摘要
利用灰色关联度分析的方法对15个高赖氨酸玉米双列杂交组合进行收获时籽粒含水量与穗部及籽粒性状的关联分析。结果表明,粒长、轴粗、穗粗、穗长与收获时籽粒含水量的关联度较大;粒重、容重次之;粒厚、粒宽最小。因此,选育收获时籽粒含水量低的高赖氨酸玉米,应选择粒较短、轴较细的类型,同时应注意选择长穗。
The grey related degree analysis were employed to invstigate the relationship
between grain moisture contained in mature time and some characters of ear and grain in
which 15 single crosses of QPM (Quality Protain Maize)inbreeding lines were involved.The
results indicate that the grey related degree of grain length, axis thickness of ear ,ear diameter
and ear length was in the first place; the grain weight and grain unit weight took the second
place; the grain thickness and grain width was least. therefore ,we ought to emphasize the grain
length and ear axis thickness in order to breed the QPM with lower moisure contained in mature
time. Meanwhile, we should select the maize which have long ear and big unit weight to avoid
reducing the yield.
