Description The objective of present investigation was to for characterize 20 genotypes of sorghum
{Sorghum bicolor (L.) moench} on the basis of 33 morphological characters provided by PPV & FRA
for DUS testing in sorghum. Results revealed that maximum variation was found among genotypes on
the basis of glume colour in which genotypes G 46, HC 308, HJ 513 had green white, IS 3237, SSG 9,
HC 171 had yellow white, SSG 59-3, COFS 29 had grayed purple, S 437-1, SGL-87, S 540-S, SSG
(PSSG) had grayed yellow and remaining seven genotypes had grayed orange glume colour. Whereas,
glume length varied from very short (three genotypes), short (six genotypes), medium (six genotypes),
long (four genotypes) to very long genotype (COFS 29). On the basis of seedling anthocyanin
colouration of coleoptiles and leaf sheath anthocyanin colouration of coleoptiles two groups were made
i.e. yellow green (four genotypes) and grayed purple (sixteen genotypes). All genotypes showed simlar
expression in both traits. In case of width of blade, genotype COFS 29 had Short (8 cm) width of blade. Genotypes were grouped into four groups viz., short (six genotypes),
medium (eight genotypes), long (three genotypes) and very long (three genotypes) on the basis of
panicle length without peduncle. Whereas, panicle density at maturity (ear head compactness) varied
from very short (four genotypes), loose (three genotypes), semi loose (four genotypes), semi compact
(eight genotypes) to compact in COFS 29. On the basis of panicle length of branches, genotypes were
divided into four groups, two genotypes IS 3237 and HC 136 were short (15.1 cm). In case of neck of panicle visible above sheath, genotypes were divided
into five groups viz., absent or very short (eight genotypes), short (four genotypes), medium (three
genotypes), long (two genotypes) and very long (three genotypes). On the basis of grain texture of
endosperm, genotypes were divided into four categories, genotypes SSG 9 and COFS 29 were vitreous,
seven genotypes were ¾ vitreous, eight genotypes were ½ vitreous, and three genotypes G 46, SSG
5(22) and HJ 513 were ¾ farinaceous. Classification of genotypes on the basis of DUS traits provided
identification of key characteristics of various genotypes. Broad sense heritability, GCV, PCV,
correlations and path analysis were also carried out in these 20 genotypes.
