Effect on some characteristics of M1 plants of Three Hungarian vetch (Vicia pannonica Crantz.) the application of different doses of gamma Irr adiation

Abstract

Th e ai m of th e stud y was to determin e th e mos t efficien t dos e of gamm a irradiation for th e mutationbreeding and in order to be a variation of wide, the effects of irradiation with gamma doses on some plantcharacteristic s an d to compare thes e effects with non -irradiated control (0 Gy ) of Hungarian vetc h (Vici apannonica Crantz.).In the stud y, morphological, biological and agricultural characteristics of M1 plants of three Hungarianvetch cultivars (Tarmbeyazı -98, Anadolupembesi -2002 and Oğuz -2002) obtained by irradiation of the seedswith di fferent doses of cobalt 60 gamma rays (0, 40, 60, 80 and 100 Gy) were studied. The laboratory andfield experiments were arranged in the split plot design with.This experiment was carried out at Ankara/Haymana Field Crops Central Research Institute (TARM) andAplication Far m an d i n th e laboratory. I n th e presen t stud y conducted durin g th e year of 201 0 underAnkara/Hayman a ecological condition s an d i n laboratory, seedlin g germination rate of th e seeds , height,seedling fresh weight, seedling dry weight, emergence rate, flowering period, plant height, height of mainstem, thickness of main stem, number of main branches per plant, number of pods per plant were recorded. The results of the study showed that were negatively influenced the application of gamma irradiation by80 and 100 Gy doses of gamma rays, germination rate of the seeds, seedling height, seedling dry weight,seedling fresh weight, seedling of root height, emergence rate, plant height, height of main stem, number ofmain branches per plant, number of pods per plant and number of seeds per pod.According to LD 5 0 application, It was determined that most efficient of dose especially 80 and 100 Gygamma irradiation of M1 generations.
