当前蔗糖生产上迫切要求高产、高糖、宿根性好、适应性广、抗逆性强(主要是抗病虫、抗旱、抗寒)的甘蔗优良品种。而选育这种较全面的品种至今尚未取得更大的突破,其主要原因之一是甘蔗原始资源不够丰富,杂交亲本范围不广、血缘较近;现已育成的品种几乎全部是甘蔗属的中国种、热带种、爪哇割手密反复交配的后代。经过二十几年来定植二百多万株实生苗的选育,其基因型有限,要获得新的成就必须有更多的遗传类型作基础。为此,经过多次在全国甘蔗科研协作会议上的商讨,认为必须分充利用我国丰富的甘蔗原始资源,采取专业和群众相结合的方法,广泛收集各不同纬度、海拔
The current sucrose production urgently requires high yield, high sugar, good rooting, wide adaptability, strong resistance (mainly resistant to pest, drought, cold) of sugar cane varieties. However, one of the main reasons for choosing this more comprehensive breed has not yet achieved a greater breakthrough. One of the main reasons for this is that the original resources of sugarcane are not rich enough, the range of crossbred parents is not extensive and their blood relatives are relatively close. Almost all breeds that have been bred are Saccharum Chinese species, tropical species, Java cut the secret of repeated mating offspring. After more than two decades of colonization of over 2 million seedlings, their genotypes are limited, and more genetic types must be used as a basis for new achievements. To this end, after many discussions in the national sugarcane scientific research collaboration, that must be fully utilized our original rich resources of sugarcane, to take a combination of professional and mass methods, a wide range of different latitudes, elevation
