Towards a global characterization of winter wheat cultivars behavior in response to stressful environments during grain-filling

چکیده
Starting from grain yield, quality and resistance against multiple diseases, the characterization of cultivar’s behavior increased in recent decades. Needs quantitative assessments a larger range criteria has greatly evolved towards yield stability large fluctuating environments. Using dataset crossing cultivars environments, we thus explored relationships between Healthy Area Duration (HAD), as affected by genotype, environment septoria caused Zygmoseptoria tritici. A set indexes was then proposed to properly profile behavior. curvilinear relationship relating HAD potential first parameterized. It allows quantifying efficiency. Susceptibility (HAD loss) differentiated total tolerance (the ratio loss loss). Finally specific tolerance, i.e. not due level, quantified. Correlations pointed out that no trade-off shown actual or well disease susceptibility. These correlations partially depended on nitrogen status crops, underlining other G×E interactions may trap. Finally, efficiency appeared more highly linked than an alternative based Absorption (HAA) accounted for meteorological variability. Interestingly, these last were insensitive nutrition cultivar susceptibility Z. The developed allowed profiling cultivars’ under common HAA-based open way useful global breeders. Moreover, HAA can be assessed using high-throughput phenotyping tools. thorough evaluation this point needs done.

The interaction of hormones plays an important role in plant equilibrium, especially, when plants encountered to environmental stresses, during both vegetative and generative stages. For this purposes, the experiment was designed based on the interaction effect of exogenous treatments of individual kinetin (Kin) and 24-epibrassinolide (24-EBL) and their dual application with two level of field ...

Vernalisation Response of Some Winter Wheat Cultivars (Triticum aestivum L.)
For 17 cultivars of winter wheat (Triticum aestivum L.) different vernalisation and photoperiod responses were detected. The effect of photoperiod sensitivity was not significantly changed by vernalisation; different vernalisation responses were probably due to the presence of multiple alleles at Vrn loci. The delay in heading depended on the vernalisation deficit exponentially: y = parameter (...
