Genetic variability and selection parameter for yield and its components in linseed (Linum usitatissimum L.)

An experiment consisting 60 genotypes of linseed was conducted at Research Farm P. G. College Ghazipur during two years 2007-8 and 2008-9 in three micro environments results showed high level variability for pooled data all the characters. Highest PCV GCV were recorded biological yield per plant followed by capsules seed plant. It lower days to maturity oil content. High heritability broad sense characters except which moderate heritability. Genetic advance a number Other low genetic indicating role both additive non-additive genes. advancement 139.6% over base population expected capsule (56.30%). Seed had about 50% improvement mean. positive significant correlation with flowering, maturity, tillers plant, branches seeds Simple selection method would be more appropriate improving yield.
