Genetic Variability, Correlation and Path Analysis in Advanced Lines of Rapeseed (Brassica Napus L.) for Yield Components

Abstract

ABSTRACT The present research was carried out to determine the best selection criteria for yield improvement in rapeseed (Brassica napus L.). Nine genotypes of Brassica napus were sown at Oilseeds Research Institute, Faisalabad, during the years 2011- 2012, to evaluate the means and components of variability (genotypic and phenotypic), heritability (h2 B.S), correlation (genotypic and phenotypic) and path analysis for yield and various yield components. At phenotypic and genotypic level, seed yield/plant h…
