The response of Z. mauritiana cultivars Baranasi Karaka, Chhuhara, Dandan, Gola, Ilayachi, Jogia, Kaithali, Katha Phal and Umran to topworking was studied. Scion buds collected from Jhargram, West Bengal, India were topworked on 5-year-old trees of Z. rotundifolia. At 2 months after budding, budding success was 100% in Baranasi Karaka and Kaithali, and 80% in Dandan, Jogia, Katha Phal and Umran. Gola had the highest number of leaves (116). Scion height (155 cm) and girth (10.0 cm) were greatest in Umran. Jogia recorded the highest fruit yield per plant at 7 months after budding (62.1 kg), as well as the highest number of fruits per plant (1600). Fruit weight was highest in Umran (39.2 g). Fruit length and weight were more pronounced in Baranasi Karaka (5.4 and 3.4 cm), Dandan (5.1 and 3.0 cm), Jogia (4.9 and 3.8 cm) and Umran (4.8 and 3.8 cm). Seed weight was lowest (0.6 g) in Ilayachi and highest (1.9 g) in Jogia. Ilayachi fruits registered the greatest total soluble solids (21.8 degrees Brix), total sugar (13.3%), and vitamin C (235.5 mg/100 g pulp) contents. Titratable acidity was greatest in Gola (0.48%), whereas total soluble solids/acidity ratio was highest in Katha Phal (56.9). Pulp consistency was crispy or moderately crispy, except in Gola and Katha Phal in which the pulp was of the melting type. The fruits matured between the 4th week of January and 2nd week of March. Based on ripening period, Baranasi, Karaka, Chhuhara, Dandan, Gola and Jogia were classified as early; Kaithali and Umran as moderately early; and Ilayachi and Katha Phal as late.
