Golden Rice Could Supply Up to 50% of the Average Daily Requirement of Vitamin A

A team of scientists from the International Rice Research Institute
(IRRI), Philippine Rice Research Institute (PhilRice), and Bangladesh
Rice Research Institute (BRRI) reported that Golden Rice (GR2E)
introgression lines showed significant amounts of carotenoids in the
milled grains.

The researchers used marker-assisted backcross breeding to transfer the
GR2E trait into three local rice varieties. The resulting introgression
lines were tested on confined fields to evaluated their agronomic
performance and expression of beta carotene, vitamin-A precursor. The
field tests showed that the introgression lines have similar
characteristics as the recurrent parents and no differences were
observed in pest and disease reaction.

The best performing lines were found to supply 30% to 50% of vitamin A
daily average dietary requirement.
