dc.description.abstractMutation breeding is one of the favorable techniques to the production of new cultivars and lines. But the determination of mutagen type and their appropriate doses the most important points in mutagenesis due to lethality in living organism. In the present study, the winter squash and pumpkin seeds were irradiated with a Co-60 source at five gamma ray doses (50, 100, 200, 300 and 400 Gy). Radiobiological effects of the gamma rays were investigated in root tip cells of germinated seeds in the M-0 (irradiated seeds) and M-1 generations of winter squash and pumpkin lines via mitotic index (MI), mitotic abnormalities (MA) (total abnormal cell, abnormality percentage, and chromosomal aberrations). Seeds irradiated with doses of up to 200 Gy exhibited similar MI and MA as non-irradiated control seeds. While cell division sharply interrupted and reduced, MA gradually increased at 300 Gy and 400 Gy gamma ray doses. M-0 showed the greater decrease in MI and increase in MA than M-1 generation.en_US
