Abstract Stomatal conductance is central for the trades‐off between hydraulics and photosynthesis. We aimed at deciphering its genetic control that of responses to evaporative demand water deficit, a nearly impossible task with gas exchanges measurements. Whole‐plant stomatal was estimated via inversion Penman–Monteith equation from data transpiration plant architecture collected in phenotyping platform. have analysed jointly 4 experiments contrasting environmental conditions imposed panel...
Abstract While numerous wheat phenology prediction models are available, most of them constrained to using variety-dependent coefficients. The overarching objective this study was calibrate a gene-based model predict heading date that allows breeders select specific gene combinations would head within the optimal window for given environment independently varietal genetic background. A dataset with total 49 Argentine cultivars and two recombinant inbred lines chosen cover wide range allelic...
Maize kernel weight (KW) is associated with the duration of grain-filling period (GFD) and rate biomass accumulation (KGR). It also related to dynamics water hence physiologically linked maximum content (MWC), desiccation (KDR), moisture concentration at physiological maturity (MCPM). This work proposed that principles phenotypic plasticity can help consolidated understanding environmental modulation genetic control these traits. For purpose, a maize population 245 recombinant inbred lines...
Individual kernel weight is an important trait for maize yield determination. We have identified genomic regions controlling this by using the B73xMo17 population; however, effect of genetic background on control complex and its physiological components not yet known. The objective study was to understand how affected our previous results. Two nested stable recombinant inbred line populations (N209xMo17 R18xMo17) were designed purpose. A total 408 lines genotyped phenotyped at two...
Multi-genotype canopies are frequent in phenotyping experiments and of increasing interest agriculture. Radiation interception efficiency (RIE) radiation use (RUE) have low heritabilities such canopies. We propose a revised Monteith equation that identifies environmental genetic components RIE RUE. An term, component RIE, characterizes the effect presence or absence neighbours on light interception. The ability given plant to compete with its is then identified, which accounts for...
This study focuses on the impact of genetic improvement seed yield plasticity in soybean (Glycine max L.) high-yielding environments (between 4000 kg ha-1 and 7000 ha-1) Central Argentina. The association between its was analysed with (i) a historical collection 148 genotypes released to market 1980 2013 (ii) 165 currently available commercial genotypes. breeding programmes Argentina reveals higher progress lowest (1.7% year-1) rather than highest yielding (0.9% year-1). At same time, has...
Abstract Abstract. Accurate prediction of phenology is the most critical aspect for development models aimed at estimating seed yield, particularly in species that exhibit variable sensitivity to environmental factors throughout cycle and among genotypes. With this purpose, we evaluated 34 soybean varieties field experiments located Argentina, Uruguay Paraguay. Experiments covered a broad range maturity group (MG)s (2.2–6.8), sowing dates (SDs) (from spring summer) latitude (24.9–35.6 °S),...
Abstract Plant aquaporins are involved in numerous physiological processes, such as cellular homeostasis, tissue hydraulics, transpiration, and nutrient supply, key players of the response to environmental cues. While varying expression patterns aquaporin genes have been described across organs, developmental stages, stress conditions, underlying regulation mechanisms remain elusive. Hence, this work aimed shed light on variability 4 plasma membrane intrinsic protein (PIP) maize (Zea mays)...
ABSTRACT Individual kernel weight (KW) is largely genetically determined, and its variability achieved through different combinations of rate duration growth. Genetic for grain‐filling patterns has been observed among inbred lines commercial hybrids, there current interest on dissecting genetic basis. However, suitable grain filling phenotyping protocols are still to be such as the value study traits at or hybrid levels. The objective our was evaluate correlation between parental line...
Abstract In wheat and barley, grain yield is strongly affected by waterlogging, especially during the period immediately previous to anthesis. Although waterlogging reduces mainly reductions in number, mean weight (MGW) also frequently reduced. The aim of this work was determine whether increases source‐sink ratio produces smaller MGW due barley. Two experiments were carried out combining a condition 20 days pre‐anthesis, two soil N conditions at sowing manipulations grain‐filling (untrimmed...
Based on case studies, we discuss the extent to which genome-wide association studies (GWAS) are affected by outlier plants, i.e. those deviating from expected distribution a multi-criteria basis. Using raw dataset consisting of daily measurements leaf area, biomass, and plant height for thousands tested three different cleaning methods their effects genetic analyses. No-cleaning resulted in highest number dubious quantitative trait loci, especially at loci with highly unbalanced allelic...
Abstract Modification of source–sink ratios in tropical maize through detasseling is an ancestral agronomical practice used for increasing yields under stressful conditions. However, the mechanisms behind such effect are not well understood given difficulties to determine physiological processes as photosynthesis and whole‐plant transpiration field. We have tested potential ability kernel δ 18 O assess differences grain yield ( GY ) changes plant caused by modification water availability...
