Abstract: A survey was conducted in the state of Meghalaya, covering four districts, i.e., East Khasi Hills, RiBhoi, West Jaintia Hills and East Jaintia Hills to ascertain the morphological and biochemical variability in litchi. Significant variations among the genotypes were observed for morphological parameters of fruits. The fruit weight ranged between 15.16 gm to 23.89 gm; fruit length (3.21-3.56 cm); fruit diameter (2.87-3.39 cm); peel weight (2.36-4.12g); aril weight (10.14-16.34 g);aril: seed ratio (2.36- 11.73) and seed weight (1.35-4.32g). A significant variation was also observed for biochemical parameters of fruit. The genotype Umsyiem recorded the highest TSS (20.8±0.95%), total sugar (15.97±0.24%) and ascorbic acid (35.84±1.59 mg 100g-1), while, titratable acidity was maximum in Umniuh Tmar (0.77±0.06%). Therefore, litchi genotypes such as Umsyiem and Nongkhrah may have unique potential for further enrichment of genetic improvement in litchi germplasm.
