Publication - GWAS to identify genetic loci for resistance to yellow rust in wheat pre-breeding lines derived from diverse exotic crosses(Frontiers, 2019) Ledesma-Ramirez, L.; Solís Moya, E.; Iturriaga, G.; Sehgal, D.; Reyes-Valdés, M.H.; Montero-Tavera, V.; Sansaloni, C.; Burgueño, J.; Ortiz, C.; Aguirre-Mancilla, C.L.; Ramirez-Pimentel, J.G.; Vikram, P.; Singh, S.
Publication - Relationship between the number of partial resistance genes and the response to leaf rust in wheat genotypes(INIA, 2018) Ledesma-Ramires, L.; Solís Moya, E.; Ramirez-Pimentel, J.G.; Dreisigacker, S.; Huerta-Espino, J.; Aguirre-Mancilla, C.L.; Mariscal-Amaro, L.A.The adult plant resistance conferred by genes with an additive effect is an alternative to achieve durable resistance to leaf rust caused by the fungus Puccinia triticina in wheat (Triticum spp.) The objective of this study was to know the response to this disease in bread wheat genotypes that possess the partial resistance genes Lr34, Lr46, Lr67 and Lr68. The severity level of the disease was measured in 280 wheat genotypes in three locations. The presence or absence of partial resistance genes was determined by molecular markers for each gene in 245 wheat genotypes. The different combinations of adult plant genes resulted in the genotypes were classified into nine groups. In 77 of these genotypes, the markers were negative for these genes. The Lr34, Lr46, Lr67 and Lr68 genes were identified individually in 48, 48, 5, and 14 genotypes, respectively. The combination of two genes, Lr34+Lr46, Lr34+Lr68 and Lr46+Lr68, was determined in 18, 17, and 12 genotypes, respectively. Only in six genotypes the combination Lr34+Lr46+Lr68 was identified. The genotypes with the Lr34, Lr46, Lr67 and Lr68 genes in a unique form showed 21%, 24.8%, 21.9% and 21.8% of rust severity on average, respectively. An additive effect was observed in the combinations of two genes, and higher effect in the combinations that included the Lr34 gene since genotypes with this gene combination showed on average 11.4% of rust severity. The combination of three genes Lr34+Lr46+Lr68 provide greater protection in the genotypes with 9.7% of rust severity on average.
Publication - Harnessing genetic potential of wheat germplasm banks through impact-oriented-prebreeding for future food and nutritional security(Nature Publishing Group, 2018) Singh, S.; Vikram, P.; Sehgal, D.; Burgueño, J.; Sharma, A.R.; Singh, S.K.; Sansaloni, C.; Joynson, R.; Brabbs, T.; Ortiz, C.; Solís Moya, E.; Velu, G.; Gupta, N.; Sidhu, H.S.; Basandrai, A.K.; Basandrai, D.; Ledesma-Ramires, L.; Suaste-Franco, M.P.; Fuentes Dávila, G.; Ireta Moreno, J.; Sonder, K.; Vaibhav K.

Chaudhary; Crossa, J.; Payne, T.S.; Imtiaz, M.; Sohu, V.S.; Singh, G.P.; Bains, N.; Hall, A.J.W.; Pixley, K.V.The value of exotic wheat genetic resources for accelerating grain yield gains is largely unproven and unrealized. We used next-generation sequencing, together with multi-environment phenotyping, to study the contribution of exotic genomes to 984 three-way-cross-derived (exotic/elite1//elite2) pre-breeding lines (PBLs). Genomic characterization of these lines with haplotype map-based and SNP marker approaches revealed exotic specific imprints of 16.1 to 25.1%, which compares to theoretical expectation of 25%. A rare and favorable haplotype (GT) with 0.4% frequency in gene bank identified on chromosome 6D minimized grain yield (GY) loss under heat stress without GY penalty under irrigated conditions. More specifically, the ‘T’ allele of the haplotype GT originated in Aegilops tauschii and was absent in all elite lines used in study. In silico analysis of the SNP showed hits with a candidate gene coding for isoflavone reductase IRL-like protein in Ae. tauschii. Rare haplotypes were also identified on chromosomes 1A, 6A and 2B effective against abiotic/biotic stresses. Results demonstrate positive contributions of exotic germplasm to PBLs derived from crosses of exotics with CIMMYT’s best elite lines. This is a major impact-oriented pre-breeding effort at CIMMYT, resulting in large-scale development of PBLs for deployment in breeding programs addressing food security under climate change scenarios.

