Comparison Some Fruit Characteristics of Eggplant Population with Their Selfing Lines

Abstract

The aim of this research was to compare the some fruit characteristics of eggplant population with their selfing lines. The selection programme was conducted to get promising breeding lines from eggplant population of Sanliurfa. The study included 6 population (Surtepe, Altinova, Magarali, Ugurlu, Mezra and Keskince) collected from different villages of Sanliurfa where mostly growing. In the first year, 20 lines were obtained from the populations by selection program using selfing method. The scale taken from UPOV, applied in both population and selfing lines to determine the characteristics of fruit. Fruit characteristics were compared between in each population with its selfing lines, such as ratio of fruit length/diameter, fruit curvature, shape of apex, level of glossiness on fruit skin, length of fruit stalk, size of calyx, spinyness of calyx, intensity of anthocyanin below calyx, length of flower stalk, purple level of flower. All features were evaluated according to statistical values so some of the lines had significant differences from its population. Mezra 1, Mezra 4 and Mezra 5 had significant difference from its population for ratio of fruit length/diameter; Surtepe 1, Altinova 4, Mezra 1, 4, 5 and Mezra 6, lines had significant differences from the population for shape of apex. In level of glossiness on fruit skin Altinova 2, 3 and Altinova 4 lines and Mezra 4, Keskince 3 and 5 lines had significant difference from the population in statistical means. Most of the characterization of lines can be certain parameters to develop new varieties. And also Rankit-Weighted Method was applied to the lines to choose the best line or lines for some important fruit characteristics preferred by local consumer. Surtepe 1, Surtepe 2, Mezra 5 and Keskince 3 breeding lines got 750 and over score, so it will be essential to carry on the research with these lines.
