This is the VOA special english agriculture report.

White rice is the world's most popular form of rice, but it goes throught a milling process every moves many nutrients. As result, people eat a poor diet based on white rice may not get enough vitamin A.

Each year, an estimated 200,50000 to half a million children go blind from vitamin A deficiency. The World house organization says half of them die within a year of losing their sight. Vitamin A deficiency is a problem especially in Africa and south-east Asia. So scientists thought an answer. They combined white rice with plant compounds that the body can change into vitamin A. Rice contains B and other C. This plant colorings give the rice a golden color.

This sientists also thought of a plan to give a way this golden rice for free to poor farmers. But the rice is genetically engineered. They say it can't be made using traditional methods to breed plants. The scientists worked for ten years until 1990 to develop the technology to add genes to rice. Then took nine more years to get genes they wanted  into the seed. The first feel test took place in 2004 at L university in the United States.

Golden rice is currently being tested in the Phinippines. It is still not available for general used. C says rice with two added genes will be available in 2013. One gene comes from maize or corn and the other comes from the soil bacterium.

Mr. Patrick blames the delays on too many rules about genetically modify crops. Opponents say such crops may caused environmental damage by breeding with conventional plants. The opponents also questioned the safty of bil-tech foods. Mr. Patrick says golden rice has never been shown to unsafety for the environment or people.

Many agricultural organizations support the project. But they are also critics including researchers for the environmental group Green peace. Several years ago, they questioned whether the golden rice could do much for vitamin a deficiency. They said releasing genetically modify rice in Asia could permanently change traditional rice varieties and wild ancestors of rice.
