Abstract
Noura Mohammed Taha Mohammed Ali: Effect of Some Mutagenic Agents on Garlic Production. Unpublished M.Sc. Thesis, Department of Horticulture, Faculty of Agriculture, Ain Shams University, 2009.
In spite of garlic is one of the oldest crops under Egyptian cultivation, but productivity is very settled from a long time. This settlement is due to sexual sterility of garlic, hence it does not set seeds. Thus, induced mutation and clonal selection proved as an effective way for improving garlic crop. So, the aim of this work was to study the mutagenesis effect of gamma irradiation (at doses 2.5, 5 and 10 Gy), EMS (at concentrations 15 and 20 mM) and sodium azide (at concentrations 0.1, 0.2 and 0.3 g/l) on two garlic cultivars, Balady and Seds 40. The results indicated that in M1 generation the values of most studied traits were decreased at the high doses and high concentrations of gamma-rays and S.A. compared with control plants. In M2-generation, most of the studied characters showed higher rates when lower concentrations and lower doses were used, therefore, selection in this generation could be carried out.
