The planting materials approved by the Rubber Board are classified in to three categories I, II and III.

Category I

Approved for large scale planting. However, it is strongly recommended that these may be used to cover only 50% of the total area of any estate or small holding.

Category II

Clones, which have shown their good performance in India over long term or medium term periods. It is recommended that three or more of these clones be used to plant up to 50 per cent of the total area of any estate or small holding.

Category III planting materials are divided into

Those, which have held out promise of good performance in small-scale trials, and over short term in some large scale trials in India or abroad. Hence these are approved only for experimental planting Old selections having promising localized performance or having desirable secondary attributes. In regions where these clones are showing very good performance, no restriction in planting is insisted. Modern clones with moderate scale performance are included in division Other experimental clones of promising yield and/or desirable secondary characters with limited data are included in division Selections from any of these are recommended for very small scale planting not exceeding 15 per cent of the total area Category I	Clones RRII 105 and PB 260 (RRIM 600 and GT 1 in non traditional areas) Category II	Clones RRIM 600, GT 1, RRII 5, RRII 203, PB 28/59, PB 217, RRII 414, RRII 417, RRII 422 and RRII 430
