In this study was used 9 soybean varieties improved in Turkey and 3 soybean varieties (Blaze,
Nova, Progen 375 as control group) in foreign origin. The experimental areas were conducted
with randomized block design and three replications, two locations in Black Sea Region located
in northern Turkey. New varieties were improved by Research institues and Universities of
Turkey (Nazlıcan, Türksoy,Adasoy, Ustun1, Atakisi, Arısoy, Ataem-7, Erensoy, Umut 2002and
represented 3 rd , 4 th and 5 th maturity groups. Plant height ranged from 112.8 cm to 195.9 cm, first
pod height 8.5-21.0 cm, pod number per plant 91.7-189.2, seeds per pod 2-3, branches per plant
1.0-5.43, seed yield per decare 335.5-570.7 kg, biological yield per plant 90-175 g, seed yield per
plant 37.4-102.5 g, harvest index 28.0-40.8 % and 1000-kernal weight 125.0-235.0g. Protein and
oil contents varied between 39.6-43.1 % and 16.1-18.5 %, respectively. Furthermore, positive
relationships were determined between pod number per plant and biological yield (r= 0.835**),
between pod number per plant and seed yield per plant (r= 0.637*) and between seed yield
(kg/da) and harvest index (r= 0.581*). Improved varieties Erensoy and Atakisi gave higher seed
yield from foreign varieties in Terme location and improved varieties Ustun1, Turksoy, Ataem 7
and Atakisi in Bafra location. However, it was concluded that this research is still continuing in
different locations in order to determine the effects of the climate and other enviromental factors
on yields and qualities of soybean varieties improved in Turkey.
