Abstract :

The present account deals with the mutagenic impact of 6–aminopurine (6–AP) on the qualitative and quantitative traits of Linum usitatissimum L. The experiment was conducted in 2015–16 cropping season to study the mutagenic effect of the mutagen. The seeds were treated with different concentrations of 6–AP i.e 0.10%, 0.25%, 0.50%, 0.75% and 1.0%. Mutation was reported in terms of morphological traits as well as high phenotypic alterations were recorded in plant height, number of seeds/plant, number of capsules/plant, number of seed/capsule and number of anches/plant while compå it with control. According to the observations, the lower doses of mutagen were found to be more effective as compared to the higher doses. Therefore, low concentrations would be beneficial for plant eeders to induce desirable mutations for improving other useful characters in crop plants.
