Genomic selection (GS) unlike marker-assisted backcrossing (MABC) predicts breeding values of lines using genome-wide marker profiling and allows prior to field-phenotyping, thereby shortening the cycle. A collection 320 elite was selected phenotyped extensively for yield related traits at two different locations (Delhi Patancheru, India) during crop seasons 2011-12 2012-13 under rainfed irrigated conditions. In parallel, these were also genotyped DArTseq platform generate data on 3,000...
The low grain iron and zinc densities are well documented problems in food crops, affecting crop nutritional quality especially cereals.

Chickpea (Cicer arietinum L.), a cool-season legume, is increasingly affected by heat-stress at reproductive stage due to changes in global climatic conditions and cropping systems. Identifying quantitative trait loci (QTLs) for heat tolerance may facilitate breeding tolerant varieties. The present study was aimed identifying QTLs associated with chickpea using 292 F8-9 recombinant inbred lines (RILs) developed from the cross ICC 4567 (heat sensitive) × 15614 tolerant). Phenotyping of RILs...

Abstract There is growing interest in the conservation and utilization of crop wild relatives (CWR) international food security policy research. Legumes play an important role human health, sustainable production, global security, resilience current agricultural systems. Pea belongs to ancient set cultivated plants Near East domestication center remains today. Based on genome-wide analysis, P . fulvum was identified as a well-supported species, while diversity sativum subsp. elatius...
Heterogeneous and multidisciplinary data generated by research on sustainable global agriculture agrifood systems requires quality labeling or annotation in order to be interoperable. As recommended the FAIR principles, data, labels, metadata must use controlled vocabularies ontologies that are popular knowledge domain commonly used community. Despite existence of robust Life Sciences, there is currently no comprehensive full set for across agricultural disciplines. In this paper, we discuss...
Fusarium wilt (FW) is one of the most important biotic stresses causing yield losses in pigeonpea. Genetic improvement pigeonpea through genomics-assisted breeding (GAB) an economically feasible option for development high yielding FW resistant genotypes. In this context, two recombinant inbred lines (RILs) (ICPB 2049 × ICPL 99050 designated as PRIL_A and 20096 332 PRIL_B) F2 (ICPL 85063 87119) populations were used density genetic maps. Genotyping-by-sequencing (GBS) approach was to...
Sterility mosaic disease (SMD) is one of the serious production constraints that may lead to complete yield loss in pigeonpea. Three mapping populations including two recombinant inbred lines and F2, were used for phenotyping SMD resistance at locations three different years. Genotyping-by-sequencing approach was simultaneous identification genotyping SNPs on above mentioned populations. In total, 212,464, 89,699 64,798 identified ICPL 20096 × 332 (PRIL_B), 20097 ICP 8863 (PRIL_C) 87119 (F2)...
Pea, one of the founder crops from Near East, has two wild species: Pisum sativum subsp. elatius, with a wide distribution centered in Mediterranean, and P. fulvum, which is restricted to Syria, Lebanon, Israel, Palestine Jordan. Using genome analysis 11,343 polymorphic single nucleotide polymorphisms (SNPs) on set elatius (134) fulvum (20) 74 domesticated accessions (64 landraces 10 abyssinicum), we demonstrated that Ethiopian pea (P. abyssinicum) were derived different genepools....
As one of the major outputs next-generation sequencing (NGS), a large number genome-wide single-nucleotide polymorphisms (SNPs) have been developed in pigeonpea [ (L.) Huth.]. However, SNPs require genotyping platform or assay to be used different evolutionary studies crop improvement programs. Therefore, we an Axiom SNP array with 56K uniformly distributed across genome and assessed its utility genetic diversity study. From whole-genome resequencing (WGRS) data on 104 lines, ∼2 million...
Exploring the natural genetic variability and its exploitation for improved Nitrogen Use Efficiency (NUE) in sorghum is one of primary goals modern crop improvement programs. The integrated strategies include high-throughput phenotyping, next generation sequencing (NGS)-based genotyping technologies, a priori selected candidate gene studies that help understand detailed physiological molecular mechanisms underpinning this complex trait. A set sixty diverse genotypes was evaluated different...
ABSTRACT The first sorghum [ Sorghum bicolor (L.) Moench] hybrids based on West African Guinea‐race‐derived parents were created to enhance farmer's food security and income through increased yields. To assess their performance, eight hybrids, six experimental pure‐line cultivars, one check (Lata), a highly adapted landrace cultivar (Tieble) evaluated in 27 farmer‐managed two on‐station yield trials Mali, Africa, from 2009 2011. confirmed have photoperiod sensitivity similar the well‐adapted...
Genetic distances between hybrid parents based on phenotypic traits and molecular markers were investigated to assess their relationship with heterosis for grain stover yield other in pearl millet (Pennisetum glaucum [L.] R. Br.). Fifty-one hybrids developed using 101 (B R lines) showing a wide range of genetic distance eight 28–38 SSRs evaluated two sets seasons. The correlation Euclidean (phenotypic distance, ED) simple matching (molecular SM) both was low but positive significant (r =...
ABSTRACT Pearl millet [ Pennisetum glaucum (L.) R. Br.] is grown under a wide range of environmental conditions in India. The All India Coordinated Millet Improvement Project (AICPMIP) has the responsibility testing and releasing pearl cultivars adapted to such conditions. As part this process, AICPMIP divided entire growing regions into three different zones (A 1 , A, B) based on rainfall pattern local adaptation crop. This study was conducted define presently used test locations possible...
Nitrogen (N) is one of the primary macronutrients required for crop growth and yield. This nutrient especially limiting in dry low fertility soils where pearl millet [ Pennisetum glaucum (L.) R. Br] typically grown. Globally, sixth most important cereal grown by subsistence farmers arid semi-arid regions sub-Saharan Africa Indian subcontinent. Most these agro-ecologies have N root zone soil strata. Therefore, there an immense need to identify lines that use nitrogen efficiently. A set 380...

Abstract Pearl millet [ Pennisetum glaucum (L.) R. Br.] is a staple food crop of arid and semi‐arid regions Asia Africa. Forty‐five pearl populations Asian African origin were assessed for genetic diversity using 29 simple sequence repeat (SSR) markers. The SSR‐based clustering structure analyses showed that origin–Asian bred (As‐As) origin–African (Af‐Af) distributed across seven clusters, indicating no strong relationship among with their geographical origin. Most the (Af‐As) had higher...
