Abstract:
A field experiment was conducted with 31 8C1F3 genotypes of Brassica tzapzis i. at the
experimental field of Sher-.e-Bangla Agricultural University, Dhaka to study the genetic
diversity, variability, correlation and path coefficient analysis during November 2012 to
March 2013. The genotypes were found significantly variable for all the characters.
Comparatively phcnotypic variances were higher than the genotypic variances for all the
characters studied. The high CCV value was observed for number of secondary branches
per plant. Plant height, number primary branches per plant, days to 50% flowering, and
seed yield per plant showed high broad base heritability. The significant positive
correlation with seed yield per plant was found in plant height, the number primary
branches per plant, number of secondary branches per plant and number of siliqua per
plant. Path coefficient analysis revealed that number primary branches per plant, number
of secondary branches per plant and number of siliqua per plant had the positive direct
effect on yield per plant. The genotypes were grouped into five clusters. The highest inter
cluster distance was observed between cluster I and V and the maximum intra cluster
distance was found in cluster IV. Considering group distance and other agronomic
performance genotypes Cl. 62, 03, 020, and 028 might be suggested for future
hybridization program.
