Summary: This study evaluated 25 barley varieties under normal and drought stress conditions to identify tolerant varieties and determine the influential yield components. The cluster analysis grouped genotypes into different clusters under both conditions, showing the limiting effect of drought on phenotypic variability. Certain traits, such as spike weight, leaf area, and grain number per spike, were found to have the most impact on grain yield under normal conditions, while other traits like number of fertile spikelets and grain number per spike were influential under water deficit conditions. Additionally, stress tolerance index (STI), harmonic mean productivity (HMP), and mean productivity (MP) were identified as proper indices for screening tolerant barley genotypes.

Summary: Melatonin enhances drought tolerance in cotton plants by modulating the antioxidant system, increasing photosynthetic activity, water-use efficiency, and nitrogen metabolism. The study also found that the effect of melatonin differs between drought-sensitive and drought-tolerant varieties, with more pronounced effects observed in the sensitive variety. Additionally, the study suggests that autophagy may play a role in alleviating drought stress.

Summary: By identifying salt-tolerant and drought-tolerant varieties of rice, constructing variation maps, and screening candidate genes, multiple important stress tolerance genes for salt and drought resistance were discovered. These findings contribute to understanding the genetic variations among elite stress-tolerant varieties and provide a foundation for further comprehensive investigation of the genetic basis of salt and drought tolerance.

Summary: The study in Kenya found that scalability of drought tolerant maize varieties (DTMVs) can be increased by addressing constraints related to farmer knowledge, seed access, and seed affordability, potentially doubling adoption rates from 26% to 52% and even higher. Public-private partnerships are necessary to ensure sustained supply of seed at competitive prices.

Summary: The study found a strong positive correlation between the adoption of drought-tolerant maize varieties and maize yield, increasing the area planted with DT varieties can significantly increase maize yield and help reduce production losses due to drought. Policies promoting increased allocation to DT varieties hold the potential to enhance food security, while further efforts are needed to breed DT varieties that are adaptable to various climatic conditions.

Summary: Drought-tolerant maize varieties offer hope for farmers in sub-Saharan Africa facing droughts. Adoption of these varieties could generate significant economic benefits in Tanzania, potentially lifting 1.6 million people out of poverty by 2032. The largest benefits would occur in major maize-producing regions. These findings justify investments to support the scaling of these varieties in Tanzania.

Summary: This study examines the factors influencing the adoption intensity and welfare impacts of drought-tolerant rice varieties in Bangladesh. It finds that training and technology-related factors play a significant role in boosting adoption intensity. Full adopters of drought-tolerant varieties have higher yields and income compared to non-adopters, and can consume more rice from their own production.

Summary: Pearl millet is a C-4 crop grown in the tropics and subtropics of the Indian subcontinent and sub-Saharan Africa for its grain and stover. The increasing intensity of drought due to climate change necessitates a greater focus on breeding for drought tolerance in pearl millet. Advances in genomics and molecular biology have provided tools to enhance the development and delivery of high-yielding and drought-tolerant cultivars.

Summary: Heat stress has a significant negative impact on maize growth and yield attributes, reducing key factors such as leaf chlorophyll content, leaf area, plant height, stem diameter, dry biomass yield, and harvest index. Sandy clay loam soil is more conducive for maize growth compared to loamy sand soil. Organic manure soil amendment can improve maize growth attributes and mitigate the effects of heat stress, making it an important consideration for food security in sub-Saharan Africa.

Summary: Rice, an important food crop, is severely affected by drought stress. Under drought conditions, various morphological, physiological, and molecular changes occur in rice, leading to reduced growth and yield. Improving rice drought tolerance through molecular tools and techniques is discussed.

Summary: This study aimed to investigate the variability for drought tolerance among potato cultivars. By conducting experiments over 11 years, the stability of drought tolerance of potato cultivars under different water regime conditions was examined. Data on the responses of 50 potato cultivars to drought stress were collected, and tuber yield and other parameters were analyzed. Through the evaluation of ensemble learning models, a classifier with 96.7% accuracy was developed to distinguish different tolerance groups.

Summary: Drought is a costly and deadly natural hazard. While regional scale drought propagation has been well studied, quantifying global scale drought propagation and variability is still challenging. This study maps the spatial and temporal propagation of drought through different subsystems at a global scale, providing valuable insights into its impacts.
