\textbf{Abstract}
\begin{abstract}
\normalsize{
Eleven genotypes of sudangrass viz. 337, 8614, HOK, SG-58, TV-3368, 958, 39501, \mbox{Succro}, 4158, Low HCN and 9580 were evaluated for genetic variability based on green forage yield, forage nutritional quality and their components in the sub"=tropical environment of Faisalabad in the central Punjab, Pakistan. The experiment was laid out as a randomised complete block design with three replications. In each replication \mbox{2\,m} long single rows of each entry were raised keeping between and within row distances of \mbox{60\,cm} and \mbox{15\,cm}, respectively. Data were recorded on five forage yield related and five forage quality related traits. Highly significant differences were observed for all the forage yield and quality parameters indicating the presence of sufficient genetic variability among the genotypes.  Genetic variability for plant height, no. of tillers per plant, no. of leaves per plant, leaf area and green forage yield per metre row ranged from 125.83 -- \mbox{205.93\,cm}, 4.83 -- 8.67, 6.67 -- 8.70, 190.66 -- 270.87 cm$^{2}$ and 3.67 -- \mbox{4.90\,kg}, respectively. Whereas, crude protein, ether extract, crude fibre, ash and nitrogen free extract ranged between 4.08 -- \mbox{5.75\,\%}, 1.35 -- \mbox{1.52\,\%}, 27.23 -- \mbox{28.40\,\%}, 6.78 -- \mbox{8.55\,\%} and 56.99 -- \mbox{59.75\,\%}, respectively. The genetic variability exhibited among the genotypes could be exploited in breeding programmes aimed at the improvement of high yielding genotypes with better nutritional quality. The performance of genotypes 337, HOK, 4158 and TV-3368 was appreciable; therefore, their use in the future breeding programmes is suggested.}
