How many different rubber clones in one area ? Obviously, it is easier to develop a few clones. In some extreme cases, only one clone was developed over large areas. Clonal diversification reduces the levels of risks, and favors the stability of rubber material quality along time. We can never really predict the behavior of one clone on one site over more than 25 years. But there is another reason to promote clonal diversification. This allows the discovery of unexpectedly well-adapted clones to new situations and to further unpredictable changes. Thus clonal diversification paves the way to efficient innovation. A simple scheme may be to plant 10 clones with the following ratios : 20 %, 15 %, 15 %, 10 %, 10 %, 10 %, 5 %, 5 %, 5 %, 5 %. Concerning the last 5 %, this can be not only one clone but a number of different clones in block areas of 5-50 ha which can thus be observed on a large scale for performance and adaptation. Moreover, Large Scale Clonal Trials should be regularly set to study the behavior of new unknown selected clones.
