DUS characterization of various sorghum genotypes (Sorghum bicolor L. Moench) on the basis of midrib colour

Abstract

The present study was conducted on 25 sorghum genotypes grown in Randomized Block Design during Kharif 2015 to evaluate, categorize and classify them for fodder yield and quality traits. Registration and protection can be granted to a variety only if it conforms to the criteria of Distinctness, Uniformity and Stability. New variety has to Distinct-Uniform-Stable (DUS) in its characteristics. Observations were recorded on eighteen variables involving morphological, quality. Out of 25 genotypes, nine genotypes were grouped under yellow green and remaining sixteen genotypes were under greyed purple. Ten genotypes were without stigma anthocyanin colouration and remaining fifteen genotypes had stigma anthocyanin colouration. On the basis of total plant height, stem girth, number of tillers, number of leaves, green fodder yield and dry fodder yield genotypes were classified and genotype CSV 21F, HJ 260, IS 2205, S 490, S 651, SSG 59-3 showed maximum plant height, number of leaves, number of tillers, stem girth, green fodder yield and dry fodder yield.
