甜高粱育种思路探讨

Discussion on Breeding in Sweet Sorghum

甜高粱生物产量高,含糖量高,乙醇转化率高,抗逆性强,是能源作物,对其合理开发利用,对我国粮食安全、能源安全具有重大意义。我国甜高粱育种水平落后,现有品种不能适应生产发展的需要。创新育种思路,可从选育粮糖兼用型品种和自交不结实的品种方面进行甜高粱品种选育。

As an energy crop,sweet sorghum has high yield,high content of sugar,high inversion rate of alcohol and stronger capacity in stress resistance.Sweet sorghum would have an important role for the food and energy security in China in condition of reasonably exploitation and utilization.The level of sweet sorghum breeding was rather low in China,so the available breed varieties fail to adapt production development.The breeding mentality of selecting the sweet sorghum variety of grain-sugar dual-purpose model and self-infertile model were discussed.
