Abstract:

Buckwheat is an important pseudo-cereal with a better nutritional and medicinal value than many common cereals. The present investigation was undertaken to estimate the phenotypic coefficient of variation (PCV) and genetic coefficient of variation (GCV), heritability and genetic advance as per cent mean. Fifty-four diverse buckwheat genotypes (involving exotic, indigenous and local collection) were evaluated in a replicated completely randomized block design during Kharif 2017. Analysis of variance revealed highly significant differences between the genotypes for all characters studied suggesting the presence of adequate variability for selection. Moderate PCV and GCV coupled with high heritability were recorded for days to 50 per cent flowering while, high genotypic and phenotypic coefficients of variation coupled with high heritability and genetic advance as per cent mean were observed for seed yield and number of secondary branches indicating the more additive gene action hence the selection for these traits could be effective. However, days to maturity exhibited low PCV, GCV and genetic advance indicating selection will be ineffective for such traits.


Keywords: Pseudo-cereal, Variability, GCV, PCV, Heritability, Genetic advance.
