Effect of Sodium Azide on Seed Germination and Related Agro-Metrical Traits in M, Lentil (Lens culinaris Medik.) Generation

摘要

Seeds of two lentil (Lens culinaris Medik.) varieties L4594 and L4147 were subjected to different concentrations of sodium azide (SA). Effects of chemical mutagen were evaluated for seed germination, seedling height and number of rootlets, in both the lentil varieties under laboratory conditions. Seed germination, seedling survival and some other agronomical traits viz. days to flowering, pollen fertility, plant height, number of branches/plant and pod/plant were also evaluated under field conditions. Reduction in germination percentage, seedling growth, number of rootlets, plant height and pollen fertility were observed in all the treatments. The variety L4147 in all the treatments except the control exhibited zero seedling survival on day 25 under field conditions. Number of branches and pods / plant significantly increased at 0.1% SA. Delay in days to flowering was exhibited in all the treatments. Both the parental varieties differed significantly between themselves for both percentage seed germination, seedling height seedling survival and most of the characters at seedling stage for SA treatments. Variances among treatments were also significantly high.
