GENETICS AND PLANT BREEDING
The experiment was conducted with twenty six F3 progenies of Brassica napus at
the experimental farm of Sher-e-Bangla Agricultural University, Dhaka- I 207,
during November. 2011 to March, 2012 to study the variability, correlation and
path analysis in F3 population of Brassica napes The phenotypic variances were
higher than the genotypic variances. Least genotypic and phenotypie variances
was observed among all the parental genotypes and their F3 progenies for all the
characters studied except for siliquae per plant. The high GCV value was observed
for secondary branches per plant. The number of secondary branches per plant
also showed high heritability with high genetic advance in percent of mean. Based
on the variability and Yield per plant had significant positive association with
number of primary branches per plant, number of siliquae per plant. Siliqua
length, Seed per Siliqua and 1000 seed weight. Path co-efficient analysis revealed
that days to 50% flowering, plant hieght, number of secondary branches per plant.
Siliqua per plant siliqua length, seeds per siliqua and thousand seed weight had
the positive direct effect on yield per plant. Number of siliqua per plant had the
hight positive direct effect on yield per plant. Genotype 9 and genotype 16 were
tound as short durated lines in the experiment.
