Pearl millet [Cenchrus americanus (L.) Morrone] is a staple food for more than 90 million farmers in arid and semi-arid regions of sub-Saharan Africa, India South Asia. We report the ∼1.79 Gb draft whole genome sequence reference genotype Tift 23D2B1-P1-P5, which contains an estimated 38,579 genes. highlight substantial enrichment wax biosynthesis genes, may contribute to heat drought tolerance this crop. resequenced analyzed 994 pearl lines, enabling insights into population structure,...
To achieve the food and energy security of an increasing World population likely to exceed nine billion by 2050 represents a major challenge for plant breeding. Our ability measure traits under field conditions has improved little over last decades currently constitutes bottleneck in crop improvement. This work describes development tractor-pulled multi-sensor phenotyping platform small grain cereals with focus on technological system. Various optical sensors like light curtain imaging, 3D...
Modeling epistasis in genomic selection is impeded by a high computational load. The extended best linear unbiased prediction (EG-BLUP) with an epistatic relationship matrix and the reproducing kernel Hilbert space regression (RKHS) are two attractive approaches that reduce In this study, we proved equivalence of EG-BLUP approaches, explicitly modeling effects. Moreover, have shown why RKHS model based on Gaussian captures effects among markers. Using experimental data sets wheat maize,...
Barley, globally the fourth most important cereal, provides food and beverages for humans feed animal husbandry. Maximizing grain yield under varying climate conditions largely depends on optimal timing of flowering. Therefore, regulation flowering time is extraordinary importance to meet future demands. We developed first barley nested association mapping (NAM) population, HEB-25, by crossing 25 wild barleys with one elite cultivar, used it dissect genetic architecture time.Upon cultivation...
Significance Selfing species wheat are bred as pure-line varieties with stagnating yield growths. In contrast, selection gain in maize is high, owing to massive investment sustained by hybrid seed sales, coupled an efficient exploitation of vigor. We have developed a three-step strategy for establishing heterotic pattern, which was one the central unsolved challenges initiating breeding programs. The benefits our approach demonstrated using data wheat, but relevant several autogamous crops....
Heterotic groups and patterns are of fundamental importance in hybrid breeding maize ( Zea mays L.). The major goal this study was to investigate the relationship between heterosis genetic distance determined with simple sequence repeat (SSR) markers. objectives our research were (i) compare diversity within seven tropical populations, (ii) test alternative hypotheses on panmictic midparent (PMPH) distances SSR markers, (iii) evaluate use markers for grouping germplasm establishing heterotic...
A proper choice of a dissimilarity measure is important in surveys investigating genetic relationships among germplasm with molecular marker data. The objective our study was to examine 10 coefficients widely used surveys, special focus on applications plant breeding and seed banks. In particular, we (i) investigated the genetical mathematical properties these coefficients, (ii) examined consequences for different areas application banks, (iii) determined between coefficients. concepts were...
Abstract Background Artificial selection played an important role in the origin of modern Glycine max cultivars from wild soybean soja . To elucidate consequences artificial accompanying domestication and improvement soybean, 25 new 30 published whole-genome re-sequencing accessions, which represent wild, domesticated landrace, Chinese elite populations were analyzed. Results A total 5,102,244 single nucleotide polymorphisms (SNPs) 707,969 insertion/deletions identified. Among SNPs detected,...
ABSTRACT Accurate prediction of single cross performance is fundamental importance to increase the selection gain in wheat ( Triticum aestivum L.) hybrid breeding programs. We used experimental data from a commercial program as well simulated sets and evaluated prospects predicting grain yield untested hybrids applying different cross‐validation scenarios. ridge regression best linear unbiased (RR‐BLUP), BayesA, BayesB, BayesC, BayesCπ facilitating genomic for additive dominance effects. In...
We present a theoretical proof that the ratio of dominance vs. additive variance decreases with increasing genetic divergence between two populations. While is major component due to specific combining ability (sigma(SCA)(2)), general (sigma(GCA)(2)). Therefore, we conclude interpopulation improvement becomes more efficient divergent than genetically similar heterotic groups, because performance superior hybrids can be predicted on basis effects.
