Genetic diversity, linkage disequilibrium and population structure among CIMMYT maize inbred lines, selected for heat tolerance study
(Consiglio per la Ricerca e la sperimentazione in Agricoltura, Unità di Ricerca per la Maiscoltura, 2016)
Rising temperatures has led to reduced maize yields in tropical and sub tropical countries. This provides he necessity for identifying the diverse inbred lines that can produce high yielding hybrids under high temperature ...

Genomic regions associated with root traits under drought stress in tropical maize (Zea mays L.)
(Public Library of Science, 2016)
An association mapping panel, named as CIMMYT Asia association mapping (CAAM) panel, involving 396 diverse tropical maize lines were phenotyped for various structural and functional traits of roots under drought and ...
Article
Use of genomic estimated breeding values results in rapid genetic gains for drought tolerance in maize
(Crop Science Society of America, 2017)
More than 80% of the 19 million ha of maize (Zea mays L.) in tropical Asia is rainfed and prone to drought. The breeding methods for improving drought tolerance (DT), including genomic selection (GS), are geared to increase ...
Article
Genetic analysis of heat adaptive traits in tropical maize (Zea mays L.)
(International Journal of Current Microbiology and Applied Sciences, 2017)
Studies were conducted to determine the gene action for heat adaptive traits and grain yield under heat stress condition by using the hybrids generated in L×T and NCD-II. The results revealed predominance of non-additive ...
Article
Stability for grain yield and other traits in tropical maize (Zea mays L.) under heat stress and optimal conditions
(Excellent Publishers, 2018)
Twenty four newly developed maize hybrids along with three commercial checks were evaluated for their yield performance at three locations under heat stress and optimal conditions. Pooled analysis of variance revealed ...
Article
Pre-germination anaerobic stress tolerance in tropical maize (Zea mays L.)
(Southern Cross Publishing Group, 2012)
Pre-germination anaerobic stress caused by temporary soil water-logging at the planting and seedling establishment stage is an important constraint for maize (Zea mays L.) production in the tropics, especially in South and ...

Genome-wide association study in Asia-adapted tropical maize reveals novel and explored genomic regions for sorghum downy mildew resistance
(Nature Publishing Group, 2017)
Globally, downy mildews are among the important foliar diseases of maize that cause significant yield losses. We conducted a genome-wide association study for sorghum downy mildew (SDM; Peronosclerospora sorghi) resistance ...
Article
Evaluation of grain yield of heat stress resilient maize hybrids in Nepal
(International Journal of Applied Sciences and Biotechnology, 2017)
Midhills, foot hills and river basin areas of are generally under spring maize cultivation. These areas along with the areas from Terai and Inner Terai where spring and early summer maize are grown are the most affected ...
Article
Line x testers analysis of tropical maize inbred lines under heat stress for grain yield and secondary traits
(Consiglio per la Ricerca e la sperimentazione in Agricoltura, Unità di Ricerca per la Maiscoltura, 2016)
The combining ability and mode of gene action in tropical maize germplasm is not extensively studied. In the present study, a line x tester analysis involving 290 test-cross hybrids developed by crossing 145 tropical maize ...
