Enhancement of genetic gain for early seedling vigor traits through marker-assisted pedigree selection in rice ( L.).

Unlabelled: Early Seedling Vigor (ESV) is a critical trait for direct-seeded rice (DSR), as it promotes rapid seedling establishment and effective weed suppression. Enhancing ESV is therefore essential for developing varieties adapted to DSR conditions. This study aimed to accelerate genetic gain for ESV traits through Marker-Assisted Pedigree Selection (MAPS) by leveraging reported quantitative trait loci (QTLs).

Genetic analysis of trade-offs among disease resistance, yield, and quality traits employing genome-wide association mapping in indica rice ( L.).

Unlabelled: The genetic trade-offs among complex traits are often witnessed in rice, however, very little is known about the contributing genes and mechanisms to exploit in breeding programmes. Here, we aimed to understand the genetic trade-offs among disease resistance, quality, and yield traits employing genome-wide association mapping. In all, 78 common marker-trait associations (MTAs) were identified for the targeted traits.

Discovery of genomic regions and candidate genes for grain weight employing next generation sequencing based QTL-seq approach in rice (Oryza sativa L.).

Rice (Oryza sativa L.) yield enhancement is one of the prime objectives of plant breeders. Elucidation of the inheritance of grain weight, a key yield component trait, is of paramount importance for raising the yield thresholds in rice.
