Role of rootstocks in yield and quality of grapes (Vitis vinifera) under semi-arid tropics of India: a review

Abstract

Grape (Vitis vinifera L.) cultivation is gaining importance under tropical and sub-tropical conditions of India by adapting advance crop techniques. The problems of detoriated soil, poor and shortage of water conditions affecting the grape production on own rooted vines, which results into use of rootstock in grape cultivation. There are large number of rootstocks available in grape cultivation according to different production constraints. Rootstock not only helps in withstanding vineyard in adverse climatic conditions but also help in improving yield and quality of. The rootstock Dogridge became popular among the grape growers due to its capabilities of overcoming abiotic stresses and better stionic combination. The rootstock suitable for one variety in a given location may not be suitable for the same variety on other location. Hence, choice of rootstock is varied among the different cultivars. In a view of better yield and quality of grapes, there should have better stock-scion compatibility which imparts high vigour into the scion.
