Abstract
One of the most important problems for the field-grown Ayaş tomato (Solanum lycopersicum
Ayas population), which is preferred for consumption in Central Anatolia because of its
aromatic taste, is that the shelf life is short because of insufficient fruit firmness. Therefore, a
study was initiated to develop high-quality lines and variety candidates through mutation
breeding in the current Ayaş population. In this study, the effective mutation dose (EMD50)
was found to be 150 Gy for seeds using a Cobalt-60 gamma ray source. The main mutant
population was generated by applying EMD50. During the study, mutant lines selected by
following the classical mutation breeding stages were evaluated in terms of yield and quality
traits (antioxidant content, total soluble solid amount, fruit firmness, Brix, etc.) starting from
the M4 stage. One of our aims was to determine and improve the phytonutrient content of
field-grown tomatoes. The fruits of selected lines at the M4 stage were extracted by liquidliquid partition and accelerated solvent extraction techniques and analyzed by High
Performance Liquid Chromatography (HPLC) in this study. It was found that 28 of the 29
mutant lines were significantly different from the control and mutant lines. Mutant lines 9-22,
8-90, 8-135, and 8-127 were determined to be the most promising for commercialization.
