对黑龙江省 10 0份高粱基础材料进行了总淀粉、直链淀粉和支链淀粉含量的测定。其中总淀粉含量高于 70 %的有 4 1份 ,占总数的 4 1% ;支链淀粉含量高于 80 %的有 16份 ,占总数的 16 %。在高粱育种中 ,可利用这些材料进行高淀粉杂交种的组配 The contents of total starch, amylose and amylopectin in 100 basic sorghum materials in Heilongjiang Province were determined. Among them, 41 were total starch content higher than 70%, accounting for 41% of the total; 16 were more than 80% amylopectin content, accounting for 16% of the total. In sorghum breeding, these materials can be used for the formulation of high-starch hybrids
