Coorg mandarin is acclaimed for its exquisite taste, quality, distinct flavor and keeping quality . It is predominantly grown, as an intercrop in the coffee-based cropping system in Kodagu region of Karnataka is more than a century. The area of Coorg mandarin was drastically reduced during last two decades due to Phytophthora, Citrus Tristeza Virus (CTV) and Citrus Greening Disease (CGD). An extensive field survey was undertaken in different Coorg mandarin growing regions and twenty high yielding diseases – free superior clones were identified. These clones were planted for field evaluation in randomized block design (RBD) during September 2006 CHES, Chettalli.. The growth observations revealed that average plant height was maximum in Clone -8 (2.72 m) followed by Clone -7(2.55 m). The rootstock and union ratio was between 0.98 to 1.02 while rootstock scion ratio ranged between 0.87 and 0.91. This indicates that all there no incompatibility with rootstocks in all selected clones. The maximum rootstock girth (22.77 cm) and scion girth (20.02 cm) was recorded in clone -7. The tree volume ranged from 3.40 m3 in clone-19 to 5.17 m3 in clone -4. The clone 4, clone-13, clone-7, clone-10 were found vigorous while clone-19, clone-18, clone-6 were found least vigorous. The highest average yield was recorded in clone –8 ( 14.82 kg/plant) while lowest yield was recorded in clone 18 ( 8.5 kg/plant). The average fruit weight ranged from 96.78 g (C-14) to 130.84g (C-8). The seeds per fruit was lowest un clone –3 (11.1). TSS was the highest (9.54oB) in C-17 and Clone – 8 (9.13 oB) in Clone-3. The flesh percent was highest in clone -8 (75.18 %). The fruits of the clone- 1 recorded the highest ascorbic acid content of 38.3 mg per 100 ml of juice while clone 13 registered the minimum (25.69mg/100 ml).Clone –8 was find best among all clone in term of plant height and yield and fruit weight.
