Abstract:
Fifty two avocado accessions maintained at ICAR – IIHR – Central Horticultural Experiment Station, Hirehalli were studied for their genetic diversity. Characterization was done based on tree and leaf characters using the plant descriptors outlined in IPGRI publication, Descriptors for Avocado. The study revealed that avocado accessions showed wide variability for the characters under study. With respect to tree characters most the accessions exhibited circular tree shape, rough trunk surface, irregular branch distribution and acute crotch angle of main branch to trunk. Among the leaf characters under study oval leaf shape, intermediate leaf apex shape, acute leaf base shape and entire leaf margin were found to be dominant.
