高粱屬大約包含30,部分品種為糧食作物,大部分品種主要用於牧草,廣泛分布在全球各地,原產於熱帶亞熱帶地區,屬於禾本科中的蜀黍族

栽培和利用

高粱屬部分品種用做食品飼料、釀和制,(參見高粱),也可以用做生物燃料,但大部分品種是作為牧草,高粱屬幾乎所有品種都是耐旱作物,在熱帶草原是非常重要的組成部分,在非洲南亞也是最重要的糧食作物,在全世界的糧食生產中占第五位。[1]
其中一種品種假高梁(Sorghum halepense)被美國農業部認定為美國的入侵物種[2]
有的品種秸桿外皮可以編製席子,有的品種糖高粱秸桿含糖,可以製作糖漿,印度實驗將其糖分轉化為酒精燃料,[3]美國正在尋找能將其秸桿和葉子轉化為酒精燃料的最佳品種[4]
中國,高粱是最好的釀造白酒的原料。


Critical advancement in sorghum research helping to feed millions

About sorgum Page_hands_webGlobal consortium of scientists achieve research breakthrough to make sorghum crop more nutritious; will contribute to food and nutrition security

An important step toward introducing pro-vitamin A (beta carotene) into sorghum, a staple food in Africa which is naturally deficient in key nutrients, has been taken. According to a DuPont announcement today, not only has the level of pro-vitamin A been improved to levels that result in delivery of 100 percent of the daily vitamin A requirement in children, but the stability of pro-vitamin A during storage also has been dramatically improved. These research breakthroughs will help improve nutrition for the nearly 300 million people in Africa who depend on sorghum, but who do not have access to another staple that provides the essential nutrients that sorghum lacks.

Schickler. “The achievement of enhancing both the quantity and stability of pro-vitamin A in sorghum marks a critical advancement in ensuring local farmers cannot only grow more food, but more nutritious food.”
The ability to achieve 100 percent of the recommended daily allowance of vitamin A in children from sorghum has never been achieved before.
