Abstract

The present study was conducted at ICAR- National Research Centre for Grapes, Pune during fruiting season of 2022-2023 and 2023-24. The variety Sauvignon Blanc stood out among white wine varieties, showing superior growth parameters like pruned biomass (0.853 Kg/vine), shoot length (102.56 cm), internodal length (7.89 cm), number of leaves (25.61/fruiting shoot) and yield parameter like number of bunches (60.50/vine). Minimum days taken to bud sprout (8.50 days) and higher shoot diameter (7.94 mm) was recorded in Charak-2. Higher leaf area was recorded in Riesling (3532.27 cm2/fruiting shoot) and Muscat Petit (150.21 cm2/leaf) varieties. Higher chlorophyll content was recorded in White Muscat (22.28 mg/ml). Higher number of berries (157.56/bunch) recorded in Trebbiano. Yield-related metrics like bunch weight (183.20 g) higher in Muscat Petit, 100 berry weight (186.80 g) in Riesling, yield in Marsanne (8.53 kg/vine and 10.32 MT/acre) for pooled mean basis.
