摘要:

为了筛选优异黍子育种材料,为本地黍子育种工作提供参考依据,本试验对24份黍子品系材料的农艺性状进行主成分和聚类分析,并做出综合评价。结果表明,提取的4个主成分累积方差贡献率为84.9%,反映了原指标大部分信息。而在这24份材料中,‘201-8’和‘06-D69’的综合评分最高。通过聚类分析,将所有材料划分为4个类群,第一、二类评分结果和产量表现较好,均分为41.78和38.48,平均产量为251.1 kg/hm2和210.6 kg/hm2,这些材料可以在之后的黍子育种工作中优先考虑;第三类在评分产量方面表现不佳,分别为37.69 kg/hm2和185.1 kg/hm2,但其株高、穗长、基茎粗等指标表现较好,可在培育抗倒伏品种等育种工作中考虑;第四类材料评分及产量均为最差,分别为33 kg/hm2和169 kg/hm2,其他指标也不理想,不建议进行育种培育工作。

Abstract:

To screen excellent breeding materials for broomcorn millet and provide reference for its local breeding, the agronomic traits of 24 broomcorn millet materials were analyzed by principal component analysis and cluster analysis, and a comprehensive evaluation was conducted in this experiment. The results showed that the cumulative variance contribution rate of the four extracted principal components was 84.9%, which reflected most of the information of the original indexes. ‘201-8’ and ‘06-D69’ had the highest comprehensive scores among the 24 materials. The test materials were grouped into four categories, the score and yield of the first and second categories were better, the average score was 41.78 and 38.48, respectively, and the average yield was 251.1 kg/hm2 and 210.6 kg/hm2, respectively. These materials can be given priority in variety breeding. The score and yield of the third category was poor, 37.69 and 185.1 kg/hm2, respectively, but the plant height, spike length, basal stem diameter and other indicators were better, which could be considered in breeding lodging-resistant varieties. The materials of the fourth category scored the least and had the lowest yield, 33 and 169 kg/hm2, respectively, and other indexes were not ideal too. Therefore, the materials of the fourth category are not recommended.
