer damage. Rana et al, (2017) also reported that pod wall thickness and pod trichome density are negatively correlated with pod damage in pigeon pea. Moudgal et al, (2008), Salimath et al, (2008 and Sunitha et al, (2008) also reported that trichome density on pods found to offer resistance against pod borers.…”