In this study, crosses were designed to complement “source” with “sink” traits, where at least one parent was selected for favorable expression of biomass and/or radiation use efficiency—source—and the other for sink-related traits like harvest-index, kernel weight and grains per spike. Female parents were selected from among genetic resources—including landraces and products of wide-crossing (i.e. synthetic wheat)—that had been evaluated in Mexico at high yield potential or under heat stress, while elite lines were used as males. Progeny of crosses were advanced to the F4 generation within Mexico, and F4-derived F5 and F6 generations were yield tested to populate four international nurseries, targeted to high yield environments (2nd and 3rd WYCYT) for yield potential, and heat stressed environments (2nd and 4th SATYN) for climate resilience, respectively. Each nursery was grown as multi-location yield trials. Genetic gains were achieved in both temperate and hot environments, with most new PT-derived lines expressing superior yield and biomass compared to local checks at almost all international sites. Furthermore, the tendency across all four nurseries indicated either the superiority of the best new PT lines compared with the CIMMYT elite checks, or the superiority of all new PT lines as a group compared with all checks, and in some cases, both. Results support—in a realistic breeding context—the hypothesis that yield and radiation use efficiency can be increased by improving source:sink balance, and validate the feasibility of incorporating exotic germplasm into mainstream breeding efforts to accelerate genetic gains for yield potential and climate resilience.
Publication - Genomic prediction models for grain yield of spring bread wheat in diverse agro-ecological zones(Nature Publishing Group, 2016) Saint Pierre, C.; Burgueño, J.; Fuentes Dávila, G.; Figueroa, P.; Solís Moya, E.; Ireta Moreno, J.; Hernández Muela, V.M.; Zamora Villa, V.; Vikram, P.; Mathews, K.L.; Sansaloni, C.; Sehgal, D.; Jarquin, D.; Wenzl, P.; Singh, S.; Crossa, J.Genomic and pedigree predictions for grain yield and agronomic traits were carried out using high density molecular data on a set of 803 spring wheat lines that were evaluated in 5 sites characterized by several environmental co-variables. Seven statistical models were tested using two random cross-validations schemes. Two other prediction problems were studied, namely predicting the lines’ performance at one site with another (pairwise-site) and at untested sites (leave-one-site-out). Grain yield ranged from 3.7 to 9.0 t ha−1 across sites. The best predictability was observed when genotypic and pedigree data were included in the models and their interaction with sites and the environmental co-variables. The leave-one-site-out increased average prediction accuracy over pairwise-site for all the traits, specifically from 0.27 to 0.36 for grain yield. Days to anthesis, maturity, and plant height predictions had high heritability and gave the highest accuracy for prediction models. Genomic and pedigree models coupled with environmental co-variables gave high prediction accuracy due to high genetic correlation between sites. This study provides an example of model prediction considering climate data along-with genomic and pedigree information. Such comprehensive models can be used to achieve rapid enhancement of wheat yield enhancement in current and future climate change scenario.
Publication - Transferencia del gen Lr14a de trigos harineros a trigos cristalinos y expresion de la resistencia a roya de la hoja(Sociedad Mexicana de Fitogenética, 2010) Huerta-Espino, J.; Singh, R.P.; Villaseñor Mir, H.E.; Solís Moya, E.; Espitia-Rangel, E.; Leyva Mir, S.GEl origen del gen de resistencia Lr14a a roya de la hoja causada por Puccinia triticina E. es el trigo tetraploide 'Yaroslav emmer' (Triticum dicoccum L.). En México, todas las razas de trigo harinero (T. aestivum) importantes son virulentas a este gen. Sin embargo, las razas que atacan trigos cristalinos o duros son avirulentas a Lr14a. Se ha determinado la presencia de Lr14a en trigo harinero y en especies silvestres tetraploides, pero no en trigos cristalinos o trigos duros (T. turgidum spp durum). El gen Lr14a se transfirió a la variedad cristalina 'Altar C84' a partir de la cruza de ésta con la línea monogénica de trigo harinero 'RL6013' (Selkirk/6*Thatcher) y una retrocruza hacia 'Altar C84'. Para determinar la genética de la resistencia de la variedad 'Jupare C2001', resistente a la raza de roya de la hoja que venció la resistencia de 'Altar C84', y determinar si 'Jupare C2001' posee Lr14a, se cruzó con 'Altar C84' y con 'Altar C84' +Lr14a. La respuesta del gen de resistencia a roya de la hoja Lr14a a la infección en plántula a las razas BBG/BN y BCG/BN que son virulentas en 'Altar C84', es de heterogénea con uredinios grandes (X a X+) en la escala de 0–4, tanto en trigos harineros como en 'Altar C84', mientras que confiere casi inmunidad en planta adulta a estas mismas razas. La cruza de 'Jupare C2001' con 'Altar C84' +Lr14a indicó que 'Jupare C2001' no posee Lr14a, y que la resistencia de esta última se basa en dos genes complementarios dominantes. Para el funcionamiento efectivo de la resistencia que el gen Lr14a confiere en trigos cristalinos en respuesta a las razas de roya de la hoja que preferentemente atacan trigos harineros, es necesaria la presencia del gen de 'Altar C84'.
