Abstract

In the present investigation, 122 landrace collections were evaluated to have en idea of the genetic variability in them. Analysis of variance revealed highly significant variancos in landraces for all the traits. The widest range was observed for plant height, grain yield, 1000 grain weight, ear length and grain density. The phenotypic and genotypic coefficient of variation were highest for effective tiller number followed by those for grain yield and ear length. Heritability was very high for days to flower, plant height, effective tiller number, leal length, ear length, ear girth, grain density and 1000 grain weight. It was comparatively medium to high for stem thickness, leaf width and grain yield and was low for number of nodes. Maximum expected genetic advance was observed for tiller number followed by grain yield, and ear length. Consistency in estimates of heritability and genetic advance was exhibited by tiller number, grain yield and ear length.
