Genetic characterization for seed yield, its contributing traits and oil content in Ajwain (Trachyspermum ammi L.) over the environments

For present study experimental material consisted of 25 elite genotypes of ajwain. Observation was recorded on 11 quantitative traits in ajwain. High estimates of heritability (broad sense) were obtained for oil content and seeds per umbelet. The magnitude of PCV as expected was greater than the corresponding GCV for all the characters indicating importance of environment in expression of characters. Oil content, number of umbels per plant and seeds per umbelet showed high GCV and heritability coupled with high genetic advance as per cent of mean which revealed that these three traits might be under control of additive gene effects and therefore they are more reliable for effective selection. | Genetic characterization for seed yield its contributing traits and oil content in Ajwain Trachyspermum ammi L. over the environments
