The present investigation was carried out at the Hoskote Forest Station, Bengaluru Rural District, India. The plant material consisted of Twenty eight accessions which were planted in June, 1998. The observations for the present investigation were recorded during 2018-19 and 2019-20 fruiting seasons. The RCBD design was followed to control variability and improve the accuracy of experimental results.
The accessions were evaluated for different morphological traits viz. bearing habit, fruit characteristics such as shape, pulp colour, length, width, thickness, weight, pulp weight per fruit, seed weight per fruit, number of seeds per fruit, shell weight per fruit, vein weight per fruit and their corresponding percentages (seed, pulp, fibre and shell). It also explores phytochemical traits in tamarind pulp, including titratable acidity (%), TSS (°Brix), pH, ascorbic acid (mg/100 g) and tartaric acid (%). Nutrient content in tamarind pulp, specifically manganese, potassium, calcium and magnesium was also analysed. The correlation co-efficient among all the possible morpho and phytochemical trait combinations were analyzed statistically.
Significant differences among the tamarind accessions were noted, STAM-28 and HSTAM-40 recorded the highest values in all the growth, pod and yield characters. Correlation analysis revealed that Fruit weight was highly significant and showed association with fibre weight, thickness of fruit, pulp weight, fruit width, fruit length, shell weight, tartaric acid and titratable acidity content of pulp. This suggests that there is potential to select traits that can help identify superior genotypes/accessions in terms of both quality and yield of tamarind.
