Abstract

The aim of this study was to determine characters that affect seed and hay yield, using simple correlation coefficients and path analysis. The study was conducted in Batı Akdeniz Agricultural Research Institute (BAARI), during 2014-2015 winter growing seasons for two years. The experiments were established in a randomized complete block design with three replications and half of plots for fresh forage and the other half for seeds were harvested. In the study, days to 50% flowering, plant height, fresh yield, hay yield, straw yield, biological yield, harvest index, number of pods per plant, number of seeds per pod, seed yield and 1000-seed weight were observed. According to results of the correlation analysis; a highly significant and positive correlations (P<0.01) were determined between fresh yield, hay yield, biological yield and seed yield. According to the results of the path analysis, the highest direct effect on the hay yield was obtained from fresh yield and straw yield. As a result of the research, to increase the hay yield; straw and fresh yield, and to increase the seed yield; biological yield and harvest index can be suggested as main selection criteria on grass pea breeding studies.
