  英国剑桥国家农业园艺研究所表示,他们将一种原始小麦品种与一个现代麦种杂交,开发出了这种新型的高产量小麦品种。新品种小麦的整个杂交过程未使用转基因技术。

  在早期实验种植过程中,这种超级小麦比现代小麦个头更大、更强壮、产量也更多。

  从测试到最终在田间种植还需至少5年的时间。

  一些农户则认为,由于全球粮食供给面临前所未有挑战,因此政府对粮食新品种认证周期应缩短,以便类似高产新品种可尽早投入实际生产。

British scientists say they have developed a new type ofwheat which could increase productivity by 30%.

TheCambridge-based National Institute of Agricultural Botany has combinedan ancient ancestor of wheat with a modern variety to produce a new strain.

In earlytrials, the resulting crop seemed bigger and stronger than the current modernwheat varieties.

It will take atleast five years of tests and regulatory approval before it is harvested byfarmers.

Some farmers,however, are urging new initiatives between the food industry, scientists andgovernment.

They believethe regulatory process needs to be speeded up to ensure that the global foodsecurity demands of the next few decades can be met, says the BBC’s Tom Heap.

One in five ofall the calories consumed round the world come from wheat.

But despitesteady improvement in the late 20th century, the last 15 years have seen littlegrowth in the average wheat harvest from each acre in Britain.

Just lastmonth, cereal maker Weetabix announced thatit would have to scale back production of some of its products due to a poorwheat harvest in the UK.
