ABSTRACT

The different cultivars of sapota namely Cricket Ball, Singapore, CO-1, CO-2, PKM-1, PKM-2, PKM-3, DHS-1, DHS-2, Kalipatti and Pala took about 6-9 months from fruit set to harvestable maturity and followed double sigmoid curve in terms of fruit weight. The number of days required from fruit set to harvest differed significantly with the varieties. The cv. DHS-2 recorded the highest number of days (263.46) to attain harvestable maturity followed by cv. DHS-1 (258.00) and Cricket Ball (257.93) while the lowest was observed in cv. PKM-1 (189.33). The fruit weight was maximum in cv. Cricket Ball (123.20 g) followed by cv. DHS-1 (122.40 g) while it was minimum in cv. Pala (32.09 g) and PKM-1 (46.18 g). The pattern of fruit development in terms of fresh weight of the fruit followed double sigmoid growth curve and maximum increase in fruit weight was observed between 150- 210 days after set.
