Genomic regions responsible for accumulation of grain iron concentration (Fe), zinc (Zn), protein content (PC) and thousand kernel weight (TKW) were investigated in 286 recombinant inbred lines (RILs) derived from a cross between an old Indian wheat variety WH542 synthetic derivative (Triticum dicoccon PI94624/Aegilops squarrosa [409]//BCN). RILs grown six environments evaluated Fe, Zn, PC, TKW. The population showed the continuous distribution all four traits, that pooled Fe PC was near...
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 Malnutrition due to micronutrients and protein deficiency is recognized among the major global health issues. Genetic biofortification of wheat a cost-effective sustainable strategy mitigate micronutrient malnutrition. Genomic regions governing grain zinc concentration (GZnC), iron (GFeC), content (GPC), test weight (TW), thousand kernel (TKW) were investigated in set 184 diverse bread genotypes through genome-wide association study (GWAS). The GWAS panel was genotyped using...
Drought is considered as a significant stress that hampers growth, development well productivity of wheat crop around the globe. The present investigation was performed to determine changes induced by drought on morpho-physiology, antioxidative system, metabolism and yield parameters in crop. study also focussed evaluating effect zinc-chitosan-salicylic acid (ZCS) nanoparticles alleviating physiological biochemical alterations overcoming losses caused drought. provided during vegetative...
Genome wide association study (GWAS) was conducted for 14 agronomic traits in wheat following widely used single locus trait (SLST) approach, and two recent approaches viz. multi mixed model (MLMM), multi-trait (MTMM). Association panel consisted of 230 diverse Indian bread cultivars (released during 1910-2006 commercial cultivation different agro-climatic regions India). Three years phenotypic data genotyping 250 SSR markers (distributed across all the 21 chromosomes) utilized GWAS. Using...
Finger millet [ Eleusine coracana (L.) Gaertn.] is grown mainly by subsistence farmers in arid and semiarid regions of the world. To broaden its genetic base to boost production, it paramount importance characterize genotype diverse gene pool this important food nutritional security crop. However, as a result nonavailability genome sequence finger millet, progress could not be made realizing molecular basis unique qualities In present investigation, attempts have been genetically collection...
Micronutrient and protein malnutrition is recognized among the major global health issues. Genetic biofortification a cost-effective sustainable strategy to tackle malnutrition. Genomic regions governing grain iron concentration (GFeC), zinc (GZnC), content (GPC), thousand kernel weight (TKW) were investigated in set of 163 recombinant inbred lines (RILs) derived from cross between cultivated wheat variety WH542 synthetic derivative ( Triticum dicoccon PI94624/ Aegilops tauschii [409]//BCN)....
Leaf rust (Puccinia triticina Eriks.) is a fungal disease of wheat (Triticum spp.), which causes considerable yield loss. Adult plant resistance (APR) one the most sustainable approaches to control leaf rust. In this study, field-testing was carried out across ten different locations, followed by molecular screening, detect presence APR genes, Lr34+, Lr46+, Lr67+ and Lr68 in Indian germplasm. field 190 accessions were selected from 6,319 based on tip necrosis (LTN), severity average...
Six generations namely, P1, P2, F2, F3, BC1s and BC2s (2006-07) F4, BC1ss BC2ss (2007-08) developed from four parental genotypes viz. DBW 14 (heat tolerant), NP 846 drought WH 147 Raj 4014 susceptible for late sown). All the six crosses were evaluated during Rabi 2006-07 2007-08 in a compact family block design with three replications on two sowing dates. Heat susceptibility index values revealed reduction grain yield both years all of crosses. Significant estimates correlation days to...
Teosinte is the closest wild ancestor of maize and used as a valuable resource for taxonomical, evolutionary genetic architectural studies maize. also repository numerous diverse alleles complex traits, including nutritional value stress adaptation. Accessions teosintes, inbred lines coix were investigated kernel protein its association with DNA markers. The proposed investigation assumed that accessions had different genic/allelic content consequently expression profile than modern because...
Wheat (Triticum aestivum L.), a staple food crop is of great commercial importance. Its production restricted due to various abiotic stresses. There are indications that the wheat consistently limited by terminal heat stress. Here, performance forty genotypes was undertaken for assessment direct selection parameters (variability, heritability and genetic advance) their relation with tolerance. The plants were sown in late planting (first fortnight December) expose them Observations recorded...
The present investigation was carried out with 32 diverse genotypes of bread wheat in completely randomized block design 3 replications at Norman E. Borlaug Crop Research Centre, G.B. Pant University agriculture & Technology Pantnagar for screening the genetic diversity yield and physiological traits under normal sown condition. observations were recorded on 16 agronomic traits. statistical analysis divergence done using Mahalanobis-D2 statistics clustering Tocher method. On basis analysis,...
Abstract Genetic improvement along with widened crop base necessitates for the detailed understanding of genetic diversity and population structure in wheat. The present investigation reports discovery a total 182 alleles by assaying 52 simple sequence repeats (SSRs) on 40 genotypes bread Unweighted neighbour-joining method grouped these into two main clusters. Highly heat tolerant intermediate cultivars were same cluster, whereas remaining genotypes, particularly sensitive ones, assigned...
A set of 306 recombinant inbred lines (RILs) along with the two parents and hitherto popular wheat variety in India, PBW 343, were evaluated three environments over years for grain iron (Fe) zinc (Zn) concentration. Considerable genetic variation both concentration exists. The environment effect was most important source Fe Zn concentration, explaining 37.42% 57.78% total sum squares respectively. Genotype-environment interaction (G x E) accounted 29.46% 23.24% squares, magnitude G E...
Polyphenol oxidase (PPO) activity is a primary cause of the development unattractive dark brown discoloration wheat-based end products. The present study aims to evaluate set 41 diverse wheat genotypes grown at three different locations in India for grain phenol color reaction, PPO and molecular marker-based characterization alleles genes. Relationships among these parameters were analyzed along with effects on dough chapati time intervals. mean ranged from 7.42 27.57 min−1 g−1 10−3 it...
