Effects of Drought on Yield and Pomological Features of Wild and Domestic Turkish Watermelon Genotypes

This project was carried out between 2007 and 2008. The aim of this project was to determine drought tolerance of native and wild watermelon genotypes. The materials of this project supported by TUBITAK (Turkish Scientific and Technological Research Council) were selected previous project which was finished at 2006. Thirty-two materials were used at this experiment. Yield, TSSC, mean fruit weight, mean fruit height, fruit diameter, mean fruit rind thickness and amount of seed at each fruit and as pomological treatments were tested at two years. The project had three subjects in order to determine drought tolerance at selected genotypes. The first is zero irrigation for artificial drought (I-0), the second is full irrigation (I-1) and the last is half amount of the full irrigation (I-2). Fifteen genotypes were determined as tolerant and seventeen genotypes were determined as intolerant.
