Abstract/Contents:"Using the material of Festuca arundinacea Airei III, suitable induced mutation doses and shape and property variation were studied by using 60Co γ-ray radiation to irradiate both dry seeds and differential seeding. The results showed that emergence and survival rates of individual plants decreased with increases in irradiation dosages. The appropriate induced mutation dosage was found to be from 100Gy to 150Gy for dry seeds and 20Gy to 25Gy for differential seeding. Radiation modern has an obvious variation in both plant shape and drought (cold) resistance character, the variation frequencies were 1.52% to 8.33% and 1.52% to 1.85% respectively. 60Co γ-rays irradiation is more likely to obtain mutation with plants that have smaller and slimmer leaves with the character of drought (frigidity) resistance. Mutant variations were found at the DNA level through the use of RAPD analyzing."
