Abstract

The aim of this study, conducted during the years 2005 (Y1) and 2006 (Y2), was to investigate the variability and appearance of genotype reaction in maize inbred lines. In the investigation were included 10 maize inbred lines obtained from the University of Tirana- Albania, department of Agronomy. The experiment was based on a ranomized complete block design (RCBD) with three replications in the locality of Ferizaj. The variability and genotype reaction was analysed for quantitative parameters for plants as following: Ear height (EH); plant height (PH), ear leaf area (LA) and leaf area index (LAI). The experimental average values μ for investigated parameters were: EH was 60.46 cm, PH (169.88 cm), LA (446.2 cm2) and LAI (3.23 plant m-2) respectively. The inbred lines between them for EH at the first year (Y1) and the second year (Y2) had show the variability 52.59% and 43.16%, respectively. The highest value for EH was shown by inbred L4 (76.10 cm), which differs from the value μ for +25.86%. While the lowest value was recorded at the inbred L5 (44.30 cm) that difference was a reduction of– 26.72%. In the Y2 the same values were repeated but with minimal differences. The maize inbred L7 for the Y1 had a greater total plant height (196.5 cm), while for the Y2 was obtained 206.7cm. The minimal average value for PH were shown by the inbred L8 and L2, while the total variability between all inbred lines for PH were Y1 (32.61%) and Y2 (36.55%) respectively. Average values of the two years investigation for ear leaf area (LA) were obtained by inbred L7 (544.1cm2 plant-1), whereas lowest values were showed by maize inbred L10 (356.9cm2plant-1). Variability between inbred lines was 41.95 %. The highest value of LAI was obtained for inbred L7 on coefficient 3.9 plant m2 (Y1) and 4.0plant m-2(Y2) whereas the lowest LAI was realised on maize inbred L10 (2.5 plant m-2) at the Y1, while for the Y2 was obtained at maize inbred L8 (2.6 plant m-2).
