The varieties are Zinfandel, Cabernet Sauvignon, Shiraz, Ruby Red, Pusa Navrang, Bangalore Blue, Athens and Gulabi are the red varieties whereas, Symphony, Chenin Blanc, Sauvignon Blanc, Thompson Seedless and Italia are the white varieties. Observations recorded on growth parameters revealed that based on the pruning weight, varieties were classified as vigorous (Athens, Shiraz, Ruby Red); moderately vigorous (Italia, Bangalore Blue, Gulabi, Pusa Navrang, Sauvignon Blanc, Symphony and Chenin Blanc); less vigorous (Zinfandel, Cabernet Sauvignon and Thompson Seedless). On the basis of bud break requirement, varieties were grouped as early (Pusa Navrang, Bangalore Blue, Chenin Blanc and Gulabi), mid-season (Sauvignon Blanc, Symphony, Shiraz, Zinfandel, Italia and Cabernet Sauvignon) and late season varieties (Ruby Red, Thompson Seedless and Athens). These results signify the scope of high potential of growing wine varieties under Southern Zone of Telangana.
