“…One of the main factors that contributed to the increase in rice production was the use of improved and adapted cultivars to irrigated and rainfed crops; this is because the generated cultivar seeds are of low cost and easy adoption by farmers in Brazil (Rangel et al, 2000; Soares et al, 2017). Considering the increasing demand for this cereal, breeding programmes focused mainly on the development of higher yielding cultivars (de Oliveira et al, 2020).…”

Rice is one of the most consumed cereals in the world and of extreme social and economic importance in Brazil. Minas Gerais is the leading State in irrigated rice production in the Southeast Region. This study aimed to estimate the genetic progress of 26 years of the irrigated rice breeding programme of Epamig in Southeast Brazil by time meta‐analysis. Genetic progress was estimated for grain yield, plant height and days to flowering. The dataset understood 162 genotypes in 91 trials of value for cultivation and use of 26 seasons. The rate of annual genetic gain for grain yield was estimated .99% (49.85 kg year−1). It was also verified that was a reduction in plant height and an increase in days to flowering, even if very low. Due to distinct historical phases of the rice breeding programme, there were changes in research focus and, consequently, affected the genetic gains. With this study, it was possible to evaluate the selection strategies carried out in the past and identify important points to maintain.

“…One of the main factors contributing to improve the rice production was the planting of improved cultivars, adapted to each cultivation modality. The reason is that the developed technology (in the form of new cultivars) is cheap and easily implemented by farmers, providing significant gains in crop yields (Soares et al 2017).…”
