Avocado or butter fruit is a tropical evergreen climacteric fruit scientifically known as Perseaamericana, which belongs to the family Lauraceae. Avocado is a medium-sized, evergreen tree that reaches about 20-30 feet in height with large, green foliage cover. The fruits were pear-shaped and green in color. The present study is focussing on the physical characteristics of the Avocado cultivars, which were grown in Kerala. The cultivars selected for the study include Purple hybrid, Fuerte, Kallar round and Pollock. The parameters analysed included the fruit side, shape, weight, fruit length, seed length, cavity width and cavity length. Pollock had shown the highest fruit length (17.00cm), fruit weight (435.20g), seed length (7.20cm), skin waste (35.93g) and seed weight (50.37g). The highest skin thickness (0.17cm) and cavity length (7.50cm) was noted in Purple hybrid. The pulp yield (86.20g) was found higher in the cv Kallar round.
