Abstract


A study was conducted in the Department of Fruit Science, College of Horticulture, Vellanikkara during 2018-2019 to characterize the accessions of avocado maintained at Regional Agricultural Research Station, Ambalavayal. Twenty-five trees were selected and studied for different fruit and seed characters based on the IPGRI crop descriptor for Persea spp. Wide variability was observed for fruit and seed characters. Various fruit shapes such as clavate, ellipsoid, narrowly obovate, obovate and pyriform were observed. Variability was also observed in seed shape such as base flattened and apex conical, base flattened and apex rounded, broadly ovate, cordiform and ovate. Highest fruit weight was recorded in AV-7 (152.7g) and highest seed weight in AV-17 (100.1g).
