N2  - Twenty two hybrid clones of rubber (Hevea brasiliensis Muell. Arg) evolved at the Rubber Research Institute of India were evaluated for growth and dry rubber yield in a clonal nursery and in the main field in small-scale trials. Clones with good yield and stable performance in the nursery were selected by a rank-sum method. Juvenile-mature correlations were worked out in an attempt to study the prospects of reducing the time span of clonal selection. Significant positive correlation between juvenile yield in the clonal nursery and initial yield at maturity suggested scope for preliminary evaluation of clones in a nursery
