Abstract: This study was conducted during the years 2002-2003 at the Research Farm of NWFP Agricultural University, Peshawar (Pakistan) to compare selected maize populations for fodder parameters. Two maize populations, one developed through recurrent selection (DRS) and the other through mass selection (DMS), each comprising of 125 S1 families were tested in modified Randomized Complete Block Design (RCBD) with two replications. Six fodder related traits viz., plant height, internode length, stem girth, flag leaf area, dry matter content and fresh fodder yield were determined. Mean squares from the analysis of variance among S1 families for both maize populations indicated highly significant (p≤0.01) differences for all the parameters. Data ranged from 58.7-201.9 and 60.8-184.1 cm for plant height, 6.6-16.3 to 13.0-18.5 cm for internode length, 0.7-2.0 to 0.7-1.6 cm for stem girth, 9.7-177.2 to 9.0-120.0 for flag leaf area, 124.0-680.0 to 182.0-652.0 g kg-1 for dry matter content and 600.0-6720.0 to 360.0-5040.0 kg ha-1 for fresh fodder yield in DRS and DMS population, respectively. The mean values were 124.5 and 134.5 cm for plant height, 11.9 and 12.6 cm for internode length, 1.0 and 1.1 cm for stem girth, 52.1 and 43.8 cm2 for flag leaf area, 354.2 and 392.8 g kg-1 for dry matter content and 2167.9 and 2166.2 kg ha-1 for fresh fodder yield in DRS and DMS population, respectively. Coefficient of variation was comparatively smaller (less than 10%) for plant height, internode length and stem girth in the DRS population and plant height, internode length, stem girth and dry matter content in the DMS population. The wider range among S1 families of both populations depicts the existence of sufficient variation for these traits which can, therefore be exploited in maize breeding programs aimed at improving fodder characteristics.
