Scientists from a research institute in the Philippines have recently discovered a gene that can boost the production of one of the world’s most popular staple food—the rice.

The International Rice Research Institute (IRRI) is a non-profit institute that researches mainly on different rice varieties. It has long been searching for genes that can multiply rice production. Finally, the institute’s breeders were able to find a wonder rice gene that improves rice yield.

Breeders from the institute discovered that rice yield increases when the SPIKE gene is infused into the “indica” rice varieties, which are the most used types of rice. SPIKE gene is from an Indonesian rice variety called “japonica.”

According to the findings of the preliminary tests, infusing “indica” rice varieties with SPIKE gene results in 13 to 36 percent increase in rice production. Increasing rice yield means more rice will be produced even with limited land resources. IRRI also stressed, however, that this method is not a form of genetic modification.

Rice is not only a staple food in many countries; it is also the most important crop in the world, especially in Asian countries. Thus, IRRI’s discovery may be very beneficial in ensuring food security and making the price of rice more stable.

However, IRRI is not yet sure when the SPIKE-infused rice can be distributed to farmers as further research may still be needed.
