茎秆高糖的能源玉米新品种选育研究

Selection of New Maize Combination with High Content Sugar Material

利用茎秆含糖量高的玉米自交系进行了能源玉米新品种的选育研究。结果表明:①津259、津1009、津1112、津2122、津单2号5个品种的茎秆产量、茎秆含糖量、子粒产量综合表现较好,可作为生产燃料乙醇的材料进一步试验;②玉米茎秆含糖量性状可以达到或超过甜高梁水平;③玉米各节间的含糖量变化比甜高粱相对稳定。

The selection and research of new maize combination based on high sugar content inbred line was studied. The results showed that the stems yield, sugar content and seeds yield of Jin259, Jinl009, Jinl 112, Jin2122 and Jindan2 were all excellent, so they could be regarded as alcohol raw material for further study. The sugar content of stem for them were up to grain sorghum or beyond it, the variance of its section was relative stable.
