Khasi Mandarin

It is the chief commercial variety of Assam and has many local names after the places of production. Three is generally medium to tall with an erect habit densely foliaged both thorny and thornless.

Fruits depressed globose to oblate orange yellow to bright orange surface smooth glossy base even or obtuse occasionally short necked slightly ribbed rind thin soft adherence very slight or none segments 8 10 rag little to medium pulp vesicles uniformly orange coloured coarse very melting flavour agreeable juice abundant orange coloured. Sweetness and acidity well blended. Seeds 9 25 (usually 10 15). The most important mandarin in India undoubtedly is the Santra (Citrus reticulata) which includes varieties such as Nagpur santra CoorgSantra and Khasi orange.

Scientists felt that species standing was justified in the cases of Rangpur lime Rough lemon sweet lime galgal KharnaKhatta Kichili gajanimma attani Indian wild orange and Khasipapeda but were doubtful of the justification of granting species rank to adajamir of Assam amilbed sadaphal and sat Kara. They opined it would be justified if adajamir of Assam is treated as botanical variety of gajanimma of South India C. pennivesiculata. varassamensis and sat Kara as botanical variety of C. macroptera C. macropetera var. annamensis.

In Assam Khasi orange is grown in valley lands of submountane areas where the soils are of alluvial types and on the hills where the soils are mostly lateritic. Major citrus growing belts of Assam are sandy loam or clayey loam soil with pH 4.5 to 6.0 and with high organic matter content.
