Abstract
The present investigation entitled “Genetic Divergence in Sorghum [Sorghum
bicolor (L.) Moench]” was carried out with 1700 germplasm lines along with4 checks
i.e. CSV17, CSV20, CSV27 and CSV21F provided by National Bureau of Plant
Genetic Resources (NBPGR) through ICAR- Indian Institute of Millet Research
(IIMR) Hyderabad. The experiment was laid out in augmented RBD with 60
replications during Kharif 2015 at Instructional Farm, Rajasthan College of
Agriculture, Udaipur. Observations were recorded for 26 characters i.e. 17 qualitative
and 9 quantitative characters on five competitive plants selected at random for each
germplasm lines except early vigour and days to 50 percent flowering which were
recorded on whole plot basis. Availability of genotypes in different replication at the
time of observations was not conform on account of germinations and shoot fly dead
hearts therefore, data were analysed in augmented CRD. Analysis of variance
revealed significant difference between genotypes for 9 quantitative characters.
Variability parameters, correlations coefficients, path coefficients, MANOVA and
genetic divergence were studied using these 9 characters.
Majority of the accessions showed good early plant vigour (52.7 %), dark
green leaf (96.1 %), non-tan leaf sheath pigmentation (94.4 %), drooping leaves
(100 %), green midrib colour (52.5 %), non senescence (91.8 %), compact panicle
density (53.6 %), elliptical panicle shape (34.9 %), straw glume colour (35.3 %), ½
glume coverage (42.8 %), presence of awns (89.2 %), creamy straw seed (40.6 %),
sub lenticular round but flat from other side grain shape (35.0 %), medium seed size
(35.2 %), non-lustrous seed (93.8 %), intermediate endosperm texture (44.8 %) and
durra race (30.0 %).
