Determination of the Yield and Yield Components of Narbon Vetch (Vicia narbonensis L.) Lines Grown in Spring

Fifteen narbon vetch (Vicia narbonensis L.) lines obtained from ICARDA were used in this study. The highest seed yield (1163 kg/ha) was obtained by the line 2390, the lowest seed yield was obtained (1110 kg/ha) by the line 2561. As an average, the 1000-seed weight ranged between 171.4 g and 318.8 g, whereas biological yield ranged between 4043 kg/ha and 7899 kg/ha. It has been found that the relationship among the traits varied according to the years. Although there were negative correlations (-0.656**) between 1000-seed weight and seed per pod, and also there was positive correlations (0.830**) between 1000-seed weight and pod length. The biological yield was positively correlated (0.680**) with pod length and 1000- seed weight. Except for the plant height, there was no significant correlation between the seed yield and other characteristics in summer sown lines
