STUDIES OF INDUCED MUTATIONS IN PEAS

GELINimportant advantage, because leaf-spotting can be easily and exactly measured.Leaf-spotting occurs in all plant families hitherto tested as an effect of mutagenic treatment, but in some plants, especially in monocotyledonous plants, it is difficult to measure.It seems to present a very simple and useful means of measuring mutagenic effect on large materials and within a reasonable time from treatment, 2-4 weeks, at the same time as toxicity can be measured by characters like germination, growth inhibition and so on.(BLIXT et al., 1964; BLIXT, 1965a, 1965 b; BLIXT and GELIN,
