Marker–trait associations for physiological responses to irrigation and terminal drought stress in bread wheat using SSR and iPBS markers

Genome-wide association analysis of drought resistance and yield-related traits in maize inbred lines in Northwest China

Drought stress is a primary constraint on global maize production, significantly impairing plant growth, reproductive synchrony, and grain yield. To address this challenge, we aimed to identify SNPs and candidate genes associated with maize drought tolerance, with emphasis on grain yield (GY) and its drought resi...

Analysis of Genetic Variation, Correlation and Path Effects for Grain Yield Enhancement in Bread Wheat (Triticum aestivum L.) under Rainfed and Irrigated Conditions

Drought constrains wheat productivity, making the identification of genetically variable and yield-associated traits important for selection under contrasting moisture regimes. This study evaluated 50 advanced bread wheat genotypes, including five standard checks, under rainfed and irrigated environments during the Rab...

Identification of drought-tolerant and stable mung bean genotypes using stress tolerance indices

Mung bean (Vigna radiata L. Wilczek) is an important grain legume increasingly cultivated in water-limited environments. However, strong genotype × environment interaction (GEI) often complicates the identification of broadly adapted and drought-tolerant genotypes. This study integrated multi-environment phenotypic eva...

Assessment of Genetic Parameters and Multi-trait Selection for Morpho-physiological Characteristics in Drought-tolerant Maize

Background: Drought tolerance in maize is essential for stabilizing yields amid increasingly erratic rainfall patterns. This study aimed to estimate the heritability of agronomic and morpho-physiological traits, predict genetic gain under water stress and identify top-performing hybrids across varying drought intensiti...

Multi-environment genome-wide association study reveals genetic loci associated with drought tolerance during wheat germination

Identification of markers for yield and yield-related traits using association mapping analysis in rice (Oryza sativa L.) under rainfed conditions

Rice (Oryza sativa L.) grain yield is determined by multiple factors, including ideal plant architecture, appropriate flowering time and adaptability to diverse agro-climatic conditions. However, inadequate water availability in major rice-growing regions has led to increased incidence of drought and other abiotic stre...
