Investigation of yield and yield components in main crop soybean genotypes in Adana conditions

The research was carried out in Adana conditions to determine the relati-onships between seed yield and yield components of some soybean ge-notypes depending on the years. In this research, which was carried out in 2015 and 2016 years, it was established with 5 soybean varieties and one variety candidate and according to Randomized Complete Block De-sign with 4 replications. In the combined analysis of variance, the year*genotype interaction was insignificant in terms of yield and yield components, while other sources of variation (year and genotype) were found to be statistically significant compared to P <0.01. Seed yield showed changed between 5782-6788 kg ha-1 in 2015 and 3597-4359 kg ha-1 in 2016. In the correlation between the examined traits; While there was a significant and positive relationship between seed yield and day to flowering, days to maturity, first pod height and oil rate, there was a significant and negative relationship between 1000 seed weight and the number of pods per plant. The varyans analysis showed that the inter-actions of year, genotype and year*genotype were significant in terms of seed yield and yield components of genotypes. As a result, Cinsoy, variety candidate 1 (Mona) and Blaze of varieties showed high performance in Adana conditions, and it was determined that the effect of the environment was higher than the effect of genotype and interaction in terms of seed yield and other traits. As a result of this study, the variety candidate 1 was registered under the name Mona. In addition, it was concluded that Cinsoy, Blaze and newly registered Mona varieties can be recommended for main crop soybean cultivation in Adana conditions.
