This study was conducted to determine effect of cultivar, inoculation, and sowing date and to yield and yield components of the only cultivated local genotype in comparison to new sweet cultivars in the 2006-2008 vegetation period in Turkey (41 degrees 21' N, 36 degrees 15' E). Six varieties ('Bardo', 'Fortuna', 'Boruta', 'Borlana', 'Arabella', and 'Sonet') were obtained from Germany, and three varieties were ('Amigo', 'Lolita', and a local genotype) obtained from Turkey. In these experiments, seed yield, thousand seed weight, plant height, first pod height, number of pods per plant, pod length, number of seeds per pod were investigated. In terms of these investigated features it was determined that there were differences among varieties. The local genotype in regards to seed yield performed better than the introduced sweet cultivars in each year and each treatment. However, annual environmental conditions that changed with the years, inoculation, sowing date, and genotypic (cultivars) differences may affect yield and some of the yield components. Seed yield from the autumn sowing were higher than spring sowing in both years (1.72, 2.49 t ha(-1) in autumn sowing, 1.37, 1.69 t ha(-1) in spring sowing, respectively), and inoculation of seed also increased seed yield.
