摘要

The present investigation was conducted during 2023–2025 to evaluate the performance and variability of ten genotypes along with the standard cultivar Allison for flowering, vegetative, fruit quality and biochemical traits. Significant differences among genotypes were observed for all studied parameters, indicating substantial genetic variability. UHF-9 recorded the longest flowering duration (24.44 days), whereas Allison produced the highest number of flowers per shoot (42.78). Enhanced vegetative growth was observed in UHF-6, which exhibited maximum leaf area (227.23 cm2), while Allison recorded larger leaf dimensions. Fruit morphological evaluation revealed that Allison produced the longest fruits (91.57 mm) with the highest fruit length/width ratio (1.807), whereas UHF-7 recorded maximum fruit weight (181.58 g) and fruit width (61.58 mm). Superior biochemical quality traits were observed in UHF-3 for total soluble solids (19.19°B), UHF-6 for total sugars (7.55%) and UHF-5 for ascorbic acid (163.70 mg/100 g) and sugar-acid ratio (23.09). Genotypes UHF-7, UHF-8 and UHF-9 exhibited comparatively higher phenol and carotenoid contents, indicating enhanced antioxidant potential. Principal component analysis revealed that the first two principal components contributed 61.32 per cent and 20.68 per cent of the total variation, respectively, accounting for 82.00 per cent of the cumulative variability among genotypes. Hierarchical cluster analysis grouped the genotypes into distinct clusters according to flowering, vegetative, fruit and biochemical traits, demonstrating clear phenotypic divergence. Several genotypes, particularly UHF-5, UHF-6, UHF-7, UHF-8 and UHF-9, exhibited performance comparable or superior to the standard cultivar Allison for important horticultural and nutritional attributes. The findings indicate the potential utility of these genotypes for varietal selection, quality improvement and future breeding programmes.
