Abstract Grain yield is a major goal for the improvement of durum wheat, particularly in drought-prone areas. In this study, genetic basis grain (GY), heading date (HD), and plant height (PH) was investigated wheat population 249 recombinant inbred lines evaluated 16 environments (10 rainfed 6 irrigated) characterized by broad range water availability GY (from 5.6 to 58.8 q ha−1). Among quantitative trait loci (QTL) that affected GY, two QTL on chromosomes 2BL 3BS showed significant effects...
Functional markers are needed for key genes involved in drought tolerance to improve selection crop yield under moisture stress conditions. The objectives of this study were (i) characterize five candidate genes, namely dehydration responsive element binding 1A ( DREB1A ), enhanced response abscisic acid ERA1‐B and ERA1‐D fructan 1‐exohydrolase 1‐FEH‐A 1‐FEH‐B wheat Triticum aestivum L.) nucleotide haplotype diversity, Tajima's D value, linkage disequilibrium (LD) (ii) associate within‐gene...
Two hundred sixteen barley ( Hordeum vulgare L.) cultivars were selected to represent the diversity and history of European spring two‐row breeding search for alleles controlling agronomic traits by association genetics. The germplasm was genotyped with 7864 gene‐based single nucleotide polymorphism markers corresponding field trial trait data relating growth straw strength obtained at multiple sites. Analysis marker statistical population genetics approaches revealed two important trends in...
SUMMARY The allelic composition at five glutenin loci was assessed by one-dimensional sodium dodecyl sulphate polyacrylamide gel electrophoresis (1D SDS–PAGE) on a set of 155 landraces (from 21 Mediterranean countries) and 18 representative modern varieties. Gluten strength determined SDS-sedimentation samples grown under rainfed conditions during 3 years in north-eastern Spain. One hundred fourteen alleles/banding patterns were identified (25 Glu-1 89 Glu-2 / Glu-3 loci); 0·85 them very low...
Abstract This study was carried out in order to determine the effect of seed size on growth and yield durum wheat. Four field experiments, composed six wheat ( Triticum turgidum L. var. ) varieties three seeding sizes were conducted north‐east Spain 2000 2001 randomized complete block designs. The seedlings dramatically affected by size. Large seeds produced greater plot stands, but plants had fewer tillers, leaves spikes less green area dry weight than plots from small seeds. Grain 16 %...
Abstract Breeding for specific or wide adaptation would be more cost‐efficient if preliminary indications on genotype adaptive responses could provided by easily‐detectable morphophysiological molecular characteristics. We investigated the consistency among parameters, traits and SSR markers in estimating structuring genetic diversity 24 durum wheat genotypes. Additive main effects multiplicative interaction parameters were estimated across 14 Algerian locations belonging to a low‐...
Phenology is critical in simulating crop production and hydrology must be sufficiently robust to respond varying environments, soils, management practices. Phenological algorithms typically focus on the air temperature response function rarely quantify phenological responses water deficits, particularly for versions of Environmental Policy Integrated Climate model (EPIC)‐based plant growth component used many agroecosystem models. Three EPIC‐based components (Soil Water Assessment Tool...
ABSTRACT Uniquely naming wheat ( Triticum aestivum L.) plant parts is useful for communicating development research and the effects of environmental stresses on normal development. Over past 30+ years, several systems have been proposed shoot, leaf, spike, spikelet, floret, caryopsis structures. While these work very well in most field situations, problems emerged that can lead to confusion uniquely all possible tillers leaves. This unnecessary leads errors communication be avoided. paper...
