Fruit characterization of jackfruit (Artocarpus heterophyllus Lam.) local genotypes under coffee ecosystem of lower pulney hills in Tamil Nadu, India.

Abstract

n experiment was conducted to evaluation of jackfruit (Artocarpus heterophyllus Lam.,) local genotypes under coffee ecosystem of lower pulney hills at Horticultural Research Station, Thadiyankudisai and its adjoining areas, Tamil Nadu Agricultural University, Coimbatore during year 2016-2017 with an objective to characterize the promising local genotypes for commercial cultivation and studies of genetic improvement with jackfruit, five fruits of each of thirty five genotypes were evaluated based on IPGRI, 2000 (Bioversity international) jackfruit descriptor. Fruit characters viz., bearing habit, bearing position, clustering habit, shape, length, diameter, weight, stalk attachment, spine density per 25 cm2, fruit rind weight and flake characters viz., total weight of flakes per fruit, weight of individual flake with seed, weight of individual flake without seed, number of flakes per fruit, flakes: fruit ratio, rind: flakes ratio, flake length, flake width, shape of flake, flake colour. Results were evaluated by descriptive statistics viz., mean, standard deviation, coefficient of variation, standard error of mean. It was concluded that a more variation of fruit character was found under lower pulney hills of Tamil Nadu, it will help to breeder for accounting potential fruit character in future.
