为选育生物量高的能源高粱(Sorghum bicolor L.Moench),本研究对不同类型的15个高粱品种和4个不育系,采用NCⅡ遗传交配设计,获得60个杂交组合,对地上部生物量等11个性状进行了配合力和杂交优势分析。结果表明:地上部生物量等10个性状的遗传是由加性和非加性基因共同控制,倒伏率主要受加性基因控制。父本NW-21、绿能3号和母本A3晋粱5A地上部生物量的一般配合力效应值极显著高于对照,是适宜组配高生物产量能源高粱杂交种的父、母本材料。A3三尺三A×绿能3号和A3三尺三A×Saccaline是地上部生物量特殊配合力效应值较高的组合。杂交高粱中在地上部生物量上存在超标优势。
In order to breed sorghum bicolor L.Moench with high biomass, 15 different sorghum varieties and 4 male sterile lines were selected. Sixty hybrid combinations were obtained by NCⅡ genetic mating design. The amount of 11 traits such as combining ability and heterosis analysis. The results showed that the inheritance of 10 traits such as aboveground biomass was controlled by additive and non-additive genes, and the lodging rate was mainly controlled by additive genes. The results showed that the general combining ability (GCA) of aboveground biomass of parent NW-21, green energy 3 and female A3 A3 Jin Liang 5A was significantly higher than that of the control, which was suitable for the combination of parents and maternal materials of high biomass yield sorghum hybrids . A3 three feet three A × green energy 3 and A3 three feet three A × Saccaline is a combination of aboveground biomass special combining ability effect value. There were over-standard advantages in the above-ground biomass of hybrid sorghum.
