Multi-trait selection of wheat lines under drought-stress condition

نویسندگان

چکیده

The immediate need for the increase in wheat production to meet future world demand, associated with occurrence of drastic climatic events, such as drought, makes it necessary develop drought-resilient genotypes. aims this work were evaluate use drought-tolerance indices selection genotypes, compare genetic gains grain yield using different strategies by means a multi-trait index, and select superior drought-tolerant total 31 tropical lines was evaluated two experiments. Five agronomic traits accessed. data from stress nonstress experiments used obtain five indices. subjected mixed model analysis, four scenarios designed. There significant effect genotype all traits. inclusion index provided drought condition. Seven selected due high frequency favorable alleles other important Drought-tolerance are appropriate characterizing response genotypes drought-stress. along provides compared non-inclusion

Evaluation of Grain-Quality Related Traits of F5 Lines of Wheat under Terminal Drought Stress Conditions

Extended Abstract Introduction and Objective: Drought stress is the most prevalent and limiting factor in the growth and productivity of crop plants. According to the challenge of deficiency in precipitation or consecutive droughts in recent years in Iran and as a result of a shortage of irrigation water in wheat production, knowledge of the relationship between grain quality and grain yield ...

Catalase and Metallothionein genes expression analysis in wheat cultivars under drought stress condition

Drought stress is one of the serious problems that restricted agronomic plant production worldwide. In molecular level, the harmful effect of drought stress is mostly caused by producing of large amount of reactive oxygen species (ROS). Catalase and Metallothionein genes have a crucial role to mope the hydrogen peroxide (H2O2) resulting reducing oxidative damage. In this research the gene expre...
