Superiority index based on target traits reveals the evolution of Brazilian soybean cultivars over last half-century

نویسندگان

چکیده

The objective of this work was to assess the breeding influences in different agronomic and physiological traits Brazilian soybean cultivars, released between 1965 2011, identify associated with modern cultivars. A total 29 cultivars were evaluated two locations 2016/17 crop season. Genotype selection based on determined using GYT (Grain Yield*Trait) methodology, which uses Superiority Index rank genotypes by mean all traits. Grain Yield is combined other target shows strengths weaknesses each genotype. Soybean improved desirable during 46 years evaluation. index can be a powerful tool for breeders obtain high genetic gains future. DMario 58i, TMG 7161RR 7262 RR stand out as best but present sets grain yield, harvest index, number pods per plant, reproductive-vegetative ratio, photosynthetic rate transpiration are core programs.

The genetic base of Brazilian soybean cultivars: evolution over time and breeding implications

Genetic diversity is essential for crop breeding and one way to estimate it is through the concept of genetic base, which can be defined as the number of ancestors and their relative genetic contributions (RGC) to each cultivar. The RGC can be estimated through the coefficient of parentage between the ancestors and cultivars. Previous studies determined that the genetic base of Brazilian soybea...
