BARRIOS GOMEZ, Edwin Javier et al. INIFLAR RT, variety of rice grain thin for Mexico. Rev. Mex. Cienc. Agríc [online]. 2016, vol.7, n.4, pp.969-976. ISSN 2007-0934.

The rice variety INIFLAR RT was introduced to Mexico in 2005 as a line in F6 generation, through international nurseries observation Latin American fund irrigated rice (VIOFLAR-2005). This genotype is derived from the triple cross between CT10825-1-2-1-3/FEDEARROZ50// FLO2066-4P1-1P-M progenitors was obtained which progeny encoded by FLAR as FLO4621 (F1), in Palmyra, Colombia. The F1 seed (masal harvest) were seeded to generate F2 in which a harvest was performed using the pedigree method (selection of individual plants). Genealogical four more selections were made, until the F5, to form latter selection masal, was called FLO4621- 2P-1-3P-3P-M. Once introduced to Mexico, the F5 was evaluated in two cycles: 2006 and 2009 with preliminary performance tests in the dry tropics, then two trials were conducted in 2011 and 2012 in the dry and humid tropics. In 2013 the evaluation was conducted in a compact performance test (ECR), the genotype x environment interaction was determined, and a study of stability parameters under different environments of the humid tropics and dry tropics. During 2014 the validation was performed nationally and temporary irrigation in dry and humid tropics; also it confirmed the laboratory milling quality rice Campo Experimental Zacatepec, Morelos and produced basic seed. Six years of evaluation were performed before starting the registration of the new variety, which earned an average yield of 7.1 t ha-1 in 2013 and 2014, a ton above the national witness The Silverio, later variety. The number of provisional registration with the SNICS is the 3103-3103-ARZ-017-230315/C.
