ABSTRACT
The study was conducted at the Botanical Research Field, University of Rajshahi, Rajshahi, Bangladesh three consecutive rabi season in 2009, 2010 and 2011. The basic preconditions for yield improvement are presence of genetic variability in genetic stock and information of inheritance and inter relationship of the yield components, along with their relative influence on each other. These parameters are differing in different genetic stocks developed by the breeders, which need a critical study. The present study was conducted with the view to expose the genetic variability, heritability, genetic advance and correlation analysis in chickpea. Study exposed presence of sufficient variability with low heritability for most of the yield components. Correlation studies indicated that Number of pods per plant (NPd/P), Pod weight per plant (PdW/P) and Number of seed per plant (NS/P) could be useful as selection indices for development of high yielding genotypes of chickpea.
Keywords: Variability, Heritability, Correlation coefficient and Chickpea.
