Adapted from C.C. Webster & Baulkwill, 1989.

There is no official international registration authority for Hevea cultivars, but cooperation between breeders and others in various countries has led to the general adoption of a system whereby a clone is designated by letters indicating its place of origin and a serial number assigned to it by workers at that place. Names of more than one word are abbreviated to the initial letters of each word in capitals without full-stop points between them, e.g. RRIM for Rubber Research Institute of Malaysia. Single word names are abbreviated by giving the initial capital letter only, by two letters if both are consonants, e.g. Ch for Chemara, or occasionally by three or more letters, e.g. Pil for Pilmoor. Some exceptions to these conventions are in use, either because they are long established, or to avoid confusion between similar names such as Tjiomas and Tjirandji. A space is left between the abbreviation of the name and the serial number. If the latter is prefixed or suffixed with a serial letter, this is run on with the number, e.g. Pil A44. Where a subdivision of a series is indicated by a number, this is shown by an oblique stroke, e.g. PB 5/63. The following list gives the names and abbreviations of the places of origin of the better known clone series.

Clonal seedling families

Most plantations of clonal seedlings are established with seed resulting from self or cross-pollination in isolated seed gardens which have been planted with clones of buddings selected for their ability to give high-yielding seedling families when crossed in all combinations. Seed collected from a mixture of clones in such a garden is designated by letters indicating the name of the garden, e.g. PBIG/GG 1 for Prang Besar Isolated Seed Garden, Gough Garden 1. Seed collected from budded trees of one clone in a polyclone planting is denoted by the abbreviation for that clone, e.g. PB 5/51 seed. Seed obtained from an isolated monoclone planting, i.e. resulting from selfing of, or crossing between, budded trees of one clone, is designated by the abbreviation appropriate to the clone, with the suffix M for monoclonal, e.g. PB 5/51 M seed. Such seed may be useful for raising rootstocks for budding.
