Behavior of “Barna”, cultivar of potato (Solanum tuberosum L.) at different doses of gamma rays Cobalt-60 source
Main Article Content
Abstract
(Solanum tuberosum L.). Seed-tubers of the cultivar “Barna” imported from Holland with a weight (20 g), with six treatments: five irradiation doses 10, 20, 30, 40, 50 Gy and one non-irradiated control (0 Gy). In this study a strong reduction of plant emergence was observed, as the dose was progressively increased the emergency decreased. It is suggested not to apply doses higher than 50 Gy in seed-tubers,
for works directed to the use of radiomutagenesis in the potato breeding of the potato, due to the negative effect in the emergency and in other important characters. Doses applied to potato seed tubers between 20 and 40 Gy could be evidence of induction of mutation, while at 10 Gy a stimulation of flowering was observed in the cultivar “Barna”.
