Abstract :In this study, six pea cultivars (Karina, Kosmos, Sprinter, Jofs, Manuel and Bolero) were sown in 3 different sowing dates in 15 April, 23 April, 3 May (1998) and 15 April, 22 April, 5 May (1999) for a consecutive years to determine the relations between the seed yield and some morphological characteristics of different cultivars. Experimental design was a Split Plot of randomized blocks in 3 replications. The experiment was established in the experimental site of Konya Rural Affairs Research Station. There have been significant differences between the sowing dates, years and cultivars with respect to seed yield. Based on average of years and cultivars, the highest seed yield (168.9 kg/da) was obtained when sown in the first sowing date. Correlation analyses of mean values of cultivars revealed significant positive interactions between seed yield and first pod height (0.222**), plant height (0.240**), pod length (0.203**) and number of seed per pod (0.202**). Regression analyses based on mean values of two years and mean values of each year separately have shown that seed yield was affected by morphological characteristics by 76.5 % in the first year, by 78.7 % in the second year and by 51.7 %.
