Yield potentials of narbonne vetch (Vicia narbonensis L.) genotypes in different environmental conditions

Abstract

The purpose of the research was to determine the yield potentials of narbonne vetch (Vicia narbonnesis L.) genotypes in different environmental conditions. Narbonne vetch genotypes were grown in three different locations of Trakya region during 2002-2004. Eight Narbonne vetch genotypes (genotype numbered 236, 512, 524, 570, 908, 14, Ege and one population) were used as material in the research. The results showed that seed yield, herbage yield and hay yield were significantly affected (P <= 0.05) by genotypes, while branch number and pod number per plant were not significantly affected by genotypes. Therefore, plant height and thousand seed weight were significantly affected (P <= 0.01) by genotypes. Plant height, seed yield, herbage yield and hay yield were significantly affected (P <= 0.01) by locations and location x genotype interaction. Branch number per plant, pod number per plant and thousand seed weight were not affected significantly by locations. While the highest seed and forage yields were obtained in Hayrabolu location, seed and forage yields in Kirklareli were less than in the other locations. In the study; plant height, branch number, pod number, thousand seed weight, seed yield, herbage yield and hay yield were 43.02 - 78.85 cm, 1.40 - 3.17, 6.63 - 19.23, 173.83 - 239.09 g, 143.48 - 351.24 kg da(-1), 821.31 - 2710.79 kg da(-1) and 134.63 - 482.16 kg da(-1), respectively. It was concluded that genotype numbered 908 in Hayrabolu, genotype numbered 512 in Tekirdag and genotype numbered 524 in Kirklareli were suitable for forage production whereas genotype numbered 908 in Hayrabolu, genotype numbered 908 and 570 in Tekirdag and genotype numbered 512 in Kirklareli for seed production. Narbonne vetch genotypes had different yield potentials in three environmental conditions of Trakya region which is in the Marmara region of Turkey.
