Sorghum is a food and feed cereal crop adapted to heat drought staple for 500 million of the world's poorest people. Its small diploid genome phenotypic diversity make it an ideal C4 grass model as complement C3 rice. Here we present high coverage (16–45 × ) resequenced genomes 44 sorghum lines representing primary gene pool spanning dimensions geographic origin, end-use taxonomic group. We also report first S. propinquum, identifying 8 M high-quality SNPs, 1.9 indels specific loss gain...
Sorghum is an important source of food, feed, and biofuel, especially in the semi-arid tropics because this cereal well adapted to harsh, drought-prone environments.Post-flowering drought adaptation sorghum associated with stay-green phenotype.Alleles that contribute complex trait have been mapped four major QTL, Stg1-Stg4, using a population derived from BT3642 RT37000.Near-isogenic RT37000 lines containing DNA spanning one or more QTL were constructed.The size location regions each NIL...
Stay-green sorghum plants exhibit greener leaves and stems during the grain-filling period under water-limited conditions compared with their senescent counterparts, resulting in increased grain yield, mass, lodging resistance. has been mapped to a number of key chromosomal regions, including Stg1, Stg2, Stg3, Stg4, but functions these individual quantitative trait loci (QTLs) remain unclear. The objective this study was show how positive effects Stg QTLs on yield drought can be explained as...
Summary Stay‐green is an integrated drought adaptation trait characterized by a distinct green leaf phenotype during grain filling under terminal drought. We used sorghum ( Sorghum bicolor ), repository of mechanisms, to elucidate the physiological and genetic mechanisms underpinning stay‐green. Near‐isogenic lines (cv RT x7000) were in series field managed‐environment trials (seven experiments 14 environments) determine influence four individual stay‐green Stg1–4 ) quantitative loci QTL s)...
The yield of cereal crops such as sorghum ( Sorghum bicolor L. Moench) depends on the distribution crop-heads in varying branching arrangements. Therefore, counting head number per unit area is critical for plant breeders to correlate with genotypic variation a specific breeding field. However, measuring phenotypic traits manually an extremely labor-intensive process and suffers from low efficiency human errors. Moreover, almost infeasible large-scale plantations or experiments. Machine...
Sorghum genome mapping based on DNA markers began in the early 1990s and numerous genetic linkage maps of sorghum have been published last decade, initially RFLP with more recent including AFLPs SSRs very recently, Diversity Array Technology (DArT) markers. It is essential to integrate rapidly growing body data produced through DArT multiple for generated other marker technologies. Here, we report colinearity six independent component integration these into a single reference resource that...
ABSTRACT The stay‐green drought adaptation mechanism has been widely promoted as a way of improving grain yield and lodging resistance in sorghum [ Sorghum bicolor (L.) Moench] result the subject many physiological genetic studies. relevance these studies to elite hybrids is not clear given that they sample limited number environments were conducted using inbred lines or relatively small numbers experimental F 1 hybrids. In this study we investigated relationship between data from breeding...
Climatic variability in dryland production environments (E) generates variable yield and crop risks. Optimal combinations of genotype (G) management (M) depend strongly on E thus vary among sites seasons. Traditional improvement seeks broadly adapted genotypes to give best average performance under a standard regime across the entire region, with some subsequent manipulation regionally response local environmental conditions. This process does not search full spectrum potential G × M forming...
Abstract Background The sequential nature of gel-based marker systems entails low throughput and high costs per assay. Commonly used such as SSR SNP are also dependent on sequence information. These limitations result in cost data point significantly limit the capacity breeding programs to obtain sufficient return investment justify routine use marker-assisted for many traits particularly quantitative traits. Diversity Arrays Technology (DArT™) is a effective hybridisation-based technology...
Genetic improvement in sorghum breeding programs requires the assessment of adaptation traits small-plot trials across multiple environments. Many these phenotypic assessments are made by manual measurement or visual scoring, both which time consuming and expensive. This limits trial size potential for genetic gain. In addition, methods typically restricted to point estimates particular traits, such as leaf senescence flowering do not capture dynamic nature crop growth. water-limited...
A flexible and user-friendly spatial method called SpATS performed comparably to more elaborate trial-specific models in a series of sorghum breeding trials. Adjustment for trends plant field trials is essential efficient evaluation selection genotypes. Current mixed model methods analysis are based on multi-step modelling process where global local fitted after trying several candidate models. This paper reports the application novel that accounts all types continuous variation single step...
Summary Grain size is a key yield component of cereal crops and major quality attribute. It determined by genotype’s genetic potential its capacity to fill the grains. This study aims dissect architecture grain in sorghum. An integrated genome‐wide association (GWAS) was conducted using diversity panel ( n = 837) BC‐NAM population 1421). To isolate effects associated with size, rather than grains, treatment removing half panicle imposed during flowering. Extensive highly heritable variation...
