This research was carried out Yuzuncu Yil University, Agricultural Faculty experimental field in 2002-03 and 2003-04. The experiment was conducted to determine the relationship among yield and some yield components using correlation and path coefficient analysis. In the experiment 12 pea genotypes were used. The experiment was designed randomized complete blocks design with four replications. At the end of the study, positive and significant relationship were found among seed yield and pods per plant and biological yield in both years. The strongest and direct positive effects were the biological yield (p = 0.6500), numbers of pods per plant (p = 0.3137) and the seed yield. These were followed by first pod height (p = 0.2398) and number of seeds per pod (p = 0.2227).

Key words: Pea, path coefficient, correlation, yield, yield components.
