Sub-Saharan West Africa is a vulnerable region where better quantification and understanding of the impact climate change on crop yields urgently needed. Here, we have applied process-based model SARRA-H calibrated validated over multi-year field trials surveys at eight contrasting sites in terms agricultural practices Senegal, Mali, Burkina Faso Niger. The gives reasonable correlation with observed sorghum millet under range cultivars traditional management practices. We to more than 7000...
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...
• Background and Aims There are three reasons for the increasing demand crop models that build plant on basis of architectural principles organogenetic processes: (1) realistic concepts developing new crops need to be guided by such models; (2) there is an interest in phenotypic plasticity, based variable architecture morphology; (3) engineering mechanized cropping systems requires information architecture. The functional–structural model GREENLAB was recently presented simulates...
Elucidating the genetic control of rooting behavior under water-deficit stress is essential to breed climate-robust rice (Oryza sativa) cultivars. Using a diverse panel 274 indica genotypes grown and conditions during vegetative growth, we phenotyped 35 traits, mostly related root morphology anatomy, involving 45,000 root-scanning images nearly 25,000 cross sections from root-shoot junction. The phenotypic plasticity these traits was quantified as relative change in trait value compared with...
Because of rapid advances in functional genomics there is an increasing demand for models simulating complex traits, such as the physiological and environmental controls plant morphology. This paper describes, validates explores behaviour structural–functional model EcoMeristem, developed cereals context Generation Challenge Program (GCP; CGIAR). EcoMeristem constructs on basis organogenetic body plan, driven by intrinsic (genetic) behavioural norms meristems. These consist...
Background and Aims Tillering has a significant effect on canopy development and, hence, resource capture, crop growth grain yield in sorghum.However, the physiological basis of tillering its regulation by environmental effects are not fully understood.The objective this study was to understand quantify sorghum using carbohydrate supply-demand framework.† Methods A series five experiments with wide range radiation temperature conditions conducted details responses single representative...
Ferrous iron (Fe) and zinc (Zn) at high concentration in the soil cause heavy metal toxicity greatly affect rice yield quality. To improve production, understanding genetic molecular resistance mechanisms to excess Fe Zn is essential. Genome-wide association study (GWAS) an effective way identify loci favorable alleles governing toxicty as well dissect relationship between them a genetically diverse population. A total of 29 31 putative QTL affecting shoot height (SH), root length (RL),...
Grain appearance quality and milling are the main determinants of market value rice. Breeding for improved grain is a major objective rice breeding worldwide. Identification genes/QTL controlling traits prerequisite increasing efficiency through marker-assisted selection. Here, we reported genome-wide association study in indica to identify QTL associated with 10 related traits, including length, width, length width ratio, thickness, thousand weight, degree endosperm chalkiness, percentage...
Early vigour of rice, defined as seedling capacity to accumulate shoot dry weight (SDW) rapidly, is a complex trait. It depends on genotype propensity assimilate, store, and/or use non-structural carbohydrates (NSC) for producing large numerous leaves, involving physiological trade-offs in the expression component traits and, possibly, and genetic linkages. This study explores plant-model-assisted phenotyping approach dissect architecture rice early vigour, applying Genome Wide Association...
Number of spikelets per panicle (NSP) is a key trait to increase yield potential in rice (O. sativa). The architecture the inflorescence which mainly determined by length and number primary (PBL PBN) secondary (SBL SBN) branches can influence NSP. Although several genes controlling NSP have been identified, there little evidence (i) genetic control different environments (ii) presence stable associations with across environments. This study combines image phenotyping 225 accessions belonging...
This study aimed to understand the physiological basis of rice photosynthetic response C source-sink imbalances, focusing on dynamics parameter triose phosphate utilization (TPU). Here, (Oriza sativa L.) indica cultivar IR64 were grown in controlled environment chambers under current ambient CO2 concentration until heading, and thereafter two treatments (400 800 μmol mol-1) compared presence absence a panicle-pruning treatment modifying sink. At 2 weeks after parameters derived from curves,...
