Abstract The value of exotic wheat genetic resources for accelerating grain yield gains is largely unproven and unrealized. We used next-generation sequencing, together with multi-environment phenotyping, to study the contribution genomes 984 three-way-cross-derived (exotic/elite1//elite2) pre-breeding lines (PBLs). Genomic characterization these haplotype map-based SNP marker approaches revealed specific imprints 16.1 25.1%, which compares theoretical expectation 25%. A rare favorable (GT)...
Abstract Climate change and slow yield gains pose a major threat to global wheat production. Underutilized genetic resources including landraces wild relatives are key elements for developing high-yielding climate-resilient varieties. Landraces introduced into Mexico from Europe, also known as Creole wheats, adapted wide range of climatic regimes represent unique resource. Eight thousand four hundred sixteen representing all dimensions were characterized through genotyping-by-sequencing...
Aegilops tauschii, the D-genome progenitor of Triticum aestivum, encompasses huge diversity for various traits potential economic importance such as yield, biotic and abiotic stress tolerance, quality nutrition. In present study, variation grain size in Ae. tauschii germplasm was studied its genetic basis dissected using genome wide association study (GWAS). Grain length, width weight evaluated 177 accessions over three years showed near normal distribution with 1.74, 1.75 2.82-fold...
Aegilops umbellulata , a non‐progenitor diploid species, is an excellent source of resistance to various wheat diseases. Leaf rust and stripe genes from A. were transferred the susceptible cultivar WL 711 through induced homoeologous pairing. A doubly resistant introgression line IL 393‐4 was crossed with PBW 343 develop mapping population. Tests on BC 2 F 7 RIL s indicated monogenic inheritance seedling leaf in respective co‐segregating tentatively named LrUmb YrUmb . Bulked segregant...
Wheat variety PBW343, released in India 1995, became the most widely grown cultivar country by year 2000 owing to its wide adaptability and yield potential. It initially succumbed leaf rust, resistance genes Lr24 Lr28 were transferred PBW343. After an unbroken reign of about 10 years, virulence against gene Yr27 made PBW343 susceptible stripe rust. Owing potential, prime target for marker-assisted introgression rust genes. The rust-resistant versions formed base pyramiding Yr5, Yr10, Yr15,...
Abstract Micronutrient malnutrition affects a very large proportion of the world's population. For combating micronutrient malnutrition, biofortification through genetic manipulation has been proposed as an alternative to traditional fortification for increasing bioavailable nutrient content food crops. Wheat, being staple section population, is targeted Fe and Zn in grains. The cultivated germplasm wheat does not have sufficient variability grain but wild species do show wider variation...
A comprehensive germplasm evaluation study of wheat accessions conserved in the Indian National Genebank was conducted to identify sources rust and spot blotch resistance. comprising three species wheat-Triticum aestivum, T. durum dicoccum were screened sequentially at multiple disease hotspots, during 2011-14 crop seasons, carrying only resistant next step evaluation. Wheat which found be field then assayed for seedling resistance profiled using molecular markers. In primary evaluation,...
The inconsistent prevalence of abiotic stress in most the agroecosystems can be addressed through deployment plant material with adaptive plasticity. present study explores water induced plasticity for early root-shoot development, proline induction and cell membrane injury 57 accessions Aegilops tauschii (DD-genome) 26 Triticum dicoccoides (AABB-genome) along durum bread wheat cultivars. Thirty three Ae. 18 T. showed an increase root dry weight (ranging from 1.8 to 294.75%) under stress....
Utilization of "hidden genes" from wild species has emerged as a novel option for enrichment genetic diversity productivity traits. In rice we have generated more than 2000 lines having introgression 'A' genome-donor in the background popular varieties PR114 and Pusa44 were developed. Out these, based on agronomic acceptability, 318 used developing hybrids to assess effect introgressions heterozygous state. These their recurrent parents, possessing fertility restoration ability abortive (WA)...
Three rust diseases namely; stem caused by Puccinia graminis f. sp. tritici (Pgt), leaf triticina (Pt), and stripe striiformis (Pst), are the most common fungal of wheat (Triticum aestivum L.) cause significant yield losses worldwide including Australia. Recently characterized resistance genes Yr51 Yr57 effective against pre- post-2002 Pst pathotypes in Similarly, Sr22, Sr26, Sr50 Pgt pathotype TTKSK (Ug99) its derivatives addition to commercially important Australian pathotypes....
Optimizing wheat height to maximize yield has been an important aspect which is evident from a successful example of green revolution. Dwarfing genes (Rht) are known for gains due lodging resistance and partitioning assimilates into ear. The available commercially exploited sources dwarfism in Indian spring Rht1 Rht2 inspite availability over 20 dwarfing genes. Rht8 Gibberellic acid sensitive gene another reduced some Mediterranean countries. Two F2 populations segregating with each...
Effects of putrescine (Put) on responses wheat (Triticum aestivum) seedlings or detached tillers at mid-milky stage to high temperature (HT) stress were investigated. The heat tolerant cv. PBW 343 exhibited higher content antioxidants and activities antioxidative enzymes, while lower lipid peroxides as compared the heat-sensitive HD 2329. HT elevated peroxidase (POX) superoxide dismutase (SOD) activities, diamine oxidase (DAO) polyamine (PAO) reduced in roots, shoots developing grains....
Background Stripe rust, leaf tan spot, and Karnal bunt are economically significant diseases impacting wheat production. The objectives of this study were to identify quantitative trait loci for resistance these in a recombinant inbred line (RIL) from cross HD29/WH542, evaluate the evidence presence on chromosome region conferring multiple disease resistance. Methodology/Principal Findings RIL population was evaluated four genotyped with DNA markers. Multi-trait (MT) analysis revealed...
Nitrogen is an essential element required for plant growth and development.However, over-use of nitrogen fertilizer not only costly but also environmentally unsafe.Therefore, identification genotypes possessing higher use efficiency (NUE) at sub-optimal dose the key challenge.In this study, effect on activities assimilatory enzymes, total soluble proteins amino acids was studied in wheat diverse physiology (viz., GLU 1101, 1356, 2001, 700, PH132-4836, PH132-4840).Nitrogen applied recommended...
Content of polyamines and activities antioxidative enzymes in response to stripe rust disease caused by Puccinia striiformis have been studied two wheat (Triticum aestivum L.) cultivars PBW 343 (resistant) HD 2329 (susceptible). Various infection stages ranging from traces 100 % were collected. Infection leads stimulation peroxidase (POD), superoxide dismutase (SOD), catalase, diamine oxidase polyamine along with increase putrescine, spermidine spermine content while ascorbate, tocopherol...
