ABSTRACT
Screening of groundnut (Arachis hypogaea L.) genotypes against spotted pod borer, Maruca vitrata (Geyer) was conducted during rabi 2015-16 at dryland farm, S.V. Agricultural College, Tirupati. Twenty-five genotypes were screened against the spotted pod borer. Among these Percent infestation of M. vitrata was less in K-9, ICGV-86368, TCGS-1426, CS-19 genotypes and more in K-6, Dharani, Narayani and TCGV-1543. The experimental results indicated that spreading type and short stature groundnut cultivars were tolerant to the M. vitrata incidence. Chlorophyll content and Specific Leaf area, these plant physical parameters showed significant effect on incidence of M. vitrata in groundnut crop. Chlorophyll content was negatively correlated with (r =-0.48) with per cent infestation of M. vitrata at 60 DAS. Specific Leaf area was positively correlated with (r=0.43) with per cent infestation of M. vitrata at 60 DAS and also short stature plants groundnut cultivars were tolerant to M. vitrata incidence.
Key words: Arachis hypogaea, Maruca vitrata, Percent infestation.
