Avocado (Persia americana) is one the most nutritious fruits native of tropical America. In India it was brought during first decade of nineteenth century. A few seedlings of their choice varieties were also occasionally brought from different countries by Missionaries and planted in several parts of humid tropical region of south India and hill stations like Kallar, Palni, Kodaikanal, Yercaud, Coorg etc. As of results lot of variability of avocado is available in these regions. In order to identify elite lines of avocado, several accessions were collected, planted and evaluated at ICAR-IIHR-CHES, Chettalli, Karnataka, India. The growth characteristic of 38 accessions of avocado revealed that the height of the plant ranged from 2.65 to 6.46 m. It was the highest in PA-VII-1 (6.46 m). The plant girth range from 32 to 81 cm it was the highest PA-XVI-1 (81cm) and the lowest in PA-II-2 (32 cm). The accessionsPA-II-3, PA-III-1, PA-IV-1, PA-VII-1, PA-XIII-1, PA-PH-1 were found vigorous growth with plant height of more than 6 meter. The canopy spread was higher (>15.0 m² ) in PA-XII-1 (15.79 m²), PA-XVI-1 (17.78 m²), and PA-PH-1( 17.67). The higher plant volume was recorded in PA-PH-1 ( 91.62 m³ ), PA-XVI-1 (79.50 m³ ) PA-X-3 (53.18 m³) and , PA-XIII-1 (63.04m³) and PA-XVI-4 (57.51).The number of fruits per plant were the highest in PA-XIII-1 (353.3 fruits) and the lowest in PA-VIII-2 (7 fruits). The fruit yield was highest in PA-XIII-1 (149.8kg/plant) followed by PA-III-1 (115.36 kg). The fruit weight ranged from 122g to 871g. The fruit colour of all the accessions was light green at maturity. The pulp colour was light creamish yellow in all the accessions. The fruit shape varied from round to pear shape as the fruit shape index ranged from 0.985 to 1.541. The pulp content was the highest (81.46%) in PA-VII-1. The seed content ranged from 10.25 to 29.34 percent. The total soluble solids ranged from 3.6° Brix (PA-VIII-2) to 12.8°Brix (PA-Nursery-1). The ascorbic acid content ranges from 1 mg (PA-III-4) to 10.6mg/100g (PA-XI-2). Over all the accessions, the accessions PA-III-1, PA-XIII-1, PA-II-1, PA-X-3 were found better with respect to fruit yield and fruit size
