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.
World demands for rubber is big, but hardly met. In our modern times, almost everything has some use for rubber. But no tall places in the world can grow the rubber tree, so it is in our hands to develop and enhance this industry.
Rubber needs a warm and humid climate (about 30-35’C) and uniform rainfall throughout the
year. It doesn’t like torrents of rain or long dry spells.
The soil good for rubber is the lowland soil that does not lodge water. It doesn’t grow in
