BARRIOS GOMEZ, Edwin Javier et al. Morelos A-2016: variety of coarse-grained rice. Rev. Mex. Cienc. Agríc [online]. 2018, vol.9, n.7, pp.1547-1552.  Epub Sep 30, 2020. ISSN 2007-0934.  https://doi.org/10.29312/remexca.v9i7.680.

In the central zone of Mexico, rice (Oryza sativa L.) is planted under transplant and in direct sowing under irrigation; most varieties have been released for transplant. In 2005, one of these lines was used as a parent and continued with the generational advance to F5. In 2011, a preliminary performance test was carried out on several groups of lines, around 256 materials, from which C14Za06 was identified as outstanding (currently, Var. Morelos A-2016). In 2014 and 2015 different lines were evaluated in performance trials in the towns of Zacatepec, Jojutla, Emiliano Zapata, Mazatepec, Coatlan del Río and Cuautla, Morelos state; in addition to the commercial witness Morelos A-2010. Of the evaluated materials, C14Za06 stood out for its yield superior to 10 t ha-1, moderate resistance to pyricularia, high tolerance to grain staining, semi-erect growth habit, plant height of 130 cm, resistant to lodging; industry performance of 57% whole polished grain; conserving the Morelos quality (20% of white center).

Keywords : Oriza sativa L.; irrigated rice; Morelos quality; tolerance to diseases.
