“…S‐12 is known for its good lint quality, late maturity and high yield potential (Imran et al, 2011) but is extremely susceptible to CLCuD (Hussain et al, 2012). All the plants in the F1 hybrid population were tolerant to CLCuD, implying that there may be a dominant gene(s) conferring resistance to CLCuD, as reported earlier (Ahuja et al, 2007; Khan, 2013; Vij et al, 2022). Various studies have reported that major genes control resistance against CLCuD.…”

“…Various molecular markers have been employed to create genetic linkage maps in cotton, which produced high‐density linkage maps with a marker span reaching 5115.16 cM and an average marker interval of 0.5–1 cM (Gu et al, 2020; Zhang et al, 2019). Some studies are available to map CLCuD resistance through QTL mapping using intra‐ and interspecific crosses (Vij et al, 2022). Among different molecular markers available, random amplified polymorphic DNA (RAPD) markers could not show any polymorphism in the F2 segregating population (Rahman et al, 2005).…”

Cotton leaf curl disease (CLCuD) is a major threat to cotton production in Asia and Africa. Using marker‐assisted breeding can be the best sustainable approach to tackle CLCuD. Identification of new QTLs in the indigenous cotton germplasm is necessary to combat CLCuD. The current study was designed to construct a genetic linkage map of bi‐parental F2:F3 populations developed from highly tolerant MNH‐886 and highly susceptible S‐12 cotton cultivars. One hundred seven CLCuD‐associated simple sequence repeat (SSR) marker alleles were identified as polymorphic and three new QTLs were found on chromosomes C11, C19 and C21. Two QTLs on chromosomes C11 and C19 were detected in both F2 and F3 populations in the region flanked by SSR markers CIR316 and BNL4094, and BNL285 and BNL3348, respectively. Whereas, one QTL on chromosome C21 was detected in the region flanked by SSR markers JESPR158 and JESPR135 in both F2 and F3 generations. The CLCuD‐associated QTLs identified in this study can help fine‐tune the molecular mapping of the QTLs on the cotton genome against CLCuD.

“…Some reports have demonstrated that a single dominant gene contributes to CLCuD resistance, while others have shown that two or even three genes may contribute to CLCuD resistance in different sources of upland cotton germplasm. The reason for this foregoing dissension may be attributed to different parental populations employed in the genetic analysis(Vij et al 2022). It is factual that the dominant mode of resistance against geminiviruses has a narrow genetic base and is vulnerable to the constantly evolving geminiviruses(Vidya et al 2020).…”

Cotton leaf curl disease (CLCuD), caused by begomoviruses, is a major threat to cotton (Gossypium hirsutum L.) production, especially in Asia and Africa. The use of marker-assisted breeding to utilize host plant resistance can be the best sustainable approach to tackle CLCuD. Because most of the available cotton germplasm is susceptible to CLCuD, so it demands the identification of potentially new quantitative trait loci (QTLs) in the indigenous germplasm. The current study was designed to construct a broader genetic linkage map of bi-parental F2:F3 populations developed from a highly tolerant MNH 886 and a highly susceptible S-12 cotton cultivars. One hundred seven (107) CLCuD-associated simple sequence repeat (SSR) marker alleles were identified as polymorphic and eight new QTLs were found on chromosomes 11, 19 and 21. On homologous chromosomes 11 and 17, the QTLs qCL-11-120d2 and qCL-21-m2 were detected in both F2 and F3 populations. Another QTL on chromosome 11, qCL-11-m3, showed the highest phenotypic variance (PV%) of 16.66% and LOD score > 3. Other QTLs on chromosome 11 were qCL-11-m2, qCL-11-120d3. On chromosome 19, three QTLs (qCL-19-m2, qCL-19-90d2 and qCL-19-120d3) were detected with PV% >8 and LOD score > 3. The CLCuD-associated QTLs identified in this study can contribute to develop CLCuD-resistant cultivars using marker assisted selection and can help to fine-tune the molecular mapping of the QTLs on the cotton genome.

“…While pedigree research revealed that several cultivars were created through interspecific hybridization, a molecular study using isozymes and DNA markers revealed that the Upland cotton gene pool is rather uniform. Rare alleles are found in just a few closely related cultivars within a germplasm group and are thought to have evolved by introgression [6,104]. Furthermore, none of these G. barbadense -introgressed alleles were discovered in current cotton cultivars, suggesting that the advantages of G. barbadense introgression in Upland cotton are still completely unmet.…”

Inter-Specific Hybridization in Cotton (Gossypium hirsutum) for Crop Improvement

Interspecific hybridization has contributed significantly to land diversity, species evolution, and crops' domestication, including upland cotton, the cultivated form ofGossypium hirsutum . Being the world's most important fiber crop species, Gossypium hirsutum belongs to the allotetraploid Gossypium consisting of six additional tetraploid species. The lint fiber evolved once in diploid parent A-genome species in theGossypium 's history and passed on during hybridization of the A-genome with the D-genome and was maintained in subsequent evolution. The domestication history of G. hirsutum involved the collection and use of lint fibers by indigenous people for the purpose of making strings and other textile products; hence, spinnable lint fibers were likely to have evolved under domestication. Crossing with G. barbadense has resulted in the development of multiple genetic lines in contemporary upland cotton. However, in latergeneration hybrids betweenG. hirsutum and other polyploid species, reproductive barriers such as reduced fertility, segregation distortion, and hybrid breakdown are frequently observed, complicating the task of introgressing new, stably inherited allelic variation from inter-specific hybridization. Recent efforts in molecular genetics research have provided insights into the location and effects of QTLs from wild species that are associated with traits important to cotton production. These and future research efforts will undoubtedly provide the tools that can be utilized by plant breeders to access novel genes from wild and domesticated allotetraploid Gossypium for upland cotton improvement.
