利用γ射线25、50、75和100千伦处理亚麻品种Neelum的种子,剂量率为15千伦/分。在剂量为50千伦处理的M_2中,选到持有狭叶和茎秆长度变短的早熟突变植株。在M_3-M_6中,研究矮生突变体PKM查明其开花较对照平均早30天。而其株高仅为对照的一半,千粒重高,产量较低。由于其收获期可比当地标准品种提早六星期,因而是一个有经济价值的突变体。尽管这种 Seeds of flax species Neelum were treated with gamma rays at 25, 50, 75 and 100 keratoms at a dose rate of 15 kph. M_2, which had been treated at 50 Kilon dose, was selected to be a precocious mutant with short leaves and stalks. In M_3-M_6, the study of the dwarf mutant PKM found that its flowering compared with the control average of 30 days. The plant height was only half of the control, with a high grain weight and lower yield. It is an economically viable mutant due to its harvest period of six weeks earlier than the local standard. Despite this
