Identification of Drought Tolerant Oilseed Rape Genotypes using Multivariate Analysis
Extended Abstract Introduction and Objective: Drought stress as one of the most important abiotic stress is the main limiting factor of oilseed rape cultivation in arid and semi-arid climates. Therefore, the identification of drought tolerant genotypes is the essential programs in these regions. One of the appropriate methods to identify drought tolerant genotypes is the use of stress toleranc...
متن کاملIdentification of Drought Tolerant and Sensitive Species of Thyme through Some Physiological Criteria
Drought as the most important abiotic stress has deleterious effects on plants. Developing drought tolerant varieties can help produce plants in a sustainable way. This study was conducted to identify drought tolerant and drought sensitive thyme species including Thymus vulgaris, T. vulgaris (origin: Spain), T. carmanicus, T. daenensis and T. kotschyanus and to study the mechanism used by them ...
متن کاملDescription of future drought indices in Virginia
This article presents projected future drought occurrences in five river basins in Virginia. The Soil and Water Assessment Tool (SWAT) and the Coupled Model Intercomparison Project Phase 5 (CMIP5) climate models were used to derive input variables of multiple drought indices, such as the Standardized Soil Moisture index (SSI), the Multivariate Standardized Drought Index (MSDI), and the Modified...
متن کاملHigh Antioxidant Activity Facilitates Maintenance of Cell Division in Leaves of Drought Tolerant Maize Hybrids
We studied the impact of drought on growth regulation in leaves of 13 maize varieties with different drought sensitivity and geographic origins (Western Europe, Egypt, South Africa) and the inbred line B73. Combining kinematic analysis of the maize leaf growth zone with biochemical measurements at a high spatial resolution allowed us to examine the correlation between the regulation of the cell...
متن کاملDrought-Tolerant Corn Hybrids Yield More in Drought-Stressed Environments with No Penalty in Non-stressed Environments
The potential benefit of drought-tolerant (DT) corn (Zea mays L.) hybrids may depend on drought intensity, duration, crop growth stage (timing), and the array of drought tolerance mechanisms present in selected hybrids. We hypothesized that corn hybrids containing DT traits would produce more consistent yields compared to non-DT hybrids in the presence of drought stress. The objective of this s...
متن کاملIdentification of Drought Tolerant Lines from Interspecific Hybridization in Two Different Genetic Backgrounds of Barley under Different Irrigation Regimes
Domestication and artificial selection have reduced the level of genetic variation in barley. Inter-specific hybridization is one of the most valuable ways to restore at least part of the lost variation. This study aimed to investigate genetic diversity and screening barley lines which possessed the desired traits, as well as drought tolerance, within two F3 populations derived by crossing a cu...
