Investigation of mutation variability in lentil (Lens culinaris Medik)

The effects of different doses and mutagens on field germination, survivability and sterility in M1 plants, and the frequency of mutations and mutation types in the M2 generation of lentil were influenced by environmental factors. Under unfavourable conditions, lower treatment doses resulted in lethality of the mutagens. The percentage sterility was higher and the spectrum of changes widest in combined gamma ray and EMS treatment. The spectrum of changes in favourable years was more pronounced, but most of the changes were of little economic value. Of the varieties tested, small seeded Tadjikskaya 95 had the highest radio-resistance. (author). 6 refs, 2 figs, 1 tab
