DES Induced variations for Economic Traits in Broad bean (Vicia faba L.)

Download this article as: 

Seeds of broad bean (Vicia faba L.) var. major were treated with 0.25%, 0.50%, 0.75%, concentrations of diethyl sulphate (DES) to induce variability in seven economic traits viz. plant height, days to flowering, days to maturity, pods/plant, seeds/pod, seeds/plant and 100-seeds weight. The direction of shift in mean values for plant height indicated that negative micromutations out-weighed the positive ones. While as for days to flowering, days to maturity, pods/plant seeds/pod, seeds/plant and 100 seeds weight shift of mean was recorded both in positive and negative direction. Coefficient of variation was recorded to be higher in mutagen treated populations.
