Xuan Van pomelo is a sweet early-ripening pomelo variety of Tuyen Quang province, Xuan Van pomelo originated from Soi Ha village, Xuan Van commune, Yen Son district. In order to have scientific basis and identify appropriate technical measures to improve the quality of Xuan Van pomelo fruit in a sustainable manner, research on agro-biotech characteristics is very necessary. Research results in 2015-2016 on agro-biological characteristics of Xuan Van pomelo variety show that the tree height is from 611.8 to 677.5 cm; the canopy and root diameters are from 704.5 to 715.5 cm and 16.99 to 17.05 cm respectively; Flowers often bloom from the 10th to the 21st of February and cease to bloom from the 5th to 13th of March, the time from blossoming to off-stage lasts from 22 to 27 days. The fruit weight is from 0,906 to 0,912 kilograms, the average fruit number ranges from 96,5 to 142,3 fruits/tree, with an average yield of 88,0-128.9kg/tree. Number of seeds from 122.9 to 124.6 seeds per fruit, average number of pods from 13.4 to 13.43 pods per pod, Brix level is from 10.93 -10.97%, 52.4 - 53.2% of which can be edible.
