【摘要】 糯高粱杂种１代籽粒粗蛋白、单宁、总淀粉、直链淀粉和支链淀粉含量的平均优势、超亲优势和相对优势均为负值。总淀粉、直链淀粉和支链淀粉含量的对照优势为正值。粗蛋白、总淀粉和支链淀粉含量呈负向优势。单宁和直链淀粉含量呈负向部分显性，表明利用糯高粱Ｆ１显性效应有一定困难，育种时应注意高值亲本的选择更多还原

【Abstract】 The crude protein, tannin, total starch, amylase and amylopectin of glutionous sorghum grain were analyzed. The results indicated that the average, the superhigh and the relative heterosis of crude protein, tannin, total starch, amylase and amylopectin content were all negative while the contrast heterosis of total starch, amylase and amylopectin were positive. This shows that there are some difficulties in the application of the dominant effects of the glutinous sorghum and so the parents of glutinous sorghum grain with those high content must be selected as the breeder.更多还原
