Use of genomic estimated breeding values results in rapid genetic gains for drought tolerance in maize
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 ...
A hierarchical bayesian estimation model for multienvironment plant breeding trials in successive years
(Crop Science Society of America, 2016)
In agriculture and plant breeding, multienvironment trials over multiple years are conducted to evaluate and predict genotypic performance under different environmental conditions and to analyze, study, and interpret ...
Combining ability and heterosis in tropical maize (Zea mays L.) under heat stress
(Society of Pharmacognosy and Phytochemistry, 2018)
Maize cultivars tolerant to heat stress could play a pivotal role in adapting to the intermittent high temperature at critical growth stages and cope-up with climate-change induced high temperature spells. Field experiments ...
Genomic-enabled prediction in maize using kernel models with genotype x environment interaction
(Genetics Society of America, 2017)
Multi-environment trials are routinely conducted in plant breeding to select candidates for the next selection cycle. In this study, we compare the prediction accuracy of four developed genomic-enabled prediction models: ...
Conservation agriculture in southern Africa: advances in knowledge
(Cambridge University Press, 2015)
The increasing demand for food from limited available land, in light of declining soil fertility and future threats of climate variability and change have increased the need for more sustainable crop management systems. ...
Introgression of the crtRB1 gene into quality protein maize inbred lines using molecular markers
(Springer; Springer Nature, 2015)
Quality protein maize (QPM; Zea mays L.) has effectively enhanced levels of the amino acids, lysine, and tryptophan, over normal maize and provided balanced dietary protein for the health and development of monogastric ...
Grain-yield stability among tropical maize hybrids derived from doubled-haploid inbred lines under random drought stress and optimum moisture conditions
Drought is a devastating environmental stress in agriculture and hence a common target of plant breeding. A review of breeding progress on drought tolerance shows that, to a certain extent, selection for high yield in ...
Identification of QTL for early vigor and Stay-Green conferring tolerance to drought in two connected advanced backcross populations in Tropical Maize (Zea mays L.)
(Public Library of Science, 2016)
We aimed to identify quantitative trait loci (QTL) for secondary traits related to grain yield (GY) in two BC1F2:3 backcross populations (LPSpop and DTPpop) under well-watered (4 environments; WW) and drought stressed (6; ...
