Determination of characters associated with seed yield and hay yield by path and correlation analysis in grass pea (Lathyrus sativus L.)

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
