SAKIYAMA, Ney Sussumu; RAMOS, Helaine Christine Cancela; CAIXETA, Eveline Teixeira  e  PEREIRA, Messias Gonzaga. Plant breeding with marker-assisted selection in Brazil. Crop Breed. Appl. Biotechnol. [online]. 2014, vol.14, n.1, pp.54-60. ISSN 1984-7033.  https://doi.org/10.1590/S1984-70332014000100009.

Over the past three decades, molecular marker studies reached extraordinary advances, especially for sequencing and bioinformatics techniques. Marker-assisted selection became part of the breeding program routines of important seed companies, in order to accelerate and optimize the cultivar developing processes. Private seed companies increasingly use marker-assisted selection, especially for the species of great importance to the seed market, e.g. corn, soybean, cotton, and sunflower. In the Brazilian public institutions few breeding programs use it efficiently. The possible reasons are: lack of know-how, lack of appropriate laboratories, few validated markers, high cost, and lack of urgency in obtaining cultivars. In this article we analyze the use and the constraints of marker-assisted selection in plant breeding programs of Brazilian public institutes.

Palavras-chave : Molecular markers; indirect selection; MAS.
