| ABSTRACT |
| Forty eight linseed (Linum usitatissimum L.) genotypes were evaluated during rabi, 2010-11 for eleven quantitative traits to examine the nature and magnitude of variability, heritability (h 2=broad sense) and genetic advance. Analysis of variance revealed that the differences among forty eight genotypes were significant for all the characters. Knowledge of selection effect on positive or negative changes of a character under improvement is of paramount importance for the success of any plant breeding program, and helps the selection of a desirable breeding method. Heritability and genetic advance are important selection parameters, and selection success is a reflectance of selection response. The characters number of branches per plant, number of capsules per plant, seed yield per plant, seed yield per plot, omega-6-fatty acid and secoisolariciresinol diglucoside (SDG) fatty acid exhibited high genotypic coefficient of variation (GCV) and phenotypic coefficient of variation (PCV). Small differences between GCV and PCV were recorded for all the characters studied which indicated less influence of environment on these characters. The characters plant height, number of branches per plant, number of capsules per plant, 1000 seed weight, yield per plant, omega-6-fatty acid and SDG fatty acid exhibited high heritability coupled with high genetic advance indicating that simple selection could be effective for improving these characters |
