Abstract : The fruits were harvested and then graded into 3 specific gravity grades viz. 1.0 (Gr.I), 1.0 to 1.02 (Gr.II) and > 1.02 (Gr.III). The fruits of Gr.I were the biggest and those of Gr. III the smallest. The fruits were ripened under ambient conditions (29-35°C and 75-65% RH) and evaluated for various storage attributes up to 11 days. Gr.III fruits ripened earliest (within 5 days) and their shelf life was less, compared with fruits of Gr.I and II. Gr.I fruits ripened with better quality and shelf life and retained some marketability even after 11 days of storage. The development of carotenoids and the rate of starch depletion was slow in Gr.I fruits and so was the senescence, compared with Gr.II and III fruits.
