Evaluation and character association studies on yield and quality parameters of tamarind genotypes

Abstract

The present investigation “Evaluation and character association studies on yield and quality parameters of tamarind genotypes” was carried out during 2017-18 at Forest Research Station (FRS), Govinkovi, Honnali taluk, Davangere district. The experiment was laid out in a randomized block design with three replications and 16 genotypes viz., K-9, NTI-52, K-11, S-7, S-8, S-14, S-3, N-6, D-2, C-4, D-9, NTI-89, D-19, S-6, K-10 and K-12. While, the genotypes differed significantly with respect to total soluble solids (D-9: 22.76 °Brix), titrable acidity (S-8: 11.25%) and sugars content viz., reducing sugar (C-4: 34.06%), non-reducing sugar (D-9: 12.17%) and total sugar (C-4: 46.18%). The results of correlation co-efficient analysis revealed that pod length (cm), pod width (cm), pod weight (g), pulp weight (g), titrable acidity, total sugar, total soluble solids and pH attributes could be effectively used in tamarind improvement programme for selecting genotypes as they show positive association for higher yield.
