Abstract

The results of investigation on early evaluation of compatibility between commercial citrus varieties, and Kaffir lime (Citrus hystrix) and Carrizo citrange (C. sinensis Osb. x P. trifoliata L. Raf.) rootstocks, at Mekong Delta Vietnam, during four successive years from 2010 to 2013, reported that out of the tested combinations of the recent commercial citrus varieties, included Da xanh pumelo (C. grandis Osbeck), seedless Mat orange (C. sinensis L. Osbeck), Sanh orange (C. nobilis Lour.) and Duong mandarin  (C. reticulata), budded on Kaffir lime and Carrizo citrange, in the 3rd and 4th  year after planting under the trial fields at Mekong Delta Vietnam, the trees of Sanh orange (C. nobilis Lour.) budded on Kaffir lime (Citrus hystrix) were supperior with precocity, producing high number of fruits (16.67 fruits per tree ), and very good fruit quality of larger fruit size (334.6 g and 11.16 cm, fruit weight and diameter, respectively), higher total soluble solids (12.5 brix), better orange-yellow juice color development, and excellent flavor and aroma of juice, as compared to the typical characteristics; meanwhile these were followed by trees of seedless Mat orange budded on Kaffir lime, which produced the highest number of fruits (47.33 fruits per tree), with little inferior quality of seedy fruit (1-3 seeds per fruit), lower total soluble solids (7.33%), and no good flavor and aroma, as somewhat differed from the typical fruit traits.
