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 plant height of narbon vetch were in vestigated using path analysis in Bingol in 2014-15 years. The plant measures of narbon vetch between 4 and 6 weeks of planting were used. The results showed that the highest correlations at 5 week narbon vetch were 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 leafweight, dry leafweight on plant length at 6 week narbon vetcies were determined respectively as 51.341\%, 50.148\%, 37.782\%, and 24.276\%, respectively. As a result, fresh stem weight, dry stem weight were the most efficient characters on plant length and it was concluded that these characters could be considered as significant selection criterias in narbon vetch breeding for yield under that the conditions.
