为了鉴定高粱属品种、系统特性时的性状选择,以及对所选择的性状进行分类,对高粱属的14个种76个系统的46个性状进行了调查研究。根据性状间相关性及主成分作用效应等,选择了光泽性等21个性状作为系统分类的主要性状。在以此21个性状所做的主成分分析中,根据第一主成分的评定值首先进行原生单源种的分类,又根据第二主成分进行种与系统群内形态及生态的分类,再根据第三主成分在种、系统群内依据籽粒品质进行分类。在栽培种中分成2个群,在栽培种与草高粱野生种之间的种与系统中分成2个群,在草高粱野生种中分成2个群,计分成6个群。轮生花序高粱与最早的栽培种双色高粱亲缘关系较远。对野生轮生花序高粱向栽培双色高粱的进化过程进行了研究。
In order to identify the sorghum varieties, the traits of the traits in the system traits, and the traits of the selected traits, 46 traits of 14 76 species of Sorghum were investigated. According to the correlation between the traits and the effect of the principal components, 21 traits such as glossiness were selected as the main traits of the systematic classification. According to the principal component analysis made by these 21 traits, the classification of primary single-source species is carried out according to the evaluation value of the first principal component, and the classification of the species and the system’s internal morphology and ecology according to the second principal component is carried out. Then, According to the third principal component in the species, the system group classification based on grain quality. Divided into two groups in cultivated species, divided into two groups in the species and system between the cultivated species and the wild species of Sorghum bicolor, and divided into two groups in the wild species of grass sorghum, which were divided into six groups. The flower inflorescence sorghum is distantly related to the earliest cultivated species of two color sorghum. The evolution of wild round inflorescence sorghum to two-color sorghum was studied.
