Progress, adaptability and stability of soybean grain yield and grain quality in conventionally created elite lines

The objective of this study was to determine the progress in grain yield and quality accomplished with conventional breeding methods, as well identify stable, widely or specifically adapted genotypes under central European growing conditions. Recently developed soybean elite lines maturity groups (MGs) 00, 0 I were compared commercial cultivars (standards) comparative field tests during three consecutive years (2018-2020) Osijek, Croatia. ANOVA results showed significant genotype, environment, genotype-by-environment interaction effects. There a improvement productivity comparison standards, while stability parameters for tested traits indicated there are stable mostly adaptable lines. Improvement domestic gene pool high agronomic performances most important economic will considerably contribute increasing improving production Europe.
