Influences of various rootstocks on yield and quality of wine grape varieties (Vitis vinifera L)

Abstract

The investigation was carried out at Instructional- cum- Research Farm of Department of Horticulture, College of Agriculture, Latur during the year 2010-2011. There were significant differences found in yield attributes viz; number of berries per bunch, weight of berry, number of bunches per vine, weight of bunch, yield kg per vine and yield Mt per hectare were maximum in Syrah-524 grafted on 110 R, quality attributes viz; Total Soluble Solids (0Brix), Acidity (%), juice (%), pH of Juice, Syrah -524 grafted on 110 R was found to be non significant in TSS and pH. Ugni Blanc-380 grafted on 110 R showed non significant in acidity. Viogneir Noir-15 grafted on 1103 P was showed significant in juice per cent.
