Abstract:
Seventy genotypes of Brassicanapus were evaluated to study the variability,
correlation, path analysis and genetic diversity based on agro-morphological
traits at Sher-e-Bangla Agricultural University, Dhaka during November 2016
to February 2017. Significant variations were observed among the genotypes
for all the traits studied. Considering genetic parameters, high GCV values
were observed for number of primary branches per plant, number of secondary
braches per plant and seed yield per plant. High heritability values with high
genetic advances in percent mean were obtained for number of secondary
branches per plant, number of siliquae per plant, number of seeds per siliqua,
1000 seed weight and seed yield per plant. Correlation studies revealed
significant positive association of seed yield per plant with days to 50%
flowering and siliquae per plant at both genotypic and phenotypic levels. Path
coefficient indicated positive direct contribution towards days to flowering,
siliquae per plant, seeds per siliqua and 1000 seed weight. The genotypes were
grouped into five clusters. Cluster III contained the maximum number of
genotypes
performance the genotype of G4, G43, G54, G31, G41, G14 and G59 might be
used as open pollinated verities by further purification and need to further
performance studies and stability test; and could be used as parents in future
hybridization program.
