Description :
This study was conducted to investigate the effect of seed irradiation on the seed germination and seedling growth characteristics of two varieties of Capsicum annum. variety Pusa Jwala and variety Bhiwapuri. Seeds were irradiated with 100,200,300,350& 400Gy gamma rays using Cobalt-60. Percentage of seed germination and growth traits such as seedling height, root length and leaf number were observed. Results showed that irradiation dose at 400Gy had highest lethal effect. Germination percentage in both the varieties decreased with increasing dosage of gamma irradiation from 200Gy to 400Gy in petri-dish method and 100Gy to 400Gy in raised bed method. Growth in terms of seedling height and root length decreased with increasing doses of gamma irradiation in both the varieties. Leaf number significantly decreased in 300, 350 and 400Gy of Bhiwapuri and in 350 and 400Gy treatments of Pusa Jwala.
