Nodal segments of strawberry cv. Chandler were collected from the field and surface sterilization of the explants was carried out using various levels of decontaminants as different treatments viz. sodium hypochlorite (NaClO) 0.5% for 7, 5 and 3 min and mercuric chloride (Hg Cl2) 0.1% for 5 min, 3 min and 3 min 10 sec. The explants were excised and cultured for 3 weeks on the initiation medium supplemented with various levels of BAP (0.5, 1, 1.5 and 2mg/l) and its combination with GA (0.5 and 1mg/l). Sub culturing was done and finally ischolar_maining was initiated on the medium supplemented with various levels of IBA (0.5, 1, 1.5 and 2mg/l) for 4 weeks. The results obtained indicated that, among the decontaminants, treatment of explants with Hg Cl2 0.1% for 3 min 10 sec resulted in the minimum contamination and browning of explants. Further, maximum shoot proliferation percentage, shoots per explant and minimum number of days to shoot initiation was observed when explants were cultured on MS medium supplemented with 1.5 mg/l BAP over other concentrations of either BAP or in combination with GA. However, the maximum length of shoots was obtained in medium supplemented with 1.5 mg/l BAP + 0.5 mg/l GA. While, medium supplemented with 0.5 mg/l IBA supported highest percentage of ischolar_maining, the highest number of ischolar_mains, maximum ischolar_main length of microcuttings and minimum number of days to ischolar_main initiation were observed in medium supplemented with 1mg/l of IBA.Keywords

This study aimed at evaluating newly developed hybrids and recently introduced cultivars of French grapes grown in mild tropics of South India for quality wine production. Wines produced from French grapes, viz., Cabernet Sauvignon, Shiraz, Pinot Noir, Sauvignon Blanc, Chenin Blanc and Ugni Blanc scored 15.0 -16.8 in the Davis Score Card for organoleptic analysis. Wines from red Hybrid 18/10 possessed phenolic content of 2097mg/l, had a brilliant colour and sensory score of 13.1. Hybrid 23/2 gave good quality white, dry table wines with a sensory score of 13.4.Keywords
