ROOTSTOCK INFLUENCES QUALITY OF “RUBY SEEDLESS” TABLE GRAPE (VITIS VINIFERA L.) IN CENTRAL-NORTHERN MEXICO

Grapes are cultivated in the semiarid region called Comarca Lagunera (Coahuila), located in Northern-Central Mexico, with 244 mm of annual rainfall falling mainly during the summer, and 1900 mm of annual evaporation. (Madero, 1993). Phylloxera (Daktulosphaira vitifoliae), nematodes (Melydogine spp) and cotton root rot (Phymatotrichum omnivorum), have motivated the growers to use resistant rootstocks that may influence fruit quality.
The objective of this work was to evaluate the effects of several rootstocks on the quality of table grape cv.
Ruby Seedless grown in the Comarca Lagunera.
Cluster and berry weight were larger on SO 4 y 5 BB. The best berry colour was observed on SO 4, Dogridge and 99 R. Dogridge, 99 R and SO 4 had higher soluble content.
Grapes from SO4 and 5 BB were firmer and less berry drop was registered on 333 EM and 5 BB, while 99 R and 110R delayed harvest. Less fruit decay was observed on 41 B and 333 EM. Rootstocks SO 4, 5 BB and 99 R induced the best overall quality on “Ruby Seedless” grapes.
