Establishment of the irrigated rice cultivar SCSBRS Tio Taka by recurrent selection.

This study aimed to present and discuss the recurrent selection methodology used in the development of the rice cultivar SCSBRS Tio Taka. This cultivar, derived from the population CNA-IRAT 4, achieves high yields and has agronomic traits related to a better performance in the pre-germinated cultivation system used in Santa Catarina State. The molecular characterization of Tio Taka and CNA-IRAT 4 parents with 16 SSR markers showed that one of the parents, BG 90-2, was highly similar to SCSBRS Tio Taka. The most probable reason was that SCSBRS Tio Taka was extracted from CNA-IRAT 4 in the second recombination cycle, preventing the ccurrence of a high level of recombination and favoring the phenotypic selection of plants derived from crosses with BG 90-2 as parent, once this line has one of the best plant architectures and yields.
