USM recommends high-yielding rubber clones

One of the country’s centers for collection and propagating of rubber clones, the University of Southern Mindanao (USM) in Kabacan, North Cotabato, recently released a list of recommended clone of rubber.

The list comprises of the following clones:RRIM 600 (Rb 99-01), RRIM 712, RRIM 901, PB 217(Rb99-02), PB 235 (Rb99-04), PB 260, USM 1 (Rb 99-03), PB 330, and PB311. Among the new clones, USM1 (Rb 99-03) has the highest dry rubber yield per year (2.5 tons/ha). PB 330 is also one of the highest yielding lines, recording an average annual yield of 2.38 tons/ha, closely followed by PB 260, producing 2.37 tons/ha per year.

Finishing Oil for Furniture

Finishing Oil for Furniture

From Rubber Tree


Rubber tree seeds produce oil. Researchers from FPRDI Los Baños found that furniture

applied with finishing oil from rubber tree seeds are more resistant to alcohol stain or anything

hot placed on top of furniture compared to ordinary finishing oil.


The proportion which may be applied with paint brush is as follows:

75% oil from rubber tree seed

25% paint thinner
