Among several important wheat foliar diseases, Stripe rust (YR), Leaf (LR), and Stem (SR) have always been an issue of concern to the farmers breeders. Evolution virulent pathotypes these rusts has posed frequent threats epidemic. Pyramiding rust-resistant genes are most economical environment-friendly approach in postponing this inevitable threat. To achieve durable long term resistance against three rusts, attempt study was made searching for novel sources resistant alleles a panel 483...
Abstract Genetic biofortification is recognized as a cost-effective and sustainable strategy to reduce micronutrient malnutrition. Genomic regions governing grain iron concentration (GFeC), zinc (GZnC), thousand kernel weight (TKW) were investigated in set of 280 diverse bread wheat genotypes. The genome-wide association (GWAS) panel was genotyped using 35 K Axiom Array phenotyped five environments. GWAS analysis showed total 17 Bonferroni-corrected marker-trait associations (MTAs) nine...
Genomic regions governing days to heading (DH), grain filling duration (GFD), number per spike (GNPS), weight (GWPS), plant height (PH), and yield (GY) were investigated in a set of 280 diverse bread wheat genotypes. The genome-wide association studies (GWAS) panel was genotyped using 35K Axiom Array phenotyped five environments. GWAS analysis showed total 27 Bonferroni-corrected marker-trait associations (MTAs) on 15 chromosomes representing all three subgenomes. GFD the highest MTAs (8),...
Identification of marker trait association is a prerequisite for marker-assisted breeding. To find markers linked with traits under heat and drought stress in bread wheat (Triticum aestivum L.), we performed genome-wide study (GWAS). GWAS mapping panel used this consists advanced breeding lines from the IARI programme produced by pairwise complex crosses. Phenotyping was done at multi locations namely New Delhi, Karnal, Indore, Jharkhand Pune augmented-RCBD design different moisture regimes,...
Abstract Background Wheat rusts are important biotic stresses, development of rust resistant cultivars through molecular approaches is both economical and sustainable. Extensive phenotyping large mapping populations under diverse production conditions high-density genotyping would be the ideal strategy to identify major genomic regions for resistance in wheat. The genome-wide association study (GWAS) population 280 genotypes was genotyped using a 35 K Axiom single nucleotide polymorphism...
Genomic regions governing grain protein content (GPC), 1000 kernel weight (TKW), and normalized difference vegetation index (NDVI) were studied in a set of 280 bread wheat genotypes. The genome-wide association (GWAS) panel was genotyped using 35K Axiom array phenotyped three environments. A total 26 marker-trait associations (MTAs) detected on 18 chromosomes covering the A, B, D subgenomes wheat. GPC showed maximum MTAs (16), followed by NDVI (6), TKW (4). 10 located B subgenome, whereas, 8...
Leaf or brown rust caused by Puccinia triticina (Pt) is one of the most important diseases wheat. Among rusts, it ubiquitous in all wheatgrowing regions and causes considerable yield loss. Microsatellite marker-based genotyping virulence- based phenotyping 48 pathotypes Pt was performed. The exhibit low virulence frequencies for Indian leaf differentials Lr24, Lr9, Lr10, Lr19, Lr28 Lr9 . Using avirulence/virulence formula six major clusters were observed, revealing high degree phenotypic...
Wheat is the second most cultivated cereal crop in world and an important India. Leaf (brown) rust, caused by Puccinia triticina, was prevalent among three rusts found all wheat-growing areas of India, Bhutan, Nepal during 2016 to 2019. rust samples from wheat crops these countries were pathotyped using differential genotypes binomial Indian system nomenclature. To facilitate international communication, each pathotype identified also tested North American differentials. A total 33...
High temperature during reproductive stage of winter crops causes sterility pollen grains and reduced yield. It is essential to find the genotypes with higher viability, as it most sensitive extremes. A field study was conducted wheat (Triticum aestivum L.) understand effect high on viability grain yield for 2years under timely (TS) late sown (LS) conditions. strong correlation observed between heat stress condition. Genotypes like K7903, HD2932, WH730 RAJ3765 showed whereas DBW17, HUW468,...
Wheat stem rust, caused by Puccinia graminis f. sp. tritici (Pgt), has re-emerged as one of the major concerns for global wheat production since evolution Ug99 and other virulent pathotypes Pgt from East Africa, Europe, Central Asia, regions. Host resistance is most effective, economic, eco-friendly approach managing rust. Understanding virulence nature, genetic diversity, origin, distribution, evolutionary pattern over time space a prerequisite effectively newly emerging isolates through...
Wheat is an important constituent of human diet worldwide. India the second largest producer wheat in world and directly related to economic health country. To meet food requirements growing population, there a need increase production. rusts caused by fungus Puccinia species are main biotic constraints our efforts sustain boost historic devastating pathogens Their ability spread aerially over continents, production infectious pustules geometrically trillions evolving new physiologic forms,...
