Última Estimation of soybean genetic progress in the South of Brazil using multi-environmental yield trials Scientia Agricola Lange,Cláudia Erna; Federizzi,Luiz Carlos. The success of a genetic breeding program in a certain period can be assessed by the genetic gain observed. Genetic progress can be estimated from the multi environmental trials (MET) data which are routinely carried out by annual species breeding programs for the assessment of new commercial cultivars. A data set of 20 years of MET of advanced soybean lines derived from four breeding programs was used to estimate and to compare the genetic gains obtained for three soybean maturity groups (early, medium and late) in four cropping regions of the State of Rio Grande do Sul. The estimated yield gains ranged from 0.0 to 71.5 kg ha-1 year-1 (3.49% per year), depending on the maturity group and region, which suggests that the genetic breeding effort does not...
