Abstract
Varietal resistance is an effective pest control strategy, if used in combination with other control measures, taking this the present experiment was conducted at Philip Morris Pak. Ltd formally known as Lakson Tobacco Company Limited Mardan Khyber Pakhtunkhwa during 2006-2007; to investigate the growth and yield parameters and comparative natural resistance against tobacco budworm, for this purpose four tobacco genotypes comprising Speight G-28, NC- 606, K-399 and RGH-4 were tested. The experiment was laid out in Randomized complete block (RCB) design with 4 replications and 5 treatments including check, results revealed that for each cultivar statistical differences were observed and recorded for parameters i.e. damaged plants (%), plant height (cm), number of leaves per plant, leaf area (cm²), yield per hectare (kg), Grade index (%) that were at par for RGH-4 followed by Speight G-28 and K-399 in comparison with NC-606. We concluded from this experiment that genotypes RGH-4 and Speight G-28 were recorded comparatively more resistant against the pest and for other traits so in case of unavailability of RGH-4 the Speight G-28 may also be cultivated for good performance in terms of comparatively resistant cultivar against tobacco budworm.
