Millsp.] Genotypes against Major Insect Pests UR - http://dx.doi.org/10.22207/JPAM.10.4.71 JF - Journal of Pure and Applied Microbiology SN - 0973-7510 PB - Journal of Pure and Applied Microbiology N2 - Ten promising short duration genotypes of pigeonpea were screened under field conditions for two years (2013-15) to identify sources of resistance against pod borers. On the basis of per cent pod damage and Pest Susceptibility Rating (PSR) index, genotypes PUSA-2012-1, PA 409, PA 406, AL1747 were found to be least susceptible (PSR= 4 to 5) while two genotypes, AL 1790 and AL 1770 were ascertained highly susceptible against pod borers having damage rating of 8 over the susceptible check cultivar (Manak). Phenol and flavonoid content present in the pod wall of all the test genotypes/cultivars were also estimated. Highest phenol and flavonoid content was recorded from PUSA-2012-1 while the lowest content was obtained from the genotype AL 1790. Correlation studies made with these biochemical constituents revealed a significant and negative association of pod damage (%) with phenol (r = -0.896**) and flavonoid (r = -0.872**) content in pod walls. Thus the genotypes having higher content of phenols and flavonoids in their pod walls offered resistance against pod borer complex.
