Abstract

                                The building up of a wide and comprehensive collection of crop varieties is well recognised as an essential prerequisite to modern plant breeding work. The next step is to study the diversity in respect of quantitative characters, which are of economic importance, with a view to break up the observed variation in these characters into heritable and non-heritable components. The present investigation was carried out to assess the variability among certain barley types with respect to a few quantitative characters which appear to be related with yield. It was also considered worth while to determine the relative importance of these quantitative characters with the help of certain genetic parameters like co-efficient of variability, heritability, genetic advance, etc.
