SUMMARY

The present investigation was conducted on 49 different sorghum genotypes grown in randomized block design during kharif 2018 to evaluate, categorize and classify them on the basis of various DUS parameters. A total of 11 different qualitative traits were characterized as per the guidelines for the conduct of test for Distinctiveness, Uniformity and Stability on sorghum by PPV & FRA, GOI. The observations were taken on five randomly selected plants of each genotype for the following characters viz., anthocyanin coloration of coleoptiles and leaf sheath, midrib colour of leaf and flag leaf, colour of dry anther and glume, panicle shape and density, awn-ness, grain luster and colour. Results revealed that out of 49 genotypes, 11 genotypes were grouped under yellow green and remaining 38 under greyed purple on the basis of anthocyanin colouration of coleoptile. On leaf sheath anthocyanin coloration basis, 15 genotypes were greyed purple and 34 were yellow green. Thirty two genotypes had greyed yellow and 17 genotypes had white leaf mid rib colour. Mid rib coloration of flag leaf in 21 genotypes was white and in 38 genotypes it was found to be yellow green. Presence of awn was observed in 14 genotypes. On the basis of anther colour of dry anther, 17, 1, 8 and 23 genotypes were categorized into four groups viz., yellow orange, orange, orange red and greyed orange, respectively. Whereas, glume colour in genotypes were classified into five categories viz., green white (10), yellow white (13), greyed yellow (7), greyed orange (13) and greyed purple (6). Five different categories of panicle density viz., very loose (3), loose (11), semi loose (16), semi compact (18) and compact (1) were observed at maturity in these sorghum genotypes. On the basis of panicle shape eighteen genotypes had symmetrical, eight had panicle broader in lower part, ten had reverse pyramidal and thirteen had panicle broader in upper part. Twenty seven genotypes had lustrous grain and 22 genotypes had non lustrous grain. Grain colour varied among genotypes viz. white (12), yellow white (26), yellow orange (6), and greyed orange (5). The outcome of these traits tells us about the genetic architecture of the genotypes and their interaction within a specified environment for further improvement.
