The plantlets derived from citrus somatic embryogenesis (SE) in vitro have been widely produced. However, their vegetative and generative growth in the field has not been evaluated. The aimed of this research was to evaluate the ability of vegetative and generative growth both of SE and Budwood Multiplication Block (BMB) derived citrus plants. The research was conducted in Tlekung Experimental Garden, Indonesian Citrus and Subtropical Fruit Research Institute, from September 2013 to December 2016. The citrus plants derived from (a) root-decapitated plantlets and (b) buds come from BMB that were grafted and budded, respectively on 8 months old JC rootstock. One-year old grafted and budded plants were planted at field using a dense spacing (1.5 m x 1.5 m). The plant growth observation was done at 18–42 months after field transplanting (MAT). The results showed that the SE derived citrus plants could grow, develop, and produce as well as the BMB one. The SE and BMB plant height, scion, and rootstock diameter were not significantly different. All treatment plants were flowering on 18 MAT, the number of flower, fruit, and fruit set percentages were not significantly as well as in the following year. The fruit total in the 2nd year (September 2014) and the end of the observation (September 2016) showed an increase of 215.7% and 176.1% on the both of SE and BMB derived plant, respectively. In the 4th year (2016), the number fruits/plant and total fruit weight/plant were better on SE derived plant than BMB one, however the fruit physical and quality properties produced (vitamin C, total acidity, and TSS) were relatively similar. The Kintamani tangerine citrus plants derived from plantlet that grafted on to JC rootstock could grow develop and produce well in the field.
