Biochemical evaluation of local genotypes of jackfruit (Artocarpus heterophyllus Lam.) in Pudukkotai District

Abstract

The research was conducted during 2015-2016 in eight villages of Pudukkotai district of Tamil Nadu, India with an objective to evaluate the local seedling genotypes of jackfruit using biochemical traits. Totally 40 genotypes were evaluated. The coefficient of variation for fruit biochemical characters such as TSS (18.15 %), total sugars (24.70 %), reducing sugars (22.64), non-reducing sugars (27.50 %), titrable acidity (34.83 %), ascorbic acid content (32.81 %) and carotene content (41.86 %) showed considerable variations. Among the biochemical parameters, carotene content (41.86 %) exhibited high variation among the evaluated genotypes. Based on the yield per tree and biochemical parameters, the genotypes namely AH-11, AH-13, and AH-35 were found promising. These identified genotypes can be good donor in hybridization programme to evolve the superior varieties for crop improvement.
