With high productivity and stress tolerance, numerous grass genera of the Andropogoneae have emerged as candidates for bioenergy production. To optimize these candidates, research examining genetic architecture yield, carbon partitioning, composition is required to advance breeding objectives. Significant progress has been made developing genomic resources Andropogoneae, advances in comparative computational genomics enabled basis photosynthesis, composition, sink strength. provide a pivotal...
Grain yield and its primary determinants, grain number weight, are important traits in cereal crops that have been well studied; however, the genetic basis of interactions between these remain poorly understood. Characterization per panicle (YPP), (GNP), 1000‐grain weight (TGW) sorghum [ Sorghum bicolor (L.) Moench], a hardy C 4 with genome size ∼730 Mb, was implemented diversity panel containing 390 accessions. These accessions were genotyped to obtain 268,830 single‐nucleotide...
Sorghum [Sorghum bicolor (L.) Moench] is an important cereal crop for dryland areas in the United States and small-holder farmers Africa. Natural variation of sorghum grain composition (protein, fat, starch) between accessions can be used improvement, but genetic controls are still unresolved. The goals this study were to quantify natural identify single-nucleotide polymorphisms (SNPs) associated with concentrations. In study, we quantified protein, starch a global diversity panel using...
Association mapping panels represent foundational resources for understanding the genetic basis of phenotypic diversity and serve to advance plant breeding by exploring variation across diverse accessions. We report whole-genome sequencing (WGS) 400 sorghum (Sorghum bicolor (L.)

Coordinated association and linkage mapping identified 25 grain quality QTLs in multiple environments, fine of the Wx locus supports use high-density genetic markers mapping. There is a wide range end-use products made from cereal grains, these often demand different characteristics. Fortunately, crop species including sorghum [Sorghum bicolor (L.) Moench] contain high phenotypic variation for traits influencing quality. Identifying variants underlying this allows plant breeders to develop...
Seedling establishment and seed nutritional quality require the sequestration of sufficient element nutrients. The identification genes alleles that modify content in grains cereals, including sorghum (Sorghum bicolor), is fundamental to developing breeding selection methods aimed at increasing bioavailable improving crop growth. We have developed a high-throughput work flow for simultaneous measurement multiple elements seeds. measured levels genotyped Sorghum Association Panel,...
Abstract Reducing generation time is critical to achieving the goals of genetic gain in important crops like wheat ( Triticum aestivum ). Speed breeding (SB) has been shown considerably reduce times crop plants. Unlike spring cultivars, winter varieties require typically 6–9 weeks cold treatment, called vernalization, for flowering which extends development improved cultivars. Here, we optimized SB method using a set 48 diverse soft red (SRWW) cultivars by testing vernalization duration,...
Abstract Sorghum bicolor, a photosynthetically efficient C4 grass, represents an important source of grain, forage, fermentable sugars, and cellulosic fibers that can be utilized in myriad applications ranging from bioenergy to bioindustrial feedstocks. Sorghum’s fixation carbon per unit time area input has led its classification as preferred biomass crop highlighted by designation advanced biofuel the U.S. Department Energy. Due extensive genetic diversity worldwide colonization, sorghum...
Abstract Tremendous progress has been made in variety development and host plant resistance to mitigate the impact of Fusarium head blight (FHB) since disease manifested southeastern United States early 2000s. Much this improvement was possible through establishment recurring support from US Wheat & Barley Scab Initiative (USWBSI). Since its inception 1997, USWBSI enabled land‐grant institutions make advances reducing annual threat devastating FHB epidemics. A coordinated field...
ABSTRACT Phenotypic plasticity is the property of a genotype to produce different phenotypes under environmental conditions. Understanding genetic and factors behind phenotypic helps answer some longstanding biology questions improve phenotype prediction. In this study, we investigated flowering time plant height with set diverse sorghum lines evaluated across 14 natural field environments. An index was identified quantitatively connect Reaction norms were then obtained indices for...
This exploratory study expected crop management and climatic factors to significantly influence the nutrient composition amino acid digestibility of tannin-free sorghum grain determined in broilers 3 wks age. Using data from six samples harvested across southeast USA, Pearson correlations were analyzed (r ≥ |0.8|; p < 0.05). Standardized ileal (SIAD) was a previous using eight replicate cages with 13 birds per sample. SIAD values correlated nitrogen fertilization, yield, seeding rate,...
The animal industry is a major sector of agriculture in the southeastern United States, but large deficit exists regional feed grains needed to support industry. An increase production sorghum [ Sorghum bicolor (L.) Moench], water‐ and nutrient‐use‐efficient cereal, on marginal lands could lead an alternative crop option for growers reduce current grain deficit. Quantitative trait locus (QTL) mapping yield components two biparental recombinant inbred line (RIL) populations was performed...
Abstract Population structure is an important factor that affects the accuracy of estimated breeding values in genomic prediction. Natural sorghum [ Sorghum bicolor (L.) Moench] populations exhibit population resulting from genetic and morphological differentiation due to evolutionary divergence. To study impact racial diversity prediction, we conducted two cross‐validation (CV) experiments: CV1, proportional sampling races; CV2, across race (AR) or within (WR). A panel with 389 individuals...
Abstract Multiparent advanced eneration inter-cross (MAGIC) populations improve the precision of quantitative trait loci (QTL) mapping over biparental by incorporating increased diversity and opportunities to reduce linkage disequilibrium among variants. Here, we describe development a MAGIC B-Line (MBL) population from an 4 diverse founders grain sorghum [Sorghum bicolor (L.) Moench] across different races (kafir, guinea, durra, caudatum).
