title: Characterization of avocado (Persea americana mill.) varieties of low oil content.
abstract: Several avocado varieties of low oil content (6.73-8.07%) from Venezuela (Booth 1, Booth 7, Ceniap 2, Figueroa, Guacara Morado, Luiz de Queiroz, Princesa, Quebrada Seca, Santa Clara, Santa Cruz, Taylor, and Tonnage) were characterized for pulp oil and moisture; weight (whole fruit, seed, pulp, and peel); length, width, and fruit shape; peel characteristics (roughness, color, and hand peeling); and ripeness time. Oil plus moisture percentages were between 87.62 and 93.71. Pulp percentage of Quebrada Seca was the lowest of the 49 varieties studied, and its seed percentage the highest. Princesa had the highest pulp percentage (76%). Seven varieties were pyriform and five ovate, seven had rough peel and five smooth peel, and four of them had purple peel and the others green. Five varieties were easy to hand peel. Peak ripening of some varieties was at 4-9 days. Princesa is the variety with the highest potential yield with 67944 kg of fruit/ha, 51675 kg of pulp/ha, 3679 kg of oil/ha, and 3016 kg of starch/ha.
