Variability, correlation and path co-efficient studies in interspecific crosses (Avena sativa × Avena sterilis) of oat

Genetic variability, correlation and path coefficients for fifteen agro-morphological traits were studied on 100 oat lines including two checks. Genotypic phenotypic of variation high leaf number per tiller weight panicle. Traits such as plant, tiller, panicle, stem width, individual plant yield, length internode thousand seed showed heritability accompanied by genetic advance indicating that these characters can be enhanced simple selection. Association studies revealed a positively significant association yield with weight, floret spikelet height at the level. Path analysis disclosed width flag leaf, exhibited positive direct effect yield. Among characters, panicle possessed effect. So, used creation ideotypes selecting will worthwhile higher Keywords: Oat, correlation,  Path Coefficient, heritability, Ideotype
