Summary: Drought tolerance in 138 elite sugarcane hybrids was determined using the membership function value of drought tolerance. Five traits were found to be closely related to drought resistance and could be used as indicators for screening drought-resistant cultivars. Ten sugarcane hybrids were identified as highly drought-resistant, while 14 genotypes were highly susceptible to drought, providing ideal materials for studying the mechanisms of drought sensitivity in sugarcane.

Summary: This study investigates the adaptability of 10 common bean genotypes of indeterminate growth type under water scarcity conditions by measuring agronomic and physiological parameters. The results show that certain genotypes exhibit better adaptability when water scarcity occurs at an early or later stage.

Summary: By testing 20 winter wheat cultivars for drought stress tolerance, our study found that genotypes originating in Western Europe and the warmer regions of southeastern Europe displayed the highest response to experimental drought in different measurements. This suggests the potential for selecting genotypes with increased drought resistance within existing cultivars.

Summary: Water deficits are a major constraint in some potato-growing areas, especially at the tuberization stage, resulting in lower yield. A study in Colombia showed that genetic and phenotypic variations in response to water deficits can accelerate breeding efforts. The research also revealed that physiological, biochemical, and yield-component variables have broad variation, with tuber yield being more strongly correlated with drought tolerance in potato genotypes.

Summary: Stumpy irrigation water availability is crucial for sugarcane production in Pakistan, but it is hindered by inadequate water distribution and uneven rainfall. The study evaluated sugarcane clones' performance under low water availability in sandy loam soil and identified genotypes with resistance and susceptibility to water deficit. Genotypes S2006-US-658, S2007-AUS-384, and HSF-240 exhibited better physiological traits under water deficit, while CP 77-400, S2008-FD-19, S2006-US-469, and S2003-US-633 showed reduced growth and development under stressed conditions. The study emphasizes that sugarcane can sustain its growth with less irrigation frequency or moisture availability, with certain variations.

Summary: In this study, a transcription factor from Tripidium arundinaceum was introduced into a commercial sugarcane cultivar, resulting in enhanced drought tolerance without compromising growth and major quality traits. This research is of great importance in improving sugarcane's drought resistance and reducing yield losses.

Summary: Applying exogenous zearalenone (ZEN) can effectively alleviate water deficiency stress in pea and yellow lupine, increasing crop yield and quality. ZEN reduces the effects of drought stress by stabilizing cell membranes and enhancing antioxidant enzyme activity, while also modifying seed composition without accumulation of exogenous ZEN.

Summary: The study found that traits such as seed cotton yield and number of bolls are significantly affected under water-deficit conditions, with certain varieties showing better tolerance. There is a positive correlation between seed cotton yield and proline contents and chlorophyll fluorescence, suggesting these traits can be used to select cotton genotypes with better adaptation to water-deficit conditions.

Summary: This study aimed to investigate the effects of early drought stress on physiological parameters and agronomic traits of sugarcane genotypes. The results showed that early drought stress decreased certain photosynthetic parameters and significantly reduced cane yield, with the genotype KK3 exhibiting higher productivity under drought conditions.

Summary: This study comprehensively analyzed the biochemical and transcriptomic profiles of two Dendrobium officinale genotypes under three drought stress conditions. The results showed that the M genotype exhibited weaker drought tolerance, with withered leaves, increased malondialdehyde accumulation, and repressed expression of photosynthesis-related genes. On the other hand, the O genotype showed higher proline content, ascorbate peroxidase and catalase activities, especially under severe drought stress. Transcriptome analysis revealed the activation of plant hormone signal transduction pathway under mild water deficit and flavonoid biosynthesis pathway under severe drought stress in both genotypes. Our findings provide a theoretical basis for breeding drought-tolerant crops and implementing water-saving agriculture.

Summary: The study showed that early drought stress led to the most significant yield reductions, with water consumption being proportional to growth rate. Differences in water consumption and water use efficiency were observed among different sugar beet genotypes, but no genotype by water supply interaction was found.

Summary: An experiment was conducted to optimize different organic amendments for sugar beet production and root quality. Among the amendments, poultry manure at an optimized rate of 20 t ha(-1) showed the most effective results in terms of root yield, sugar yield, and sugar quality. The improved yield was attributed to better leaf growth and root yield, resulting in higher reserve accumulation in roots. The 'California' genotype performed better than the 'Serenada' genotype. Therefore, growing the 'California' genotype in sandy loam soils with poultry manure application (20 t ha(-1)) could be a practical option for improving sugar beet yield and sugar recovery.

Summary: Clarifying the differences in growth and yield responses to drought stress among different genotypes is important for developing superior dryland cultivars. Dryland genotypes showed greater biomass loss but minor yield loss under severe drought stress, while irrigated genotypes showed minor biomass loss but greater yield loss. Dryland genotypes exhibited better yield performance under both drought stress and well-watered conditions, indicating their possession of both drought tolerance and high yield potential traits. Metabolomics analysis revealed that irrigated genotypes accumulated proline which could be toxic to cells and resulted in enormous yield loss, while dryland genotypes increased beneficial amino acids and phenolic acids for enhancing cell self-protection and minimizing yield loss.
