“…Due to the direct influence of branch number on silique number, QTLs/QTNs for branch number should also be considered. Twenty‐seven QTLs/QTNs for branch number have been identified in seven studies since 2015 (He et al ., 2017 ; Li et al ., 2016 , 2020a , 2022a ; Liu et al ., 2021 ; Luo et al ., 2015 ; Zheng et al ., 2017 ). In total, 174 QTLs/QTNs for traits related to silique number have been described.…”

SummarySilique number is a crucial yield‐related trait for the genetic enhancement of rapeseed (Brassica napus L.). The intricate molecular process governing the regulation of silique number involves various factors. Despite advancements in understanding the mechanisms regulating silique number in Arabidopsis (Arabidopsis thaliana) and rice (Oryza sativa), the molecular processes involved in controlling silique number in rapeseed remain largely unexplored. In this review, we identify candidate genes and review the roles of genes and environmental factors in regulating rapeseed silique number. We use genetic regulatory networks for silique number in Arabidopsis and grain number in rice to uncover possible regulatory pathways and molecular mechanisms involved in regulating genes associated with rapeseed silique number. A better understanding of the genetic network regulating silique number in rapeseed will provide a theoretical basis for the genetic improvement of this trait and genetic resources for the molecular breeding of high‐yielding rapeseed.

“…A semi-dwarf stature with narrow branch angles rapeseed mutant was characterized by ethyl methanesulfonate (EMS)-mutagenized, which would be valuable for breeding superior rapeseed hybrid cultivars and the yield increase in other Brassica crops [19]. Various Quantitative trait loci (QTL) for rapeseed branching were identified by using the traditional QTL-mapping [20,21]. The candidate genes for dwarf and compact plant architecture rapeseed were identified combined BSA-Seq based mapping and RNA-Seq profiling [22].…”

As a desirable agricultural trait, multi-inflorescence (MI) fulfills the requirement of mechanized harvesting and yield increase in rapeseed (Brassica napus L.). However, the genetic mechanism underlying the multi-inflorescence trait remain poorly understood. We previously identified a difference of one pair of dominant genes between the two mapping parental materials. In this study, phenotype and expression analysis indicated that the imbalance of the CLAVATA (CLV)-WUSCHEL (WUS) feedback loop may contribute to the abnormal development of the shoot apical meristem (SAM). BnaMI was fine-mapped to a 55 kb genomic region combining with genotype and phenotype of 5768 BCF1 individuals using a traditional mapping approach. Through comparative and expression analyses, combined with the annotation in Arabidopsis, five genes in this interval were identified as candidate genes. The present findings may provide assistance in functional analysis of the mechanism associated with multi-inflorescence and yield increase in rapeseed.
