Online published on 20 December, 2024. Abstract The results demonstrate considerable variability in both leaf angles and mean leaf injury scores across the cultivars. Shaktiman-4 displayed the widest leaf angle at 60.25 degrees, while RHM-2 exhibited the narrowest angle at 46.00 degrees. In terms of mean leaf injury scores, RHM-2 recorded the highest susceptibility at 7.42, whereas Deep Jwala displayed notable resistance with a score of 2.65. Lakshmi, identified as resistant, showcased a leaf angle of 54.50 degrees and a mean leaf injury score of 3.70, underscoring its dual significance in plant morphology and stress resilience. New Cross variants displayed intriguing variations, with New Cross (72 × 70) recording both a high leaf angle (63.50 degrees) and a relatively low mean leaf injury score (3.57).
