VARIATION FOR QUANTITATIVE TRAITS IN OAT GERMPLASM

Abstract

Evaluation of 2576 oat germplasm in augmented design showed high range and
per cent range of variation fOr grains/panicle, leaf width, 100-groat and grain
weight, and leaf length. Panicle length, seed width, plant height and seed length
exhibited medium range as well as per cent range of variation, howell9r, less
variations were observed for 50 per cent heading and maturity. Classification of
germplasm based on frequency distribution into different classes r9119aled that
majority of the genotypes, concentrated towards mean. Both the extreme types
of classes consisted of less number of genotypes
