高粱核质杂种子粒品质杂交优势遗传效应研究

Genetic Studies on Grain QuaHty Heterosis of Sorghum Nucleo-Cytoplasmic Hybrids

研究结果表明,高粱核质杂种子粒蛋白质、赖氨酸、单宁含量具有杂交优势和超亲优势。遗传表现有核基因型,胞质基因型,核质互作型,各占一定比例。有些核质杂种的产量和蛋白质、赖氨酸含量都超双亲中最高值,单宁含量呈现比双亲显著降低的综合遗传效应。

The present paper reports some grain quality cheracteristics of sorghum nucleo-cytoplasmic hybrids. Results showed that the grain content of protein, ly-sine and tannin have averoge heterosis and heterobeltiosis.
