Review of advances in plant biotechnology, 1985-88
(IRRI; CIMMYT, 1989)
There is great potential for biotechnology as a tool in crop breeding. Despite the risk in such upstream research, many plant breeders are becoming more involved in this work to facilitate the rapid exploitation of new ...
Testcross performance of doubled haploid maize lines derived from tropical adapted backcross populations
(Consiglio per la Ricerca e la sperimentazione in Agricoltura, Unità di Ricerca per la Maiscoltura, 2011)
Doubled haploid (DH) lines produced by in vivo induction of maternal haploids are routinely used in maize breeding. The present study was carried out to assess the performance of 75 doubled haploid maize testcrosses and ...
Quantitative trait locus mapping with background control in genetic populations of clonal F1 and double cross
In this study, we considered five categories of molecular markers in clonal F1 and double cross populations, based on the number of distinguishable alleles and the number of distinguishable genotypes at the marker locus. ...
Genotype by environment interactions and agronomic performance of doubled haploids testcross maize (Zea mays L.) hybrids
In vivo production of maternal haploid plants and advancement in chromosome doubling technology has led to rapid production of doubled haploid homozygous lines. These in turn have boosted rapid advancement in most breeding ...
Development and validation of red root marker-based haploid inducers that effectively complement R1-nj (Navajo) marker-based in vivo haploid identification in maize
(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 ...
Genome wide association mapping for heat tolerance in sub-tropical maize
(BioMed Central, 2021)
Identification of in vivo induced maternal haploids in maize using seedling traits
In vivo haploid induction in high frequency followed by efficient identification of haploids are important components of deriving completely homozygous doubled haploid (DH) lines in maize. Several genetic marker systems ...
Performance and adaptability of doubled haploid maize testcross hybrids under drought stress and non-stress conditions
(International Research Journals, 2014)
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 ...
Marker-assisted breeding of improved maternal haploid inducers in maize for the tropical/subtropical regions
For efficient production of doubled haploid (DH) lines in maize, maternal haploid inducer lines with high haploid induction rate (HIR) and good adaptation to the target environments is an important requirement. In this ...
