Abstract :
The grain productivity of rabi sorghum in India
is very low (750 kg/ha) compared to kharif sorghum. To
enhance grain quality, productivity and shoot fly tolerance of
rabi sorghum, prior information on the nature and
magnitude of genetic diversity present in germplasm
collection is a pre-requisite. One hundred rabi sorghum
germplasm lines of diverse origin were used to estimate
genetic diversity. Among the 15 quantitative traits studied,
the highest contribution towards the divergence was by plant
height, Days to flowering, panicle weight, panicle length,
number of primaries per panicle, dead heart percentage and
grain yield were also contributed towards diversity. The
genotypes were grouped into 23 clusters. Clustering pattern
obtained in the present study indicates that no relationship
was observed between the geographical diversity and genetic
diversity.
