Abstract

The diversity of morphological and genetic characters of 20 maize inbred lines was studied. The experiment involving 20 inbred lines (15 dent and 5 flint lines) was established during years 2004–2006 in the experimental field in Kobierzyce. The experiment was carried out using randomized complete block design with tree replications. Each experiment unit consisted of two rows spaced 75 cm apart. The following characters were analyzed: plant height, ear height, ear length, ear diameter, number of grain rows, ear mass, grain weight/ear, number of grains/ear, plant tillering, smut infection, dry matter content and grain yield. On the basis of available information it might be concluded that the lines were of different origin. Statistical calculations were carried out on the average values of each plot. Variance analysis showed that characters of maize inbred lines in years were different significantly, except the ear length, number of grain rows, plant tillering, and smut infection. Inbred lines responded differently to changing weather conditions for most traits. The lines were stable in years just for the following characteristics: ear height, ear length, grain mass, number of grain rows, and plant tillering. Of all the studied lines, K233 exceeded the standard line (F2) in terms of ear length, ear diameter, number of grain rows, ear mass, grain weight/ear, number of grains/ear, dry matter content, and grain yield. However, this line shows a tendency to smut infection.
