Oxidant related biochemical traits are significant indices in triticale grain yield under drought stress condition

Abstract

Two separate experiments, one as drought stress condition and the other one as the normal irrigation condition based on randomized complete block design (RCBD) with three replications were implemented to examine 20 triticale (Triticoseclae wittamack X) genotypes of which 19 genotypes have recently been generated by crossing different parent lines and the other one was Javaniloo, common cultivar. Based on the results of different statistical techniques and comparing relationships among traits for normal irrigation and stress condition, enzymatic antioxidant could be used as criteria for screening tolerant genotypes of triticale. On the other hand, it is pointed out that superoxide dismutase (SOD) are the most important criteria to achieving higher tolerant genotypes through indirect selection. Furthermore, hydrogen peroxide (H2O2) and malondialdehyde (MDA) content with having highly relationship with rain yield are also different possible criteria for screening triticale genotypes for water stress conditions in which genotypes with lower content of these traits could be screened.

Superoxide dismutase (SOD) as a selection criterion for triticale grain yield under drought stress: a comprehensive study on genomics and expression profiling, bioinformatics, heritability, and phenotypic variability

“…In accordance with our results regarding the importance of SOD activity, the relationship of biochemical features and grain yield of triticale was modeled in the study of Saed-Moucheshi [ 45 ], without estimation of their heritability and other genotypic parameters, and it showed that showed that MDH, proline contents and SOD were the important features with significant impacts on triticale grin yield. Similarly, Riasat et al [ 43 ] nominated SOD activity as the most appropriate trait to obtain higher tolerant triticale genotypes. In addition, there are several studies on different crops that are in concordance with our results regarding the importance of biochemical features as the selection criteria [ 1 , 33 , 44 , 54 , 58 ].…”

Participation of Wheat and Rye Genome in Drought Induced Senescence in Winter Triticale (X Triticosecale Wittm.)

“…Qualitative traits related to plant senescence have already been mapped for e.g., sorghum, maize, rice, wheat, potato, or cowpea [38][39][40][41][42][43]. Drought-induced plant senescence markedly limits crop productivity [44]. This is the first study that presents the results of QTL mapping in triticale, where drought-induced senescence may be controlled by wheat or/and rye genome [27].…”

Superoxide Dismutase (SOD): From Genomics and Expression Profiling to Heritability and Phenotypic Variability in Triticale Under Drought Stress

“…In accordance with our results regarding the importance of SOD activity, the relationship of biochemical features and grain yield of triticale was modeled in the study of Saed-Moucheshi (2018), without estimation of their heritability and other genotypic parameters, and it showed that showed that MDH, proline contents and SOD were important features with significant impacts on triticale grin yield. Similarly, Riasat et al (2019) nominated SOD activity as the most appropriate trait to obtain high tolerant triticale genotypes. In addition, there are several studies on different crops that are in concordance with our results regarding the importance of biochemical features as the selection criteria (Riasat et al, 2020;Tabarzad et al, 2017;Vosough et al, 2019;Zahedi et al, 2016).…”
