Seeds of <I>Linum usitatissimum</I> L. were treated by gamma rays at different doses such as 100, 200, 300, 400 and 500 Gys from Co-60 source alongwith control and the occurrence of pollen germination and pollen tube growth were reported at various doses of gamma rays along with control. The impact of gamma rays on pollen-fertility, pollen germination and pollen tube growth has also been investigated. The percentage of pollen germination and pollen fertility increases upto 300 Gy and at the treatment dose of 400 Gy and 500 Gy, a reduction in pollen viability and decrease in percentage of pollen germination has been noticed. A decrease in pollen tube length has also been noticed at the dose of 400 and 500 Gys.
