TRIFONOVA, D. and H. HRISTOV, 2007. Comparative study of the affinity between the Pepinierka vine rootstock and the Chardonnay variety. Bulg. J. Agric. Sci., 13: 259-264
The affinity between the Pepinierka vine rootstock, Bulgarian selection [(Berlandieri x Riparia Kober 5 BB) x Rupestris Marten III-102D)] and the Chardonnay variety was studied. The Chardonnay variety is used for producing high quality white wines. The vine rootstocks Berlandieri x Riparia SO4, Shasla x Berlandieri 41B and Ferkal were used for comparison. The study was carried out during the period 1992-1996 under the soil and climatic conditions of Pleven region.
The values of the studied trait average for the period were higher in grafting the Chardonnay variety on the Pepinierka rootstock. Comparatively high and constant yield of first-class vine planting material was achieved in grafting on the rootstocks SO4 and Ferkal. The results obtained in grafting on the 41B rootstock, used as control, were unsatisfactory.
