    VARIABILITY, CORRELATION AND PATH ANALYSIS IN F3 POPULATION OF Brassica napus
    (Department of Genetics and Plant Breeding, Sher-e-Bangla Agricultural University, Dhaka-1207, 2013-06) BEGUM, SHAHANA
    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.
