Abstract: 

In order to study relative water content (RWC) and canopy temperature depression (CTD) under different water limited conditions in hexaploid triticale genotypes, the present investigation was carried out during growing seasons of 2001-2003, at Turogh field station, Khorasan Agric. Res. Center. This experiment was laid out in split plots design using RCBD. Main plots (L) were water limitations in different growth stages with 6 levels (L1, optimum conditions, L2, L3, L4 water limitation in vegetative pre anthesis, reproductive pre anthesis and post anthesis stages respectively, L5 and L6 received rainfall during cropping seasons with only one supplementary irrigation at anthesis and grain filling period respectively). Five hexaploid triticale genotypes (Jjuanillo 92 and four promising lines) were considered as sub plots. Results revealed that there was a reduction in RWC and CTD with development of phenological stages under optimum conditions, while no distinct trend was observed in water stress treatments. Imposing water stress during vegetative pre- anthesis phase. (L2) could significantly decline RWC and CTD only at flag leaf stage. However, reduction of RWC and CTD was not significant during anthesis and grain filling due to plant recovery during these stages. Minimum RWC and CTD were recorded during flag leaf and anthesis in L3 (water stress from double ridge to anthesis). Irrigation following water stress could not compensate RWC and CTD reduction even during grain filling period. Although these two indices were higher in L3 than post anthesis water stress (L4). Significantly positive correlations between yield, CTD and RWC were observed during all developmental stages. However, these correlations were higher in grain filling period. It was found that CTD is more reliable selection index for grain yield as compared to RWC. Result showed that there is a variation among genotypes concerning CTD and RWC in different development stages. Genotypes with higher yield under water stress expressed better CTD and RWC performance at different stages.
