A Systemic Investigation of Genetic Architecture and Gene Resources Controlling Kernel Size-Related Traits in Maize

Cheng Wang et al.

Summary: Grain yield is a critical and complex trait in maize, and the size of the kernel, including length, width, thickness, and hundred-kernel weight, plays an important role in this trait. Numerous QTLs and QTNs have been identified for controlling these traits, but only some have been successfully utilized in breeding programs. In this study, we collected reported genes, QTLs, and QTNs associated with kernel size-related traits and identified 31 hotspots that can be further explored for fine mapping and candidate gene validation. This study not only facilitates the cloning of causal genes but also provides guidance for breeding practices in maize.

Introgression Lines: Valuable Resources for Functional Genomics Research and Breeding in Rice (Oryza sativa L.)

Bo Zhang et al.

Summary: Introgression lines (ILs) developed by a backcross strategy combined with marker-assisted selection (MAS) are powerful tools for broadening the genetic base of modern rice varieties. They have high power for mapping quantitative trait loci (QTLs) and can be used to evaluate the genetic effects of QTLs and detect gene-by-gene or gene-by-environment interactions. ILs developed from multiple donors in a fixed background can be used as a platform to identify the best alleles or allele combinations for breeding.

Genetic architecture of embryo size and related traits in maize

Xiaowei Li et al.

Summary: The embryo in maize plays a critical role in controlling kernel nutrition components and grain yield. The genetic architecture of maize embryo size and its related traits is dominated by multiple small-effect loci with little epistasis. Several key loci associated with multiple traits, including cloned maize genes and maize orthologs of known rice genes, were identified. The findings provide a foundation for improving embryo-size-mediated kernel nutrition and grain yield.

Maize kernel development

Dawei Dai et al.

Summary: Maize kernel development is initiated by double fertilization, leading to the formation of a mature kernel comprised of embryo, endosperm, and pericarp. With the release of the maize reference genome and advancements in genomic technologies, there has been a rapid expansion of new knowledge in maize kernel development.

Fine mapping of a kernel length-related gene with potential value for maize breeding

Dianming Gong et al.

Summary: Kernel size is a crucial factor affecting yield in cereals, with kernel length being a key determining factor. A novel major QTL, qKL9, controlling maize kernel length was identified and confirmed through various population tests. This QTL shows promising potential for genetic improvement in maize kernel-related traits.

Genetic Dissection of Grain Yield of Maize and Yield-Related Traits Through Association Mapping and Genomic Prediction

Juan Ma et al.

Summary: This study focused on maize breeding aiming for high yield, using genomic dissection and prediction methods to understand and improve grain yield. Two GWAS methods were applied on an association panel of 309 inbred lines, revealing significant trait-marker associations. The RKHS model showed better performance in predicting yield-related traits, while GBLUP performed slightly better for certain traits. The incorporation of significant single-nucleotide polymorphisms improved prediction accuracy, with TAMs showing effectiveness in improving accuracy for GYP and yield-related traits.
