Evaluación de variedades de caña de azúcar (Saccharum spp.) introducidas al estado de Quintana Roo, México

Objective: Find at least one variety of (Saccharum spp.) that exceeds, or at least equals, the local varieties in terms of cane yield in the field and factory sugar. Design/methodology/approach: Ten varieties of sugarcane introduced to the state of Quintana Roo during the template cycle were evaluated, which were compared with two local varieties, NCo310 and CP722086. The experimental design consisted of randomized complete blocks and arrangement of divided plots with three repetitions. , in which the treatments were varieties. Measured variables were the length of the stalk (LTM), stem diameter (DT), number of stems per strain (NTM), sucrose content (SAC), field cane yield (RCC) and sugar yield (RA).  Results: The results obtained indicated that at least three varieties of sugarcane introduced had higher agronomic performance and yield than the varieties of the region (control). Regarding the RCC, the varieties B86326, LAICA96606 and CYZ82154 had 162, 147 and 143 t ha-1, respectively, compared with 123 and 136 t ha-1 of the control varieties NCo310 and CP722086, respectively; in terms of sugar yield, the varieties CP941674, SP835073 and SP811763 stand out, with 15.26, 14.46 and 14.09 t ha-1, compared with the control varieties, 15.39 and 12.28 t ha-1 for CP722086 and NCo310, respectively. Limitations on study/implications: An important limitation for this study is that there was only one culture cycle for the evaluation. Also, the irrigation conditions were not counted. Findings/conclusions: Varieties with outstanding yields field (RCC) and sugar (RA) were: CP941674, SP835073, SP811763 and LAICA9213, so its reproduction and culture is recommended.
