Development and validation of red root marker-based haploid inducers that effectively complement R1-nj (Navajo) marker-based in vivo haploid identification in maize 

Chaikam, V.; Martinez, L.; Melchinger, A.E.; Schipprack, W.; Prasanna, B.M. (Crop Science Society of America (CSSA), 2016)
One of the critical limitations for the in vivo production of doubled haploid (DH) lines in maize (Zea mays L.) is the inability to effectively identify haploids in a significant proportion of induction crosses due to the ...

Developing and deploying climate-resilient maize varieties in the developing world 

Cairns, J.E.; Prasanna, B.M. (Elsevier, 2018)
In sub-Saharan Africa (SSA) and Asia maize yields remain variable due to climate shocks. Over the past decade extensive progress has been made on the development and delivery of climate-resilient maize. In 2016 over 70 000 ...

Discovery and validation of genomic regions associated with resistance to maize lethal necrosis in four biparental populations 

Gowda, M.; Beyene, Y.; Makumbi, D.; Semagn, K.; Olsen, M.; Jumbo, M.B.; Das, B.; Mugo, S.N.; Mahabaleswara, S.L.; Prasanna, B.M. (Springer Verlag, 2018)
In sub-Saharan Africa, maize is the key determinant of food security for smallholder farmers. The sudden outbreak of maize lethal necrosis (MLN) disease is seriously threatening the maize production in the region. Understanding ...

Genetic diversity and population structure of native maize populations in Latin America and the Caribbean 

Bedoya-Salazar, C.A.; Dreisigacker, S.; Hearne, S.; Franco, J.; Mir, C.; Prasanna, B.M.; Suketoshi Taba; Charcosset, A.; Warburton, M.L. (Public Library of Science, 2017)
This study describes the genetic diversity and population structure of 194 native maize populations from 23 countries of Latin America and the Caribbean. The germplasm, representing 131 distinct landraces, was genetically ...

High-throughput phenotyping of canopy cover and senescence in maize field trials using aerial digital canopy imaging 

Makanza, R.; Zaman-Allah, M.; Cairns, J.E.; Magorokosho, C.; Amsal Tesfaye Tarekegne; Olsen, M.; Prasanna, B.M. (MDPI, 2018)
In the crop breeding process, the use of data collection methods that allow reliable assessment of crop adaptation traits, faster and cheaper than those currently in use, can significantly improve resource use efficiency ...

Application of remote sensing for phenotyping tar spot complex resistance in maize 

Loladze, A.; Rodrigues, F.; Toledo, F.H.; San Vicente, F.M.; Gerard, B.; Prasanna, B.M. (Frontiers, 2019)
Tar spot complex (TSC), caused by at least two fungal pathogens, Phyllachora maydis and Monographella maydis, is one of the major foliar diseases of maize in Central and South America. P. maydis was also detected in the ...

Molecular characterization of diverse CIMMYT maize inbred lines from eastern and southern Africa using single nucleotide polymorphic markers 

Semagn, K.; Magorokosho, C.; Vivek, B.; Makumbi, D.; Beyene, Y.; Mugo, S.; Prasanna, B.M.; Warburton, M.L. (BioMed Central, 2012)
Background: Knowledge of germplasm diversity and relationships among elite breeding materials is fundamentally important in crop improvement. We genotyped 450 maize inbred lines developed and/or widely used by CIMMYT ...

Genome-wide analysis of tar spot complex resistance in maize using genotyping-by-sequencing SNPs and whole-genome prediction 

Shiliang Cao; Loladze, A.; Yibing Yuan; Yongsheng Wu; Ao Zhang; Chen, J.; Huestis, G.M.; Jingsheng Cao; Chaikam, V.; Olsen, M.; Prasanna, B.M.; San Vicente, F.M.; Zhang, X. (Crop Science Society of America, 2017)
Tar spot complex (TSC) is one of the most destructive foliar diseases of maize (Zea mays L.) in tropical and subtropical areas of Central and South America, causing significant grain yield losses when weather conditions ...

Molecular mapping across three populations reveals a QTL hotspot region on chromosome 3 for secondary traits associated with drought tolerance in tropical maize 

Almeida, G.D.; Nair, S.; Borém, A.; Cairns, J.E.; Trachsel, S.; Ribaut, J.M.; Bänziger, M.; Prasanna, B.M.; Crossa, J.; Babu, R. (Springer; Springer Nature, 2014)
Identifying quantitative trait loci (QTL) of sizeable effects that are expressed in diverse genetic backgrounds across contrasting water regimes particularly for secondary traits can significantly complement the conventional ...

Improving maize grain yield under drought stress and non-stress environments in Sub-Saharan Africa using marker-assisted recurrent selection 

Beyene, Y.; Semagn, K.; Crossa, J.; Mugo, S.; Atlin, G.N.; Amsal Tesfaye Tarekegne; Meisel, B.; Sehabiague, P.; Vivek, B.; Oikeh, S.O.; Alvarado Beltrán, G.; Machida, L.; Olsen, M.; Prasanna, B.M.; Bänziger, M. (Crop Science Society of America (CSSA), 2016)
In marker-assisted recurrent selection (MARS), a subset of molecular markers significantly associated with target traits of interest are used to predict the breeding value of individual plants, followed by rapid recombination ...
