Miniature inverted-repeat transposable elements (MITEs) are a group of class II transposable elements. The MITE Monkey King (MK) was first discovered upstream of BnFLC.A10.

- Genome-wide association studies (GWASs) were conducted using extensive genomic data to identify genetic factors influencing three seed-quality traits in rapeseed: erucic acid content, glucosinolate content, and seed oil content.
- The study generated a detailed genomic variation map featuring over 4.5 million SNPs and around 629,000 INDELs, leading to the identification of 72 loci significantly associated with the seed-quality traits across various environments.
- The findings revealed a strong correlation between the presence of favorable alleles at these loci and phenotypic variation, aiding in the development of breeding strategies for enhanced seed quality in rapeseed.
Association mapping of six yield‑related traits in rapeseed (Brassica napus L.).

Yield is one of the most important traits for rapeseed (Brassica napus L.) breeding, but its genetic basis remains largely ambiguous. Association mapping has provided a robust approach to understand the genetic basis of complex agronomic traits in crops.

In this study, we assessed the genetic diversity, population structure and the extent of LD in a panel of 192 inbred lines of Brassica napus from all over the world using 451 single-locus microsatellite markers. The inbred lines could be divided into P1 and P2 groups by a model-based population structure analysis.

The objective of this research was to evaluate a collection of 86 oilseed rape cultivars with 188 simple sequence repeat (SSR) markers to assess the genetic variability, heterotic group identity and relationships within and between the groups identified among the genotypes. A total of 631 alleles at 188 SSR markers were detected including 53 and 84 unique and private alleles respectively, which indicated great richness and uniqueness of genetic variation in these selected cultivars.
