Screening of some promising pigeonpea genotypes against Maruca vitrata (Geyer)

Sunil Verma, RP Maurya, Ravindra Kumar and Chenesh Patel

The present experiment was conducted to screen thirty one genotypes of pigeonpea with three check cultivars viz., PUSA 992, PA 291 & UPAS 120 for their resistance/tolerance to Maruca vitrata under natural infestation in pesticide free open field during (2015-2016) to isolate sources of resistance to Maruca vitrata and results revealed that when overall mean of the larval population of Maruca vitrata was considered together the minimum larval population (1.65 larvae/5 shoots) was observed on genotype UPAS120 x H82-1 (P3) and maximum 2.78 larvae/5 shoots on genotype H82-1 x PUSA 992 (P5). However, among all the genotypes of pigeonpea the minimum webbing (3.64%) on genotype AL 201 x PUSA 992 (P3) and the highest number of webbing (7.67%) was observed on genotype H82-1 x UPAS 120 (P4).
