Mapping quantitative trait loci (QTLs) for plant architecture traits using a high-density genetic linkage map in diploid potato (Solanum chacoense)

Genome-Wide Mapping Reveals Major and Stable Quantitative Trait Loci for Seed Oil Content in Soybean

Seed oil content is one of the primary breeding objectives in soybean. However, the genetic basis of seed oil content remains largely unexplored. In this study, we employed a recombinant inbred line (RIL) population consisting of 201 lines derived from a cross between Feidong and Guanyun, to identify quantitative trait...

Quantitative trait loci and genome-wide association study identifies novel loci for plant height in pepper (Capsicum spp.)

Plant height (PH) is a key trait that influences photosynthetic efficiency, early maturity, lodging resistance, and crop yield. The development of plant factories and mechanical harvesting has increased the demand for peppers ( Capsicum spp.) with suitable plant architecture. In this study, we performed quantitativ...

Genome wide association mapping and haplotype analysis identify genetic loci and candidate genes associated with yield related traits in rice (Oryza sativa L.)

Rice (Oryza sativa L.) is one of the most important staple crops worldwide, and improving grain yield remains a major objective of rice breeding programs. Yield is a complex quantitative trait influenced by multiple agronomic characteristics, including grain yield per plant (GY), seed setting rate (SSR), plant height (...

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

QTL mapping and candidate gene analysis of berry and cluster traits in table grapevine bred for warm climates

Table grapes are a valuable fruit crop worldwide. Warm climates are emerging as important global production suppliers. Traditional grapevine cultivars are poorly adapted to higher temperatures and other abiotic factors of warm zones, conditions increasingly common in temperate areas due to climate change. Understanding...

QTL detection for fruit commercial quality traits in diploid and triploid banana populations

Desert bananas (Musa spp.) are a major fruit crop worldwide for which postharvest quality traits are major determinants for consumer acceptance and adoption of new cultivars. They are thus important targeted traits in breeding yet their genetic basis remains poorly characterized. We report the first QTL mapping study o...
