Studies on shoot growth and berry development in different genotypes of grape

Abstract

Shoot growth and berry development pattern in different genotypes of grape was studied in five promising hybrids with five parental cultivars in a replicated trial. The five cultivars used as female or male parents were; Anab-e-Shahi, Angurb Kalan, Black Champa, Thompson Seedless and Queen of the Vineyard. Hybrids were studied against their parents in respect of vine growth parameters, yield attributes and quality components. Shoot length and leaf number per shoot at 90 and 105 days after budbreak during the fruiting season were positively correlated with total soluble solids. Fresh weight of berries at 30, 45, 60, 75 and 90 days after fruit set was positively correlated with Brix-yield/15 berries and 50 berries weight at harvest. All the five hybrids had more shoot length and leaf number than their parents. The study has shown that Anab-e-Shahi hybrids E-5/12 and E-9/3 and Black Champa hybrids E-29/4 were improvements over their respective parents with respect to yield and quality attributes, while Black Champa hybrid E-29/4 were improvements over its parents with respect to yield and quality attributes, while Black Champa hybrid E-29/5 and Angurb Kalan hybrid F-5/4 were improvements over their respective parents with respect to quality.
