Analysis of some plant measures of narbon vetch (Vicia narbonensis L.) effecting plant length using path analysis

Abstract

The direct and indirect effects of sizes of fresh stem weight, dry stem weight, fresh leafweight, dry leaf weighton plantheight of narbon vetch were in vestigated using path analysis in Bingol in 2014-15 years. The plant measures of narbonvetch between 4 and 6 weeks of planting were used.The results showed that the highest correlations at 5 week narbon vetchwere determined between plant length and respectively dry stem weightand fresh stem weight(r =0.849 and r =0.824). The direct effects of fresh stem weight, dry stem weight, fresh leaf weight, dry leaf weight on plant length at 6 week narbonvetcies were determined respectively as 51.341%, 50.148%, 37.782%, and 24.276%, respectively. As a result, fresh stemweight, dry stem weight were the most efficient characters on plant length and it was concluded that these characters couldbe considered as significant selection criterias in narbon vetch breeding for yield under that the conditions.
