Basmati rice grown in the Indian subcontinent is highly valued for its unique culinary qualities. Production is, however, often constrained by diseases such as bacterial blight (BB), blast and sheath (ShB). The present study developed with inbuilt resistance to BB, ShB using molecular marker-assisted selection. cultivar ‘Improved Pusa 1’ (carrying BB genes xa13 Xa21) was used recurrent parent ‘Tetep’ gene Pi54 quantitative trait loci (QTL), qSBR11-1) donor. Marker-assisted foreground...
Abstract Marker‐assisted simultaneous but stepwise backcross breeding ( MASS ‐ BB ) was utilized in the present study for pyramiding blast resistance genes, Piz5 and Pi54 , from non‐Basmati donors, C101A51 Tetep, respectively, into PRR 78, an elite Basmati restorer line of rice hybrid, Pusa RH 10. foreground selection coupled with stringent phenotypic background analysis carried out hastening recovery recurrent parent phenome RPP genome RPG two separate series to produce BC 2 F 1 plants...
Blast disease caused by Magnaporthe oryzae is a major constraint in rice production. Identification of new donors for blast resistance pre-requisite effective utilization diverse germplasm marker assisted incorporation into improved varieties. Therefore, the present study, set 100 accessions were evaluated 11 genes namely Pikm, Pik, Pikh, Pi1, Pi5, Pi54, Pib, Piz5, Piz, Pi9 and Pish, both at genotypic phenotypic level. Genotyping with gene based/gene linked markers could identify six...
Rice blast resistant gene, Pi54 cloned from rice line, Tetep, is effective against diverse isolates of Magnaporthe oryzae. In this study, we prospected the allelic variants dominant resistance gene a set 92 lines to determine nucleotide diversity, pattern its molecular evolution, phylogenetic relationships and evolutionary dynamics, develop allele specific markers. High quality sequences were generated for homologs gene. Using comparative sequence analysis, InDels variable sizes in all...
Basmati is a premium quality rice of India which highly priced in the international market. Pusa 1, an elite variety susceptible to blast caused by Magnaporthe oryzae. Therefore, pyramiding resistance genes essential effectively combat disease and increase durability genes. The Pi9 Pita have been earlier demonstrated be effective growing regions country. present study, monogenicnear isogenic lines 1637-18-7-6-20 1633-3-88-16-1 carrying Pita, respectively, were intercrossed generate pyramided...
Rice (Oryza sativa L.) crop confronts several major and minor diseases of which blast disease caused by Magnaporthe oryzae is a serious constraint causing moderate to huge economic losses world over. Exploitation genetic resistance in cultivars preferred management strategy. Though the number genes for have been cloned mapped, however, as because their variable efficacy donor traits there remains scope discovery alleles hence fresh donors among local collections landraces. Present...
Abstract Allelic variants of the broad-spectrum blast resistance gene, Piz-t, have been analyzed in 48 rice lines selected after phenotyping across three hot-spot regions India. Single Nucleotide Polymorhisms form transitions were more frequent than transversions alleles. On basis nucleotide polymorphism, 46 haplotypes identified, with major forming main haplogroups. The Piz-t alleles formed mostly region-specific clusters. Resistant and susceptible grouped into separate sub-clusters. value...
Rice blast caused by Magnaporthe oryzae is one of the most destructive diseases causing extensive yield loss throughout world. The present study deals with identification stress responsive genes in susceptible rice cultivar HR 12 after challenge M. oryzae. Transcript profiling using Affymetrix 57 K GeneChip revealed a total 72 differentially expressed whose expression level was significantly altered under diseased condition. Molecular function enrichment analysis suggested that regulated...
Globally, two major fungal diseases of rice,viz., blast caused by Magnaporthe oryzae and sheath blight incited Rhizoctonia solani Kuhn. occur in all agro-ecosystems resulting significant yield losses. In the present study, a set 100 rice lines were evaluated for resistance. Twenty seven genotypes identified to be resistant against M. isolate (Mo-ni-0066). However, evaluation these with highly virulent Karnataka (Mo-si-mnd) revealed that only viz., Bhusan San P1490-03 resistant. Same screened...
Wheat and Triticale rusts (leaf stem stripe) are important diseases in India other South Asian countries regions of world wherever wheat is cultivated.Rusts known to evolve over time space thus making it necessary breed new genotypes with combination resistant genes for effective management this menace.In India, the evaluation newly developed varieties against three initiates even before their entry coordinated yield trials besides, these initial advanced varietal at hot spot locations under...
