Abstract
An experiment was conducted on “Identification of Elite Tamarind (Tamarindusindica L.) Accessions and Optimisation of Season and Growing Conditions for Maximising Success of Softwood Grafts” during 2018-19 and 2019-20 at Department ofHorticulture, College of Agriculture, UAS, GKVK, Bengaluru and Hosakote Forest Station, Department of Forest, Government of Karnataka, Bengaluru Rural District. The experiment was laid out in a Randomized Complete Block Design with three replications
and fifty accessions. In the present study, the genotypes showed variation in terms of shape of fruit, morphometric characters, phytochemical characters and nutrient content. Significantly higher values were recorded with respect to weight of fruit (GKTAM-18:
35.61 g), length of fruit (HSTAM-28: 21.36 cm), weight of pulp (GKTAM-18: 18.94 g), pulp percentage (GKTAM-1: 55.79 %), fibre percentage (HSTAM-40: 29.40 %), titrable acidity (GKTAM-19:16.89 %), tartaric acid percentage (HSTAM-28:12.15 %), potassium
percentage (GKTAM-1: 24.18 %), manganese percentage (HSTAM48: 3.29 %) and ascorbic acid content (GKTAM-19: 11.27 mg/100g). Correlation studies indicated thatweight of fruit was significantly and positively associated with weight of fibre, thickness
of fruit, weight of pulp, width of fruit, length of fruit, shell weight, tartaric acid and titrable acidity contents of pulp. Softwood grafting studies indicated most graft success (83.23 %) and survival percentage (96.01 %) during the month of March (M3) under Mist
chamber (C4) condition. Therefore, GKTAM-1, GKTAM-18 and HSTAM-28 genotypes were found to be most promising and can be used either for further evaluation or selection as a commercial variety or as genetic source in tamarind improvement programme.
