摘要
对196份甜高粱材料进行了糖锤度测定及综合评价,结果表明,糖锤度≥21%的材料49份,其中有4份材料糖锤度达到23%以上,糖锤度在16%~20%之间的材料113份,糖锤度≤15%的材料34份,供试材料糖锤度平均18.25%。对这些材料具有适应性广,籽粒产量高、有较强抗旱性和耐瘠薄性的特点,其中4份高糖锤度材料可以根据育种目标和生产需求进行性状改良,筛选和培育综合性状优良的材料,有直接应用于生产的可能。
Abstract: Brix sugar evaluation in 196 copies of sweet sorghum were studied. The resuhs showed that 49 copies had brix sugar ≥ 21%, of which four materials' brix sugar were more than 23%. 113 copies had 16%-20% brix sugar 34 copies had brix sugar ≤ 15%. On average, the all tested materials were 18.25% brix sugar. These materials had the charaeter of wide adaptability, high grain yield, and strong resistance to drought and barren. According to breeding goals and production requirements, we can improve traits, screen and train excellent comprehensive properties materials with 4 copies of high brix sugar. There also may be directly applied to production.
