Field screening of some open pollinated genotypes of chilli against thrips and yellow mite infestation under new alluvial zone of West Bengal

Arka Samanta, Koushik Sen and Ajay Kumar Sahoo

Twenty two open pollinated genotypes of chilli were screened against infestation of thrips and yellow mite based on percent of plant showing visible symptoms at ‘C’ Block Farm, BCKV, Kalyani, Nadia, West Bengal during 2012-13 and 2013-14. The results of the investigation showed that genotypes 2011/-7 (16.47%), 2011/-6 (17.92%) and 2012/-2 (19.00%) were identified as field tolerant to thrips whereas 2011/-8 (21.33%), 2013/-1 (21.78%) and 2011/-3 (22.01) were found as mostly moderately field tolerant. Chilli germplasms 2011/-7 (15.97%) and 2013/-1 (18.25%) were recorded as field tolerant to yellow mite whereas 2011/-6 (21.55%), 2011/-8 (21.98%) and 2012/-2 (22.43%) were graded as mostly moderately field tolerant. 2011/-9 was identified as the most susceptible genotype to both thrips (33.43%) and yellow mite (38.05%). The results suggest that chilli open pollinated cultivar 2011/-7 was found least affected or tolerant to both thrips and yellow mite and may be utilized in the resistance breeding programme.
