SSR marker-assisted diversity in advance breeding lines of bread wheat and superior allele identification for heat tolerance

Assessment of molecular genetic diversity in wheat (Triticum aestivum L.) genotypes for identifying heat-tolerant and heat-susceptible varieties using chromosome specific SSR markers

Identifying genetically diverse and heat-tolerant wheat germplasm is essential for developing climate-resilient cultivars under rising global temperatures. In this study, 30 wheat (Triticum aestivum L.) genotypes were characterised using twenty chromosome-specific simple sequence repeat (SSR) markers to assess molecula...

Assessment of genetic diversity, vernalization alleles, and heat tolerance markers in bread wheat lines under water stress conditions

Bread wheat is considered one of the most important crops in Egypt and worldwide and improving its productivity under water stress is a major breeding objective. This study aimed to evaluate advanced bread wheat lines under water stress and to characterize heat shock protein (HSP) and vernalization (Vrn) genes, as well...

Association of SSR Markers on 2D Chromosome of Bread Wheat with Drought Tolerance

DECIPHERING MOLECULAR DIVERSITY AND GENETIC RELATIONSHIPS IN BREAD WHEAT GERMPLASM USING SSR MARKERS

The observed molecular differentiation demonstrated the presence of genetically diverse material within the studied germplasm and may be useful for germplasm characterization and selection of diverse parents to broaden the genetic base of wheat breeding programmes.

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...

Integrating multi-trait selection indices and molecular marker-based diversity analysis for identification of yield and nutritional quality traits in pearl millet ( Pennisetum glaucum L.)

Background : Pearl millet ( Pennisetum glaucum L.) is a resilient C 4 cereal adapted to arid and semiarid regions and is recognized as a climate-smart crop with considerable nutritional potential. Germplasm characterization provides a foundation for genetic improvement and marker-assisted breeding. This study...
