The present study shows the results of the joint application of the Cluster Analysis (CA) and Principal Component Analysis (PCA) in 20 maize inbred lines of different maturity groups. Some of them are components of maize hybrids, which are widely used in the agricultural practice in Bulgaria. Others are in the government ecological set and a third group are included in breeding schemes and are tested in the experimental field of MRI – Knezha.
The results of the analysis of the characters with the most significance in this grouping fully characterized inbred lines, which increases the efficiency of the selection process when working with them.
