Variability studies of weeds in agricultural fields are useful in promoting integrated management measures. It was found that a higher variability of any species can be controlled more easily by various methods. And if C. intybus species was a significant spread in agricultural fields, while variability information they are fewer. Weed, being adapted white luvicsoil the south of the country has shown that inflorescence have diameters between 3 and 5 cm, with a ligulae flower number between 13 and 25 pieces. Their modal values were 3.8-4.0 cm in diameter and 15-16 ligulae flowers number in head (capitula). Fruit s (achene) were formed in a number between 1 and 15 in the head, with a length between 1.5 and 2.6 mm, and the width between 0.7 and 1.1 mm. Modal values of these dimensions of fruits were 7-9 pieces/ head, with 1.9-2.0 length and 0.9 mm width. Correlations between the various characters showed positive results, and that means the plant have a good adaptation to the various vegetation conditions.
