Two major bacterial blight (BB) resistance genes (Xa21 and xa13) a gene for blast (Pi54) were introgressed into an Indian rice variety MTU1010 through marker-assisted backcross breeding. Improved Samba Mahsuri (possessing Xa21 NLR145 Pi54) used as donor parents. Marker-assisted backcrossing was continued till BC2 generation wherein PCR based functional markers specific the foreground selection set of parental polymorphic microsatellite background at each stage backcrossing. Selected BC2F1...
Unfavorable climatic changes have led to an increased threat of several biotic and abiotic stresses over the past few years. Looking at massive damage caused by these stresses, we undertook a study develop high yielding climate-resilient rice, using genes conferring resistance against blast (Pi9), bacterial leaf blight (BLB) (Xa4, xa5, xa13, Xa21), brown planthopper (BPH) (Bph3, Bph17), gall midge (GM) (Gm4, Gm8) QTLs for drought tolerance (qDTY1.1 qDTY3.1) through marker-assisted forward...
Broadening of the genetic base for identification and transfer genes resistance to insect pests diseases from wild relatives rice is an important strategy in breeding programs across world. An accession Oryza nivara, International Rice Germplasm Collection (IRGC) number 105710, was identified exhibit high level broad-spectrum Xanthomonas oryzae pv. oryzae. In order study genetics tag map gene or present IRGC it crossed with bacterial blight (BB)-susceptible varieties 'TN1' 'Samba Mahsuri'...
Bacterial blight (BB) and fungal blast diseases are the major biotic constraints that limit rice productivity. To sustain yield improvement in rice, it is necessary to developed potential of varieties by incorporation stress resistance genes. Tellahamsa a well-adapted popular high yielding variety Telangana state, India. However, highly susceptible BB blast. In this study, simultaneous stepwise transfer genes through marker-assisted backcross breeding (MABB) strategy was used introgress two...
Rice blast and bacterial leaf blight, are major disease, significantly threatens rice yield in all growing regions under favorable conditions identification of resistance genes their superior haplotypes is a potential strategy for effectively managing controlling this devastating disease. In study, we conducted genome-wide association study (GWAS) using diverse set 147 accessions blight diseases replications. Results revealed 23 (9 14 BLB) significant marker-trait associations (MTAs) that...
Abstract Xanthomonas oryzae pv. ( Xoo ) is a serious pathogen of rice causing bacterial leaf blight disease. Resistant varieties and breeding programs are being hampered by the emergence highly virulent strains. Herein we report population based whole genome sequencing analysis 100 strains from India. Phylogenomic revealed clustering India along with other Asian strains, distinct African US Xo The Indian consists major clonal lineage four minor but diverse lineages. Interestingly, variant...

Bacterial blight (BB) in rice caused by Xanthomonas oryzae pv. (Xoo) is a major global production constraint, particularly irrigated and rain-fed lowland areas. Improved Samba Mahsuri (ISM) an elite, high-yielding, fine-grain type, BB-resistant variety possessing three genes (Xa21, xa13 xa5) highly popular the southern parts of India. As BB pathogen dynamic evolution virulence against deployed resistance common, we added novel gene, Xa38, into ISM through marker-assisted backcross breeding...

Abstract Background Rhizoctonia solani is a polyphagous fungal pathogen that causes diseases in crops. The strains are classified into anastomosis groups (AGs); however, genomic complexity, diversification the AGs and evolution of pathogenicity-associated genes remain poorly understood. Results We report recent whole-genome duplication sequential segmental duplications AG1-IA R. . Transposable element (TE) clusters have caused loss synteny duplicated blocks introduced differential structural...
Bacterial Blight (BB) is the most serious bacterial disease of rice. Usage resistant cultivars has been a successful strategy in controlling BB. However, constant selection pressure causes evolution hypervirulent pathogenic strains that break down resistance, thus necessitating additional sources resistance. An induced-mutant line derived from elite rice cultivar Samba Mahsuri was identified to exhibit broad-spectrum resistance Using next-generation gene mapping approaches, we genomic...
In marker-assisted breeding for bacterial blight (BB) resistance in rice, three major genes, viz., Xa21, xa13 and xa5, are routinely deployed either singly or combinations. As efficient functional markers yet to be developed we have simple PCR-based both the genes. For xa13, designed a marker, xa13-prom targeting InDel polymorphism promoter of candidate gene Os8N3 located on chromosome 8 rice. With respect multiplex-PCR based marker system, named xa5FM, consisting two sets primer pairs 2-bp...
Developing rice (Oryza sativa L.) cultivars with resistance to bacterial leaf blight (BLB) and blast is crucial for ensuring food security, as these diseases can cause significant yield losses. Additionally, enhancing potential in resistant maximize productivity meet the growing demand rice; therefore, introgression of genes along improvement most felicitous strategy a panoramic genetic enhancement. Jaya popular, stable mega variety, notified cultivated 19 states across India, susceptible...
Abstract IR 58025A is a very popular wild‐abortive cytoplasmic male sterile ( WA ‐ CMS ) line of rice and extensively used for hybrid breeding. However, many hybrids derived from it possess mild aroma (undesirable in some parts India) are highly susceptible to bacterial blight BB blast diseases. To improve resistance, we have introgressed major dominant gene conferring resistance against (i.e. Xa21 Pi54 into 58025B, the maintainer 58025A. An introgression Samba Mahsuri SM 2154) possessing...
Bacterial blight (BB) disease reduces the yield of rice varieties and hybrids considerably in many tropical growing countries like India. The present study highlights development durable BB resistance into background an elite maintainer rice, DRR17B, by incorporating two major dominant genes, Xa21 Xa33 through marker-assisted backcross breeding (MABB). Through sets backcrosses, genes were transferred separately to DRR17B. In this process, at each stage backcrossing, foreground selection was...
Bacterial blight disease of rice caused by Xanthomonas oryzae pv. (Xoo) is one the most serious constraints in production. The sustainable strategy to combat deployment host plant resistance. Earlier, we identified an introgression line, IR 75084-15-3-B-B, derived from Oryza officinalis possessing broad-spectrum resistance against Xoo. In order understand inheritance O. accession and identify genomic region(s) associated with resistance, a recombinant inbred line (RIL) mapping population was...
RPHR-1005, the stable restorer line of popular medium slender (MS) grain type rice hybrid, DRRH-3 was improved in this study for resistance against bacterial blight (BB) and blast diseases through marker-assisted backcross breeding (MABB). In study, four major genes (i.e., Xa21 Xa33 BB Pi2 Pi54 resistance) have been transferred to RPHR-1005 using RPBio Patho-1 (possessing + ), Patho-2 ) FBR1-15EM as donors.
