USM Rb 1 Rubber (USM rubber clone): Characteristics
USM Rb 1 is a registered rubber variety, also sold or known as USM rubber clone or NSIC Rb 03. It was registered with the National Seed Industry Council in 1999 as NSIC 1999 Rb 03. It comes from University of Southern Mindanao.
The average and top yields in tonnes per hectare come from the trials each variety went through to be registered with the NSIC, and from what the seed companies say about their own seed.
What farmers harvest today can be different. Newer harvest records, the season, the place, the soil, the water and the care all move these numbers over time.
So use them to compare varieties, not as a promise for your field. Ask your seller or your agriculturist how the variety did on farms near you in the last few seasons.

Where and when to plant USM Rb 1 rubber
Rubber clones differ in latex yield and in how they take tapping and wind. Plant budded clones from an accredited nursery. A registered tree variety is a selection from one proven mother tree, and only grafted, budded or marcotted plants carry its traits. A seedling grown from its seed can turn out quite different. So buy from a nursery accredited by the Bureau of Plant Industry, and ask which mother tree the scions came from. Before planting, get the field ready with our guide: Land preparation in the Philippines.
Before you buy planting material
- Buy grafted or budded plants from an accredited nursery, with the variety name on the tag.
- Ask your municipal agriculturist or nearby farmers how it did in your area last season.
- Plant a few trees first if the variety is new to your area, before you fill the whole farm.
- Write down the planting day, inputs and harvest, so you can compare varieties on your own ground. anee.io keeps these records for you.
