Descripción: | 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. |
