The presence of Intraxylary Phloem (IP) tissue were quantified and variability assessed in a set of Hevea brasiliensis clones. It is expected that the presence of an additional phloem tissue will promote better translocation along with the external phloem. The present work discusses genetic variability of IP in relation to growth and girth increment rate of newly evolved clones in a clonal nursery. Four clones (704, 690, 712, 688) were identified with robust girth, high girth increment rate and high prevalence of IP, in comparison with similar parameters present in the check clone i.e., RRII 429, adapted and recommended for abiotic stress prone non-traditional areas. Results indicated that variability in the number of IP could be an intrinsic anatomical trait useful for screening and shortlisting of clones for non-traditional areas.
