BARRIOS GOMEZ, Edwin Javier; GONZALEZ GABRIEL, Franccede; CANUL KU, Jaime  e  HERNANDEZ ARENAS, Marianguadalupe. Evaluation of advanced lines of rice, coarse-grained in Morelos, Mexico. Rev. Mex. Cienc. Agríc [online]. 2016, vol.7, n.5, pp.1091-1102. ISSN 2007-0934.

The aim of this study was to evaluate the effect of the transplant date and environment on the agronomic performance of five advanced lines of rice (Oryza sativa L.) type Morelos. The first date of transplant took place on april 11 and the second on 12 may 2014. It were evaluated in five locations: Jojutla, Cuautla, Mazatepec, E. Zapata and Cocoyoc, in the state of Morelos. Five lines were studied: C7Za05, C14Za06, C20Za06, C21Za06, C27Za06 and witness the variety Morelos A-2010. The experimental design was a randomized complete block in factorial arrangement, where the sources of variation were: date of transplant, locations and genotypes (lines); for statistical data analysis see was used the SAS program. 9.0. During harvest, the variables recorded were: plant height, productive and unproductive tillers, panicle length, grains per panicle, stained grains per panicle vain grains and grain weight in one square meter. The transplant date showed significant differences for almost all variables; the environment, genotype and interaction between the two factors showed highly significant differences. For grain weight, the best atmosphere was Jojutla and outstanding materials were Morelos A-2010 and C21Za06 line, which obtained a yield of 1.22 kg m-2, the combination of Jojutla environment with C20Za06 line had the highest performance 1.4 kg m-2.
