Abstract

The major abiotic factor limiting crop growth is the availability of water.  Yield is the main indication of selection under moisture stress conditions. Selection efficiency can be improved identifying morphological and / or physiological attributes related to performance under stress environments as additional selection criteria. These characteristics should be positively related to stress tolerance and be easily evaluated. The study was conducted in two localities in northern Mexico dur ing the fall-winter 2012-2013 in Zaragoza, Coahuila, and the summsummer of3 in Navidad, N.L., where 33 triticale genotypes under different moisture regimes were evaluated. A complete randomized design with three replications in five environments of moisture was used. Individual and combined analysis of variance between environments were performed. The variables were: peduncle length (PL), spike length (SL), pe duncle dry weight (PDW), spikes dry weight (SDW), flag leaf dry weight (FLDW) and grain yield (GY). Highly significant differences between environments, treatments, and treatment x environment interaction were recorded. The mean test between environments showed that environments with lower water stress reported higher values for all traits.  Regression analysis between morphological and agronomic variables and grain yield showed a significant and positive relationship. Indirect selection for drought tolerance in triticale is feasible, particularly pe duncle length, which is of easy evaluation, becoming useful tools in the selection of genotypes in environments with moisture deficits.
