Selection indices to identify drought-tolerant grain sorghum cultivars.
Twenty-five cultivars of grain sorghum [Sorghum bicolor (L.) Moench] were examined under both drought stress and normal conditions in 4 experiments. In each condition, genotypes were evaluated in a factorial experiment using a randomized complete block design with 3 replications. Eight drought tolerance indices including stability tolerance index, mean productivity (MP), geometric MP, harmonic ...
متن کاملTranscriptomic Changes of Drought-Tolerant and Sensitive Banana Cultivars Exposed to Drought Stress
In banana, drought responsive gene expression profiles of drought-tolerant and sensitive genotypes remain largely unexplored. In this research, the transcriptome of drought-tolerant banana cultivar (Saba, ABB genome) and sensitive cultivar (Grand Naine, AAA genome) was monitored using mRNA-Seq under control and drought stress condition. A total of 162.36 million reads from tolerant and 126.58 m...
متن کاملMolecular Markers for New Promising Drought Tolerant Lines of Rice under Drought Stress via RAPD-PCR and ISSR Markers
Random amplified polymorphic DNA polymerase chain reaction (RAPD-PCR) and inter simple sequence repeats (ISSRs) markers were performed to detect the genetic diversity among 6 new rice lines and 4 cultivars with different responses to drought tolerance and establish specific DNA markers associated with drought tolerance. Among 16 RAPD primers tested, only 5 produced bands polymorphic between lin...
متن کاملIdentification 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 کاملDrought-Stress Induced Changes in the Expression of Acid Phosphatases in Drought Tolerant and Susceptible Cultivars of Wheat
The variability in acid phosphatase activities was studied with an objective to find out its physiological role in response to drought stress. The effect of drought stress on acid P-ase activity in relationship with phosphorus was studied in drought tolerant (C-306) and drought sensitive (HD-2004) cultivars of wheat. Drought stress was imposed by withholding water irrigation to the growing seed...
