Caracterización agronómica de cinco accesiones de triticale (Xtriticosecale), en el tercer año de evaluación en Laguacoto, provincia Bolívar

The cultivation of Triticale represents a good alternative due to its high biomass production, grain yield and for the production of animal feed. In addition, it has great characteristics of its parents, such as greater resistance to foliar diseases and has great adaptability to both different soils and climates. This research focused on the agronomic characterization of five Triticale accessions from INIAP, evaluated during the third consecutive year in the Laguacoto locality, Bolívar province. The objective was to characterize these accessions agronomically and select the best accession based on its agronomic and sanitary response. A Randomized Complete Block Design (DBCA) was used, with three repetitions. Agronomic characteristics such as PCP, PMG, PH and R were evaluated. In addition, an analysis of variance, Tukey test, classification and linear regression were performed. The results did not reveal significant differences between the accessions. The five accessions presented resistance to foliar diseases such as; yellow rust (Puccinia striiformis), Fusarium and Yellow dwarf virus (BYVD). Grain yield varied between 5330.3 and 6693.1 Kg/ha, treatment T4 (TCL-10-004) obtained greater efficiency. Based on its agronomic and health response, access T4 (TCL-10-004) is considered the most promising, being the treatment that presents the highest values due to its superiority in terms of yield, morphological descriptors and low level of viruses. However, treatments T3 (TCL-10-001) and T5 (TCL-11-006) are notable options for their zero incidence of viruses. This study provides valuable information for the optimization of Triticale cultivation, emphasizing the need to select accessions with high productivity and disease resistance, which is essential for the improvement and sustainability of agricultural production.
