Avocado (Persea americana Mill.) is found scattered throughout Mizoram. Although, the agro-climatic condition of Mizoram is found suitable for the growth and development, there are some specific areas where the performance of Avocado is found better in terms of yield and production. In order to assess the genetic diversity of locally grown avocado in Mizoram, present study was carried out during 2015–17 to find out the elite types of avocado from home gardens of Mizoram, north-east India. The mature fruits were collected and analyzed for morpho-physico-biochemical traits. The individual fruit weight ranged from 230.39–411.49 g, fruit length from 83.25–125.33 mm, diameter from 71.29–92.41 mm, volume from 213.47–399.67 cc; pulp weight from 152.30–267.97 g, peel weight from 37.45–67.64 g, pulp-peel ratio from 2.96–5.47, pulp thickness from 12.22–19.52 cm, peel thickness from 0.14–0.32 cm, seed length from 34.43–52.93 mm, seed weight from 29.95–129.26 g, moisture content from 82.64–65.73%, TSS from 6.21–8.63%, acidity from 0.140–0.299%, ascorbic acid from 9.80–18.34 mg/100 g, total sugars from 1.88–2.96%, reducing sugar from 1.05–1.86%, non-reducing sugar from 0.78–1.49%, sugar:acid ratio from 7.34–21.47 and TSS:acid ratio from 25.45–62.77. Out of all the germplasms studied in the present study, HAMP-MZU-AVS-1, HAMP-MZU-AVS-18 and HAMP-MZU-AVS-21 were found superior in all the parameters. Hence, HAMP-MZU-AVS-1, HAMP-MZU-AVS-18 and HAMP-MZU-AVS-21 could be considered as elite types and they can be used by the breeders to develop new cultivars.
