Specimens screened and collected during October to November 2009 from local sites in Borklua district, Nan Province. Seventeen clones are coded as Nan-1 to Nan-17. Nan-14 produces fruits of largest size 2.67 cm. in diameter and also of high quality. Extracts percentage is highest around 62.11+-0.87 and contains largest content of vitamin C at 470.13 mg/100 gm fruit flesh. Clones which give lesser extracts percentage are Nan-5, 13, 15, 11 at 55.54+-0.92, 54.63+-2.00, 53.75+-1.82, and 52.97+-2.17 percent, respectively. Clones produce least vitamin C are Nan-10, Nan-9, Nan-15 and Nan-5 at 450.49, 418.30, 342.69 and 340.23 mg/100 gm fruit flesh, respectively. Other qualities such as fiber, sugar content, acids and pH are also differ. Nan-13 has the most fiber of 3.05 percent and Nan-6 the least at 1.95 percent. Nan-3 gives highest sugar content of 18.75 deg Brix while Nan-2 the lowest at 10 deg Brix. Acids are found at 4.45 percent in Nan-3 and the lowest of 2.67 percent in Nan-15. pH is highest in Nan-13 at 3.11 and the least of 2.50 in Nan-14. Analysis of emblic leaves of all 17 clones (DNA fingerprint) by AFLP (Amplified Fragment Length Polymorphism) marker numbering 10 primers of which the outcome would be drawn into Phylogenetic tree. From similarity index, it shown that lines are almost identical is 0.7755 (77.55 percent) i.e. Nan-11 and Nan-14. Line that differs most from other is Nan-1: 0.6746 (67.46 percent).
