It is still not available for general use. 目前還未廣泛使用/量產(chǎn)。
Co-inventor Ingo Potrykus says rice with 2 added genes will be available in 2013. One genecomes from maize, or corn, and the other froma soil bacterium.
Mr.Potrykus is retired from the Swiss FederalInstitute of Technology. He blames the delays on toomany rules about genetically modified crops.

Opponents say such crops may cause environmental damage by breeding with conventionalplants. Opponents also question the safety of biotechfoods.

Mr.Potrykus says Golden Rice has never been shown to be unsafe for the environmentor people. Many agricultural organizations support the project.
Butthere are also critics, including researchers for the environmental groupGreenpeace. Several months ago they questioned whether Golden Rice could domuch for vitamin A deficiency. They said releasing genetically modified rice inAsia could permanently change traditionalrice varieties and wild ancestors of rice.

2004年美國(guó)的路易斯安那州立大學(xué)舉行的首次實(shí)地試驗(yàn)。現(xiàn)在菲律賓已經(jīng)開(kāi)始測(cè)驗(yàn)黃金米。但黃金米仍然沒(méi)有得到大范圍推廣使用。
發(fā)明人之一，印戈·伯特利庫(kù)斯說(shuō)：“添加了兩個(gè)新基因的稻米將于2013年提供使用。”其中一個(gè)基因提取自玉米，另一個(gè)提取自一種土壤細(xì)菌。
退休前，伯特利庫(kù)斯是瑞士聯(lián)邦理工學(xué)院的一員。他指責(zé)過(guò)多的規(guī)定限制了轉(zhuǎn)基因農(nóng)作物的發(fā)展。
反對(duì)者說(shuō)轉(zhuǎn)基因農(nóng)作物和傳統(tǒng)植物的雜交可能會(huì)破壞環(huán)境。反對(duì)者還質(zhì)疑基因食物食用的安全性。
伯特利庫(kù)斯說(shuō)還從未出現(xiàn)過(guò)黃金米對(duì)環(huán)境或是人類(lèi)造成危害的現(xiàn)象。許多農(nóng)業(yè)組織支持這項(xiàng)工程。
也不乏有像包括環(huán)境組織“綠色和平”的研究人員在內(nèi)的批評(píng)者的聲音。幾個(gè)月前，他們質(zhì)疑黃金米是否能解決維他命A的缺乏。他們說(shuō)，在亞洲投入轉(zhuǎn)基因稻米可能會(huì)永久性改變傳統(tǒng)的稻米品種和野生的原種稻米。
