The lack of suitable early selection parameters means that traditional rubber breeding for yield is time-consuming and inefficient. Laticifer is a tissue specific for natural rubber biosynthesis and storage in rubber tree. The number of the secondary laticifers in the trunk bark tissues is positively correlated with rubber yield in the matured rubber trees that are regularly tapped. In the present study, the rubber yield from 280 of 4–5 year-old virgin trees from 7 cross combinations was compared with the number of newly differentiated secondary laticifers caused by tapping. Results showed that the number of tapping-induced lines of secondary laticifers varied in different germplasm and was positively related to the rubber yield, indicating this could be used as a suitable parameter for early evaluation of yield potential of rubber trees.

Fig.1  Light micrographs of bark cross-sections, showing the tapping-induced secondary laticifers. The lines of lacticifers appear dark brown or black in these sections. The number of lines of induced secondary laticifers was>6 (a), 5–6 (b), 3–4 (c), and<3 (d). The secondary laticifers lines in the white, red, and orange squares were formed under natural conditions before tapping, in the first half year, and in the second half year after tapping, respectively. Ca, vascular cambia. Scale bars, 200 µm.
