Study of Genetic Variation and Association among Characters in Tomato Genotypes

The study was conducted to determine the genetic diversity and correlation among the different traits in tomato germplasm. ninety-seven landraces collected from iğdır city (east anatolian region) of turkey and north-west of iran, along with three commercial cultivars were studied during two years. tomato genotypes showed genetic diversity in all the studied characters. fruit shape of genotypes contained flattened, slightly flattened, rounded, cylindrical, cordate, ovate, obovate, pyriform and obcordate. in fruit color, red, dark red, orange, yellow and in fruit size, very small, small, intermediate and large were observed. correlation analysis showed the genotypes with high yield, had large fruit, firm fruit, high blossom end rot and sun scald, small plant size, sparse foliage density, low seed amount/fruit size. cluster analysis classified genotypes in six groups, so that genotypes with different vegetative and generative charactreristics were located separate groups
