The effect of fruit loading on yield and quality of pummelo (Citrus grandis (L.) Osbeck 'Thong Dee') was studied using varied numbers of fruit on the tree. Twelve 13-year-old pummelo trees planted at the farmer's orchard in Chaiyaphum province, northeast of Thailand were selected. The experiment design was a randomized completely block design (RCBD) with 3 fruit thinning systems (4 replications), 0, 10 and 20% fruit thinning from whole fruit number in each tree. The results showed that 20% fruit thinning had the highest grade A fruit size (40.53%). In addition, the fruit drop had the lowest percentage in this treatment. However, fruit thinning had affected the fruit length/circumference and reduced the ascorbic acid content in the juice.
