Abstract
The experiment was undertaken during 2014-15 at Division of Fruit Science,
UHS, Bagalkot. The investigation comprised of 11 genotypes to know the variation in
growth, yield and quality parameters among the genotypes. The highest shoot length
(75.34 cm) was recorded in Chenin Blanc at 60 days after back pruning. The
maximum shoot girth (1.61 cm) was recorded in Sauvignon Blanc at 105 days after
pruning. The vigour of the shoot increased with the decreased number of canes per
vine. Chenin Blanc registered the maximum number of leaves per shoot (17.94) at 90
days after pruning and also Chenin Blanc had long period (20.00 days) for panicle
emergence.
The genotype Medika recorded the maximum length of berry (1.64 cm),
diameter of berry (1.59 cm) and mean weight of berry (3.08 g) at different intervals.
The bunch length and weight of 50 berries varied significantly among the treatments.
The maximum bunch length (23.33 cm) was found in Medika. However, Medika had
the highest 50 berry weight (121.53 g) among the genotypes, Sirius was found to be
an early where harvesting was done in 115 days. The maximum number of panicles
per vine (120.44) and the maximum number of bunches per vine (110.44) was
recorded in Grenache Blanc. The genotype Medika recorded the maximum bunch
weight (419.15 g). However, the genotype Tempranillo registered the highest tonnage
(60.88 t/ha) followed by Grenache Blanc (53.98 t/ha). The maximum total soluble
solids (28.4 0B) at 35 days after veraison was recorded in Sirius. However, 42 days
after veraison TSS was maximum (26.280B) in Shiraj which was on par with Sirius.
The best genotypes identified for northern dry zone of Karnataka with respect
to growth, yield and quality parameters are Tempranillo, Grenache Blanc, Medika,
Bianca, Shiraj, Sauvignon Blanc, and Sirius.
