Effect of Gamma radiation on seed germination of Linseed

Abstract Linseed is also known as flaxseed belongs to the family Linaceae. The gamma radiation’s impact on developing new linseed mutants. The seeds of Linum usitatissimum L. (Linseed) var. PKV NL 260 were selected and used for subsequent investigations. Seeds were procured from Dr. Panjabarao Deshmukh Krishi Vidyappeth, Akola, Maharashtra and irradiated from the Department of Nuclear Chemistry Division, Department of Chemistry, University of Pune. Seeds were irradiated with various doses 100 Gy, 200 Gy, 300 Gy and 400 Grays of gamma rays and untreated (control) to induce mutation. Healthy, dry, and uniform seeds were treated with different doses of gamma rays like 100 Gy, 200 Gy, 300 Gy and 400 Gy. This investigation aimed to develop improved yield mutants lines through induced mutation in linseed (Linum usitatissimum L. var. PKV NL 260). Germination parameters such as seed germination percentage, seedling height, and seedling injury were studied. Seed germination percentage of control was 87 %. The seed germination percentage gradually decreased from lower to higher doses in the given gamma ray treatments. In conclusion, the use of physical mutagens (gamma radiation) successfully induced M1 Biological parameters.
