Genetic trends in CIMMYT's tropical maize breeding pipelines. [PDF]

Sci Rep, 2022
AbstractFostering a culture of continuous improvement through regular monitoring of genetic trends in breeding pipelines is essential to improve efficiency and increase accountability. This is the first global study to estimate genetic trends across the International Maize and Wheat Improvement Center (CIMMYT) tropical maize breeding pipelines in ...

Haploid induction and its application in maize breeding. [PDF]

Mol Breed, 2021
Maize is a heterosis-utilizing crop species, and the application of maize hybrids has significantly improved total maize yields worldwide. Breeding pure lines is the most important part of heterosis utilization. The double haploid (DH) breeding technology is the approach rising recently in breeding pure lines; compared to the conventional recurrent ...

Characterization of Proteome Variation During Modern Maize Breeding. [PDF]

Mol Cell Proteomics, 2019
The success of modern maize breeding has been demonstrated by remarkable increases in productivity with tremendous modification of agricultural phenotypes over the last century. Although the underlying genetic changes of the maize adaptation from tropical to temperate regions have been extensively studied, our knowledge is limited regarding the ...

OpenEar: an ultra-affordable, high-throughput, and accurate maize ear phenotyping system [PDF]

Plant Methods
Crop phenotyping of important agronomic traits in field conditions at single-plant resolution has long been a major bottleneck in both genetic analysis (e.g. large-scale association/linkage analysis) and breeding applications (e.g.

Genetic trends in the Zimbabwe’s national maize breeding program over two decades [PDF]

Frontiers in Plant Science
Monitoring genetic gains within breeding programs is a critical component for continuous improvement. While several national breeding programs in Africa have assessed genetic gain using era studies, this study is the first to use two decades of ...

Comparative analysis of mitochondrial genomes of maize CMS-S subtypes provides new insights into male sterility stability

BMC Plant Biology, 2022
Background Cytoplasmic male sterility (CMS) is a trait of economic importance in the production of hybrid seeds. In CMS-S maize, exerted anthers appear frequently in florets of field-grown female populations where only complete male-sterile plants were ...

Drought and Maize Breeding

IOP Conference Series: Earth and Environmental Science, 2022
Abstract Tension caused by a lack of water (water stress or drought stress) represents the continuous and continuous threat to the survival of the plant, as many of the plants in which phenotypic or physiological modification takes place may not be able to continue and remain in the environment in which they live due to the water stress ...

iTRAQ-based quantitative proteomic analysis provides insight into the drought-stress response in maize seedlings

Scientific Reports, 2022
Drought is a major abiotic stress that harms plant cell physiology and limits the growth and productivity of crops. Maize (Zea mays L.), one of the most drought-susceptible crops, is a major food source for humans and an important resource for industrial

Identification of a locus associated with genic male sterility in maize via EMS mutagenesis and bulked-segregant RNA-seq

Crop Journal, 2021
Genic male sterility (GMS) is one of the most important resources for exploiting heterosis in crop breeding, so that identifying genomic loci regulating GMS is desirable.
