“…It was transferred from B. napus to Ogura CMS B. rapa , and its location on the chromosome was identified by BAC-FISH technology [ 138 ]. In B. juncea , the Rfo gene was located in an ~108 kb radish chromosome fragment, which was positioned amidst a large C-genome translocation at the distal part of chromosome A09, and an intragenic KASPar marker (KASP-RFO-1814) for the marker-aided transfer of Rfo was developed [ 99 , 140 ].…”

Hybrid production using lines with cytoplasmic male sterility (CMS) has become an important way to utilize heterosis in vegetables. Ogura CMS, with the advantages of complete pollen abortion, ease of transfer and a progeny sterility rate reaching 100%, is widely used in cruciferous crop breeding. The mapping, cloning, mechanism and application of Ogura CMS and fertility restorer genes in Brassica napus, Brassica rapa, Brassica oleracea and other cruciferous crops are reviewed herein, and the existing problems and future research directions in the application of Ogura CMS are discussed.

“…One CG, gene-KK1_011505, located on CC_MQTL6.1, encodes the pentatricopeptide repeat proteins. These are sequence-speci c RNA-binding proteins that recruit mitochondrial RNA processing machinery and thus aid in the regulation of fertility restoration by processing proteins or mRNAs produced by male sterility genes (Gudi et al 2020).…”

A meta-analysis of quantitative trait loci (QTLs) associated with agronomic traits, fertility restoration, disease resistance, and seed quality traits, was conducted for the first time in pigeonpea. Data on 498 QTLs was collected from 9 linkage mapping studies (involving 21 bi-parental populations). Of these 498, 203 QTLs were projected onto "PigeonPea_ConsensusMap_2022," saturated with 10,522 markers, which resulted in the prediction of 34 meta-QTLs (MQTLs). The average confidence interval (CI) of these MQTLs (2.54 cM) was 3.37-times lower than the CI of the initial QTLs (8.56 cM). Of the 34 MQTLs, 12 high-confidence MQTLs with smaller CI (≤ 5 cM) and a greater number of initial QTLs (≥ 5) were utilized to extract 2,255 gene models, of which 105 were believed to be associated with different traits. The comparison of physical coordinates of MQTLs and marker trait associations reported from genome-wide association studies enabled the validation of eight MQTLs. Furthermore, synteny and ortho-MQTL analysis among pigeonpea and four related legumes crops such as chickpea, pea, cowpea, and french bean led to the identification 117 orthologous genes from 20 MQTL regions. Flanking markers of identified MQTLs can be employed for MQTL-assisted breeding as well as to improve the prediction accuracy of genomic selection in pigeonpea. Furthermore, genes identified in this study could be potential targets for positional cloning and functional analysis to unveil the molecular mechanisms underlying the target traits.

“…Linkage drag may introduce undesirable traits such as delayed maturity, pod shattering, unappealing seed coat colour and texture, anti-nutritional factors, etc., along with the trait of interest. Several backcrosses are required to reduce such linkage drags, which is the most time and resource-consuming part of IL development process ( Figure 3 ) ( Sharma et al., 2013 ; Gudi et al., 2020 ). However, breeders can employ modern breeding approaches, including marker-assisted backcrossing (MABC), to purge the linkage drag and also to speed up the recovery of recurrent parent genome ( Figure 2 ).…”

The fluctuating climates, rising human population, and deteriorating arable lands necessitate sustainable crops to fulfil global food requirements. In the countryside, legumes with intriguing but enigmatic nitrogen-fixing abilities and thriving in harsh climatic conditions promise future food security. However, breaking the yield plateau and achieving higher genetic gain are the unsolved problems of legume improvement. Present study gives emphasis on 15 important legume crops, i.e., chickpea, pigeonpea, soybean, groundnut, lentil, common bean, faba bean, cowpea, lupin, pea, green gram, back gram, horse gram, moth bean, rice bean, and some forage legumes. We have given an overview of the world and India’s area, production, and productivity trends for all legume crops from 1961 to 2020. Our review article investigates the importance of gene pools and wild relatives in broadening the genetic base of legumes through pre-breeding and alien gene introgression. We have also discussed the importance of integrating genomics, phenomics, speed breeding, genetic engineering and genome editing tools in legume improvement programmes. Overall, legume breeding may undergo a paradigm shift once genomics and conventional breeding are integrated in the near future.
