Abstract: The present investigation was carried out at Department of Millets, Centre for Plant Breeding and Genetics, Tamil Nadu Agricultural University, Coimbatore, Tamil Nadu, India to identify the best performing Sorghum Downy Mildew resistant progeny for agronomical traits. The objective of this study was to identify the better <em>per se</em> performance of the resistant progeny. Nine biometrical characters of six SDM resistant progenies <em>viz., </em>UMI 79/936-C1-7-7-7-40, UMI 79/936-C1-7-7-7-46, UMI 79/936-C1-7-7-7-48, UMI 79/936-C1-7-7-7-52, UMI 79/936-C1-7-7-7-80 and UMI 79/936-C1-7-7-7-92 were used for mean performance. Studies revealed that among the progenies, UMI 79/936-C1-7-7-7-S80 and UMI 79/936-C1-7-7-7-92 showed better <em>per se </em>performance<em> </em>for yield contributing characters. These two progenies showed highest mean values than the other progenies. It exhibited more mean values than the parents for the characters viz., Cob length, Cob diameter, Cob weight, Yield per plant and 100 grain weight. Based on the mean values progenies UMI 79/936-C1-7-7-7-S80 and UMI 79/936-C1-7-7-7-92 confirmed as the best progenies.
