A trial of Flue-Cured Virginia (FCV) hybrid varieties was evaluated for morphogenetic and disease-resistant characteristics during 2019-2020. It was conducted in a randomized complete block design (RCBD) with three replications of seven varieties (PVH-1600, PVH-2275, PVH-2340, PVH-2324, PVH- 2329, SPT-G-28, and K-399). The plant height, leaf dimensions, green leaves, cured leaves weight, nicotine, and reduced sugar contents were examined. Analysis showed highly significant differences (P>0.01) among varieties for examined traits. The maximum number of green leaves (28), was produced by PVH-2324 at first picking, while PVH-1600 showed the maximum number of leaves (22), leaf area (1241cm2), green leaves (29.3 Kg) and cured leaves weights per plot (4.6 Kg). Furthermore, PVH-1600 and K-399 showed the maximum mean values for green leaves (0.97 Kg) and cured leaves (0.227 Kg) weights respectively. The tallest plant was identified as PVH-2324 (136.21 cm). Genotype PVH-2329 revealed the maximum amount of reducing sugar (15.83%) compared to other PVH varieties. Moreover, the highest nicotine (2.91 %) content was found in K-399. From the present study, it is concluded that PVH-1600 and PVH-2329 varieties showed the best performance as compared to other promising hybrids for most of the important parameters under study. Therefore, these genotypes are recommended for future cultivation in the agro-climatic conditions of Mardan.
