ABSTRACT
Phenotypic correlation coefficients between seed yield and morphological traits of lucerne (Medicago sativa L.) breeding populations were determined. Ranking of populations by seed yield and subsequent calculating of correlations showed that as higher differences in seed yield among populations was as higher correlations were obtained. Among the characters examined seed yield was positively correlated with the length of raceme, number of flowers, pods and seeds per raceme, number of seeds per pod (r=0.31*, 0.61*, 0.42*, 0.57*, 0.53*, respectively). Negative relationships were determined between spring regrowth height, alfalfa mosaic, flowering period, plant regrowth height after harvest, 1000 seed weight and seed yield (r= -0.42*, -0.81**, -0.64*, -0.71*, -0.41*, respectively).
