Research Notes : India : Induced variability for quantitative characters
Is Version Of
Gamma rays were used to induce the genetic variability for different quantitative characters in Bragg and Type-49 varieties of soybean. Materials and methods : Samples of 200 seeds of Bragg and Type-49 soybeans were irradiated with 10 krad, 15 krad and 20 krad doses of gamma rays, a week before planting time. These irradiated seeds, along with the unirradiated controls, were planted in split-plot design with three replications.
