ABSTRACT
Pakistan spends a major part of expenditure on import of the edible oil owing to significant rise in demand. Main aim of the study was to analyze the 18 genotypes of Brassica juncea L. for correlation and their path co-efficient analysis. Mean square for five traits was constructed which was highly significant except plant height. Correlation in plant’s height and branches, days required for flowering and days required for maturity was positive at genotypic as well as phenotypic levels. Correlation between numbers of branches and days required for flowering was positive, while negative association of branches’ number was observed with days required for maturity and the obtained yield of a plant. Positive association was expressed between days required for flowering and days required for maturity. Negative association was observed in days required for flowering and the obtained yield from a plant. Positive correlation was observed in days required for maturity and the obtained yield from a plant. The direct effect of plant’s height on obtained yield was positive and indirect effects through days required for flowering was positive and the indirect negative effects were contributed through branches’ numbers (-5.54) and days required for maturity (12.27). Number of Branches have negative direct effect on the obtained plant’s yield. Indirect effects posed by plant’s height, days required for flowering and days required for maturity were positive. The present study shows that the plant’s height is positively correlated with the other assessed traits and these can widely be used as priority for selecting the genotypes with higher yield.
