利用冬季在海南岛对当年新选配的杂交组合即作鉴定,先行筛选糖锤度表现突出的组合,翌年提前进入品种比较试验方法的尝试,获得了圆满的结果。比较两地环境条件和试验结果,从海南到北京含糖量性状表现出了有相对稳定或增加的趋势,其他性状除生育期的变化比较大、秆重提高较多外,株高、穗长略有增加,粒重则无明显差别,该结果可为甜高粱育种工作提供有益的参考。
Using the combination of new hybrids of the year in Hainan Island in winter, it was identified that the combination of the first selection of sugar brix was outstanding and the trial of variety comparison test was advanced in the following year and the successful result was obtained. Comparing the environmental conditions and experimental results of the two places, the sugar content traits from Hainan to Beijing showed a relatively stable or increasing trend. The other traits except the growth period changed a lot and the stalk weight increased more. The plant height, spike length Slightly increased, no significant difference in grain weight, the results can provide a useful reference for the work of sweet sorghum breeding.
