Previous studies with 95 bread wheat doubled haploid lines (DHLs) from the cross Chinese Spring (CS)×SQ1 trialled over 24 year×treatment×locations identified major yield quantitative trait loci (QTLs) in homoeologous locations on 7AL and 7BL, expressed mainly under stressed non-stressed conditions, respectively. SQ1 CS contributed alleles increasing The component most strongly associated these QTLs was grains per ear. Additional results which focus QTL are presented here. Trials monitoring...
A difficulty in identifying traits that help crop plants maintain their yield under droughted conditions is distinguishing between those contribute to stability drought and do not affect yield. With the development of molecular markers for many crops it now possible identify major quantitative trait loci (QTL) regulating specific responses. By comparing coincidence such QTL test much more precisely than before whether a particular constitutive or adaptive response stress likely be...

In this study, the seedlings of two wheat cultivars were used: drought-resistant Chinese Spring (CS) and drought-susceptible (SQ1). Seedlings subjected to osmotic stress in order assess differences response drought between resistant susceptible genotype. The aim experiment was evaluate changes physiological biochemical characteristics establish optimum level which resistance genotypes could be revealed. Plants by supplementing root medium with three concentrations PEG 6000. grown for 21 days...
The usual method to locate and compare loci regulating quantitative traits (QTLs) requires a segregating population of plants with each one genotyped molecular markers. However, from such populations can also be grouped according phenotypic expression trait tested for differences in allele frequency between the bulks: bulk segregant analysis (BSA). same probes used making genetic map (e.g. isozyme, RFLP, RAPD, etc) BSA. A marker showing polymorphism parents which is closely-linked major QTL...
Testing possible associations between physiological and biochemical traits by comparing plant phenotypes looking for correlations them is unreliable. The development of molecular marker technologies offers powerful alternative methods to examine the relationships traits. This review describes genetical required analyse that are inherited in a quantitative manner using trait locus (QTL) analysis. regulation carbohydrate metabolism chosen as an example how QTL analysis can be used identify key...
Relatively little is known of the genetic control chlorophyll fluorescence (CF) and pigment traits important in determining efficiency photosynthesis wheat its association with biomass productivity. A doubled haploid population 94 lines from cross Chinese Spring × SQ1 was trialled under optimum glasshouse conditions for 4 years to identify quantitative trait loci (QTL) CF including, first time wheat, JIP-test parameters per excited section (CSm): ABS/CSm, DIo/CSm, TRo/CSm, RC/CSm ETo/CSm,...
In this paper we tested the hypothesis that leaf growth reduction of salt-stressed maize is regulated by abscisic acid (ABA) concentrations in growing zone leaf. Leaf elongation rate (LER) (Zea mays L.) was rapidly inhibited salinity (80 mM NaCl), and (+)-ABA concentration increased significantly Upon removal salinity, ABA decreased LER to control levels. Four genotypes differing their responses were compared over a range concentrations. highly correlated with inhibition for all four...
Abstract. Droopy mutant of potato ( Solanum tubero‐sum L., group Pliureja ) wilts because excessive stomatal opening (Waggoner & Simmonds, 1966). Progeny the cross between clones C.P.C. 4461 and 4463 showed characteristics similar to those original droopy potato. These plants wilted at high vapour pressure deficit their conductances in light dark were higher than normal plants. Conductances reduced by applied abscisic acid (ABA), but stomata remained partially open even when guard cells...
A technique for studying variation in the accumulation of abscisic acid (ABA) response to drought stress is described. Two experiments, each testing 26 spring wheat genotypes, were carried out using pot grown plants controlled environment cabinets with nutrient solution culture, though results only one experiment are described detail. Plants subjected water by withholding as fifth or sixth leaf on main stem was emerging. stressed genotype harvested 5 and 7 days after treatment commenced...
Summary Selection for high-(H) and low-(L) drought-induced abscisic acid (ABA) accumulation in spring wheat was made from a cross between parents which contrasted the character. By F 5 generation H L selections were homozygous ABA accumulation, differed classes by 80%. The evaluated field experiments amount of available water varied. In one experiment, plots automatically sheltered rain, outyielded an average 0·36 t/ha both when fully irrigated withheld anthesis maturity. extra grain yield...
Abstract. Twenty cultivars of spring wheat were examined for variation in abscisic acid (ABA) accumulation following partial dehydration excised leaves. A 3‐fold range ABA concentration was obtained. cross between two which differed drought‐induced used to study the heritability and develop lines differing their capacity accumulate ABA. Broad sense 0–32 F 2 3 generations 0–70 4 generations. Apparent homozygosity achieved several selections at . The possible significance drought resistance...
Genetic analyses and association mapping were performed on a winter wheat core collection of 96 accessions sampled from variety geographic origins. Twenty-four agronomic traits evaluated over 3 years under fully irrigated, rainfed drought treatments. Grain yield was the most sensitive trait to water deficit highly correlated with above-ground biomass per plant number kernels m2. The germplasm structured into four subpopulations. 46 SSR loci distributed throughout genome analyzed using...
Drought tolerance is one of the most important but complex traits crops.We looked for quantitative trait loci (QTLs) that affect drought in maize.Two maize inbreds and their advanced lines were evaluated drought-related traits.A genetic linkage map developed using RFLP markers was used to identify QTLs associated with traits.Twenty-two detected, a minimum maximum nine single-QTL detected sugar concentration accounting about 52.2% phenotypic variation on chromosome 6.A also identified each...
Drought is one of the major factors limiting wheat yield in many developing countries worldwide. Parameters chlorophyll a fluorescence kinetics under drought stress conditions have been used to characterize dehydration tolerance wheat. In present study, set 94 doubled haploid lines obtained from Chinese Spring × SQ1 (CSDH), mapped with 450 markers, was evaluated for (grain dry weight/main stem ear), number grains/main ear (NG) and parameters (FC) moderate severe stress, compared results...
