Studies were carried out to estimate the extent of genetic
variability in some cultivated genotypes of sweet sorghum (sorghum
bicolor L Moench). Thirty genotypes were evaluated in 2011 rainy
season across two locations, to obtain more information on their
genetic and morphological diversity. Significant mean squares were
obtained for 10 traits in the individual analysis and also for the
combined analysis across locations, suggesting that this sweet
sorghum population was highly variable for some of the characters
and as such will respond to selection. Mean performances for the
combined analysis identified ICSV 93046, (SW DAURA 06-5-2 &ICSV700),
SPV 422, ICSV700, (SW DAURA 06-5-2 & 38A x NR71182), SW DAURA
06-5-2, (SW DAURA 06-5-4 & E36-1), 38A*NR71182, and (SW KEBBI 07-5 &
SPV 422) as the best genotypes in terms of days to 50% flowering,
plant height, stem thickness, number of nodes, number of leaves,
panicle weight, 1000 grain weight, grain yield and sugar content.
