Rice is a crop prone to drought stress in upland and rainfed lowland ecosystems. A deep root system recognized as the best avoidance mechanism. Genome-wide association mapping offers higher resolution for locating quantitative trait loci (QTLs) than QTL biparental populations. We performed an study traits using panel of 167 japonica accessions, mostly tropical origin. The was genotyped at average density one marker per 22.5 kb genotyping by sequencing technology. linkage disequilibrium high...
During the last 10 years, a large number of quantitative trait loci (QTLs) controlling rice root morphological parameters have been detected in several mapping populations by teams interested improving drought resistance rice. Compiling these data could be extremely helpful identifying candidate genes positioning consensus QTLs with more precision through meta-QTL analysis. We extracted information from 24 published papers on 29 including number, maximum length, thickness, root/shoot ratio,...
An interspecific Gossypium hirsutum x barbadense backcross population of 75 BC1 plants was evaluated for 1014 markers. The map consists 888 loci, including 465 AFLPs, 229 SSRs, 192 RFLPs, and 2 morphological markers, ordered in 37 linkage groups that represent most if not all the 26 chromosomes, altogether spanning 4400 cM. Loci were evenly distributed over groups, 18 long had a single dense region. This paper proposes partially revised list 13 pairs homoeologous A/D chromosomes 2n = 4x 52...
Abstract The objective of this paper is to review the possibilities for using allelopathy improve overall crop competitive ability against weeds, rice, Oryza sativa , as an example. Laboratory, greenhouse and field screenings weed suppression in rice have been made allelopathic germplasm has identified laboratory screening. Field experiments revealed that accounted 34% rice. For strongly cultivars, was dominant factor determining ability. Based on results screenings, recombinant inbred line...
One-fifth of irrigated agriculture is negatively affected by high soil salinity. The expected population growth, over 9 billion 2050, enhances the pressure for agricultural production in marginal saline lands. Rice (Oryza sativa L.), staple food more than half world's population, most salt-sensitive cereal. need salt-tolerant rice varieties able to cope with several other stress conditions obviously puts a lot on breeders who must better comprehend physiology and genetic control salt...
Cotton fiber properties are essential predictors of yarn performance. The suite quality traits that collectively affect the utility for textile industry include length, strength, fineness and color. These have been shown to be moderately highly heritable. In an attempt overcome limitations conventional breeding we undertook a marker-assisted selection program aimed at introgressing QTLs from Gossypium barbadense L. into G. hirsutum We describe QTL analysis 11 measured on three phenotypic...
Theobroma cacao L., is a tree originated from the tropical rainforest of South America. It one major cash crops for many countries. T. mainly produced on smallholdings, providing resources 14 million farmers. Disease resistance and quality improvement are two important challenges all actors cocoa chocolate production. seriously affected by pests fungal diseases, responsible more than 40% yield losses improvement, nutritional organoleptic, also consumers.

A quantitative trait locus (QTL) analysis designed for a multi-parent population was carried out and tested in oil palm (Elaeis guineensis Jacq.), which is diploid cross-fertilising perennial species. new extension of the MCQTL package especially crosses between heterozygous parents. The algorithm, now available any allogamous species, used to perform compare two types QTL search small size families, within-family across-family analysis, using data from 2 x complete factorial mating...
Summary Salt stress is a complex physiological trait affecting plants by limiting growth and productivity. Rice, one of the most important food crops, rated as salt‐sensitive. High‐throughput screening methods are required to exploit novel sources genetic variation in rice further improve salinity tolerance breeding programmes. To search for genotypic differences related salt stress, we genotyped 392 accessions Eco TILLING . We targeted five key salt‐related genes involved mechanisms such N...
Abstract Background Polyploidy can result in genetic bottlenecks, especially for species of monophyletic origin. Cultivated peanut is an allotetraploid harbouring limited diversity, likely resulting from the combined effects its single origin and domestication. Peanut wild relatives represent important source novel alleles that could be used to broaden basis cultigen. Using advanced backcross population developed with a synthetic amphidiploid as donor alleles, under two water regimes, we...
Genomic selection (GS) is a promising strategy for enhancing genetic gain. We investigated the accuracy of genomic estimated breeding values (GEBV) in four inter-related synthetic populations that underwent several cycles recurrent an upland rice-breeding program. A total 343 S2:4 lines extracted from those were phenotyped flowering time, plant height, grain yield and panicle weight, genotyped with average density one marker per 44.8 kb. The relative effect linkage disequilibrium (LD) minor...
Drought is the major abiotic stress limiting rice (Oryza sativa) production and yield stability in rainfed lowland upland ecosystems. Root systems play an important role drought resistance. Incorporation of root selection criteria resistance improvement difficult due to lack reliable efficient screening techniques. Using a wax-petrolatum layer system simulated compacted soil layers, traits were evaluated doubled haploid (DH) population derived from cross between 'IR64' 'Azucena'. Twelve...
