Gains in maize genetic improvement in Eastern and Southern Africa : I. CIMMYT hybrid breeding pipeline
Monitoring of genetic gain in crop genetic improvement programs is necessary to measure the efficiency of the program. Periodic measurement of genetic gain also allows the efficiency of new technologies incorporated into ...
Comparative analysis of carotenoid and tocopherol compositions in high-oil and normal maize (Zea mays L.) inbreds
Among staple crops, maize has a high amount of carotenoids and tocopherols, which have a number of beneficial effects on human health. The former is the main dietary precursor of vitamin A. The latter is an essential ...
The genetic architecture of flowering time and photoperiod sensitivity in maize as revealed by QTL review and meta analysis
The control of flowering is not only important for reproduction, but also plays a key role in the processes of domestication and adaptation. To reveal the genetic architecture for flowering time and photoperiod sensitivity, ...
Combining ability and reciprocal cross effects of elite quality protein maize inbred lines in subtropical environments
General combining ability (GCA), specific combining ability (SCA), and reciprocal cross effects information facilitate efficient utilization of inbred lines in a breeding program. A diallel analysis of nine quality protein ...
Bt-transgenic maize does not deter oviposition by two important African cereal stem borers, Chilo partellus Swinhoe (Lepidoptera: Crambidae) and Sesamia calamistis Hampson (Lepidoptera: Noctuidae)
Objective: To assess Chilo partellus Swinhoe (Lepidoptera: Crambidae) and Sesamia calamistis Hampson (Lepidoptera: Noctuidae) ovipositional responses on Bt (Event 216, containing the Cry1Ab gene) and isogenic non-Bt (CML ...
Combining ability among twenty insect resistant maize inbred lines resistant to Chilo partellus and Busseola fusca Stem borers
A partial diallel design was used among 20 maize inbred lines to form 110 F1 hybrids to generate information on the values of these lines for developing insect resistant maize varieties during the short rains season of ...
CIMMYT maize hybrids for latin america: Head-to-head analysis and probability of outperforming the best check
The best-performing maize hybrid sent to Latin America in 1994 as part of the first CIMMYT international hybrid trials, and later used as a regular check in trials, was CML247 x CML254, a cross between two excellent CIMMYT ...
Molecular characterization of CIMMYT maize inbred lines with genotyping-bysequencing SNPs
Key message Molecular characterization information on genetic diversity, population structure and genetic relationships provided by this research will help maize breeders to better understand how to utilize the current CML ...
