«The discovery that regulation of the Shell gene will enable breeders to boost
palm oil yields by nearly one - third is excellent news for the rainforest and its champions worldwide,» says Datuk Dr. Choo Yuen May, the Director General of the Malaysian Palm Oil Board (MPOB), an agency of the Malaysian federal government.

oil palm: how the thickness of its shell correlates to fruit size and
oil yield,» explains Dr. Rajinder Singh of the MPOB, first author of the Nature paper describing the Shell gene.
Currently, it can take six years to identify whether an
oil palm plantlet is a high -
yielding palm.
«Accurate genotyping for enhanced
oil yields will optimize and help stabilize the acreage devoted to
oil palm plantations, providing an opportunity for the conservation of rainforest reserves,» Martienssen explains.

NB: Done right,
palm is the highest
yielding vegetable
oil on the planet, producing five to 10 times more
oil per acre compared to other commodity oils (like soybean or canola).
But it is most useful in the kitchen,
yielding coconut
oil, coconut milk,
palm nectar,
palm wine, coconut meat («copra»), and coconut juice.

yields of
palm oil plants in converted landscapes, such as Sumatra, are causing significant nitrous oxide emissions.
As the world's highest
yielding oilseed, the crop generates substantially more vegetable
oil per acre than soy, canola (rapeseed), or corn, meaning that
palm oil can help meet future demand for vegetable
oil with less land, a point
palm growers are quick to mention in any discussion over the environmental impacts of
palm oil.
Although production from
oil palms is limited to tropical and subtropical regions, the crop
yields much more biodiesel per acre than do temperate - zone oilseeds such as soybeans and rapeseed.
Other research has shown that several common biofuel feedstocks — including corn and rapeseed which have considerably lower
yields than
oil palm — also have high emissions from direct and indirect land use.
By virtue of its high
yield,
palm oil is a cheaper substitute than other vegetable oils.
Faced with a seemingly insatiable demand for automotive fuel, farmers will want to clear more and more of the remaining tropical forests to produce sugarcane,
