Abstract : Ten fruits for each of 28 cultivars were harvested at two stages of maturity (green-ripe and full maturity) and evaluated for internal fruit breakdown (IFB). IFB incidence was minimized in fruits harvested green-ripe in terms of marketable fruits, with the exception of Edward, Gomera-1 and Irwin, significant differences were found between the two maturities for the same cultivar. With the exception of Edward, Gomera-1 and Irwin, and to a lesser extent, Valencia Pride, Mabroka, Ah Pingh and Heidi, full maturity harvesting was seriously detrimental for the majority of the cultivars. In terms of the mean level of IFB, significant differences were found between the two maturities for the same cultivar. Significant differences were also observed among cultivars, with a continuous variation in IFB appearing when the fruits were harvested at full maturity. As seen in marketable fruits, cultivars showing the lowest levels of IFB injury generally coincided with those indicated above as producing higher percentages of commercially acceptable fruits.
