一九六○年以来,世界上栽培半矮杆小麦的范围已显著扩大。Dalrymple估计,在发展较少的国家里,半矮杆品种尚占其小麦生产的44％。而在发展较多的国家里,半矮杆品种所占的面积则相当大。目前看来,半矮杆品种可能占世界小麦播种总面积的50％。但追溯其中大多数品种的祖先,都源出于日本半矮品种“Daruma”和“Akokomug”。Daruma是“Norin10”的一个亲本,此品种在小麦绿色革命中起了关键性的作用。 Since 1960, the world has been significantly expanding the range of semi-dulled barley. Dalrymple estimates that semi-dwarf varieties still account for 44% of wheat production in less developed countries. In more developed countries, the area of ​​semi-dash varieties is quite large. At the moment, semi-dwarf varieties may account for 50% of the world’s total sown area of ​​wheat. But the ancestors that trace most of them are derived from the Japanese semi-dwarf varieties “Daruma” and “Akokomug.” Daruma is a parent of “Norin10,” a species that has played a key role in the wheat green revolution.
