Abstract

Sixteen grape varieties were evaluated at Punjab Agricultural University, Ludhiana for their growth attributes, bunch characters, physical and chemical properties with the aim to identify most suitable variety for northern region having greater yield potential and improved fruit quality. Bud initiation was recorded earliest, i.e. 39 days after pruning in variety Beauty Seedless, while the variety A 47-1 took maximum time to bud burst (48 days after pruning). The highest fruitfulness (84.73 %) and number of bunches (62.75/ vine) were recorded in Punjab Purple (H-516). The minimum number of bunches (15.75/vine) was recorded in E 12-2. The significantly higher bunch weight (232.8 g) was recorded in H-144 whereas, it was minimum in E 12-2 (51.6 g). Highest TSS was found in Himrod (18.0 %), while the minimum TSS was recorded in H- 27 (12.4 %). Highest acid content was recorded in H-27 (0.75 %) and the lowest acidity percent was measured in Chardonnay, Merlot, Beauty Seedless, Cardinal and Himrod (0.48 % each). The early ripening variety was Beauty Seedless (1st June) while Tannat and A 47-1 were found late ripen varieties. Based on growth and fruiting characteristics, the varieties Punjab Purple (H-516) and H-144 were found to be most promising under North Indian conditions.
