| Abstract:
Eighteen grape varieties planted in 1997 were evaluated for their performance at Regional Research Station, PAU Bathinda (Latitude 30°17’ N; longitude 74°58’ E; and elevation 211 m amsl) with respect to yield, bunch and berry characteristics, and fruit quality. The early maturing varieties required lesser heat units (890.1 to 1051.1 day °C) as compared to the late maturing varieties (1020.1–1491.7 days °C). The varieties Angur Early and Banqui Abyad consumed minimum heat units (890.10 day °C) to reach the ripening stage. The variety Arka Shyam consumed highest heat units (1491.7 day °C) from fruit setting to ripening and this was on par with Arka Hans and Arkavati. Perlette consumed 1051.10 day °C heat units. Banqui Abyad required minimum number of days from full bloom to ripening (DFFB; 51.20) that were on par with Angur Early, Khalili, Sindhu, Delight, Beauty Seedless and Perlette. The variety Perlette produced the highest fruit yield (25.07 kg/vine) and was followed by Beauty Seedless (19.90 kg/vine). In respect to the bunch breadth and length, Beauty seedless, Delight and Perlette were found to be good performers. The highest berry weight was found in Cardinal (4.80 g) and it was on par with Banqui Abyad. The highest TSS was found in the variety Delight (18.23%) and it was on par with Beauty Seedless, Khalili, Unknown, Banqui Abyad, Black Muscat, Black Prince, Arkavati, Arka Shyam and Shadipur Local. The cultivars, Perlette and Beauty Seedless were on par with respect to the TSS and acidity. The cultivar Perlette outshined all the other cultivars as far as the fruit yield is considered. | |
