QTL mapping for root traits during post-tillering stage under moisture-deficit stress in wheat

Genetic dissection and QTL validation of seedling root system architecture in Chinese wheat landraces

Genetic Dissection and Fine-Mapping of QTL for Salinity Tolerance at the Reproductive Stage on Chromosome 2 of Rice Variety Nona Bokra

Soil salinity is a major constraint limiting rice productivity, particularly at the reproductive stage. To elucidate the genetic basis of reproductive stage salinity tolerance, this study validated and fine-mapped quantitative trait loci (QTL) for yield-related traits using a salinity-tolerant line SL506, identified th...

QTL mapping and haplotype analysis reveal candidate genes for seedling-stage salinity tolerance in rice

Introduction Soil salinization is a major constraint on rice production, and severe salinity levels lead to pronounced yield losses. Therefore, elucidating the genetic architecture of salinity tolerance and identifying candidate genes underlying this trait are crucial for molecular design breeding. Methods In this stud...

From Seedling Architecture to Grain: Linking Root and Shoot Traits with Yield Potential for Climate-Resilient Wheat Breeding

Improving wheat for climate change requires understanding how seedling root systems affect adult plant performance. We evaluated 116 spring bread wheat (Triticum aestivum L.) genotypes across 25 traits under non-limiting moisture conditions. Analysis of variance revealed significant genotypic variation (p < 0.01) for a...

QTL Mapping for Leaf Rust Resistance in a Wheat Recombinant Inbred Line Population of Liang66-S/Hengmai28

Leaf rust (LR), caused by Puccinia triticina, is a major constraint to global wheat production. Identifying quantitative trait loci (QTLs), conferring adult-plant resistance (APR), and developing breeder-friendly markers are essential for durable disease control. In this study, a recombinant inbred line (RIL) populatio...
