Description The litchi (Litchi chinensis Sonn.) is an important evergreen sub-tropical fruit tree specific
to climatic requirement for 'its production. Litchi possesses a narrow genetic base for various agrom
ophol ogical traits. Continuous vegetative propagation of commercial cultivars has further
narrowed down the genetic base resulting in the .restricted period of availability of fruits in the market.
Cultivars have been classified on the basis of economic traits in China and on the basis of growth
and flowering pattern in India (Arora et al. 1996; Singh, 1998). Rai and Vishal Nath (2001) reported
a total of 51 genotypes being augmented from different litchi growing regions and maintained at
HARP, Ranchi. Xuequin (1995) reported 20-25 main litchi types possessing characters of larger fruit size,
small stone, thick and free aril of good quality with good flavor having canning quality from south
China. However, cultivar synonymy does exit due to the insufficient information on i:;haracterization
for different fruit morphological traits and delineation of the characters in its original name. Only few
cultivars and be distinguished based on their fruits characters and maturity period. which creates confusion in identifying the suitable cultivar for any specific region. Keeping this in view, a study was carried out to characterize the different litchi genotypes on the basis of physico-chemical characteristics of fruit under the Chotanagpur plateau region of eastern India
Utchi has narrow genetic base owing to greater use of asexual propagation. Cultivar
synonymy on the basis of local nomenclature causes confusion in identifying a genotype
for any specific purpose. There fore, 17 genotypes under study have been characterized
on the basis of fruit shape index (FSI), specific gravity, seed shape index (SS/), flatness of
seed, number of protuberances/cm' and other physico-chemica/ characters of fruit. The
cultivars China, Purbi and Bombaiya-11 found to have elongated fruit shape whereas
Bedana, Swarna Roopa, Trikolia and Shahi posses roundish fruit shape. Regarding pulp
%, the cultivars Bedana, D. Rose, Late Bedana, Green and Rose Scented has the high
values. The cultivars Purbi, China, Swarna Roopa and Dehradun has thick peel. Widely
spread protuberances was noticed in cultivars Swarna Roopa, Dehradun and Bedana.
Bedana, Late Bed;ma and Swarna Roopa had smaller seeds. The cul/ivars Bombaiya-1,
Bombaiya-11, Late Bedana, CHES-II, China and Purbi had slender seeds while Deshi,
Bombaiya-1 and Late Bedana has flat seeds.
