Genotypic Variation in Seedling Tolerance to Aluminum Toxicity in Historical Maize Inbred Lines of Zambia
Maize (Zea mays L) is the most important food grain in sub-Saharan Africa and is mostly grown by small-scale farmers under rainfed conditions. Aluminum toxicity caused by low pH is one of the abiotic factors limiting maize production among smallholder farmers. Therefore, breeding maize hybrids that are tolerant to aluminum toxicity will sustain and increase maize production in these areas. Henc...
متن کاملSSR Variation in Important U.S. Maize Inbred Lines
that some of the inbreds continued to contribute substantially to hybrids marketed in the USA. For example, Historically important public inbred lines continue to play an imB73 and Mo17 were used in about 28% of all seed portant role in maize (Zea mays L.) improvement in many different breeding programs. Their continued use means they have undergone planted in the USA in 1979. This fell to 12.8...
متن کاملDetermination of levels of Striga germination Stimulants for maize gene bank accessions and elite inbred lines
Parasitism by Striga hermonthica (Del) Benth is a severe constraint in maizeproduction in sub-Saharan Africa. Varying levels of tolerance to Striga attack havebeen identified and exploited in breeding programs of several crops. However, thelevel and stability of the tolerance is generally unacceptable in field-practice. Onlylimited exploration has been undertaken among the farmers’ landraces to...
متن کاملGenetic variation for grain mineral content in tropical-adapted maize inbred lines.
Increasing the concentrations of Fe and Zn in staple food crops through breeding has been proposed as one strategy to minimize the adverse effects of widespread mineral deficiencies in humans. This approach requires the presence of adequate genetic differences in concentrations of grain minerals for improvement. Eight trials involving different sets of tropical maize inbred lines adapted to the...
متن کاملEpigenetics and genetics: global profiling in maize inbred lines examines variation in DNA methylation.
DNA methylation provided one of the first clues to the mechanisms of epigenetic regulation, explaining mysterious phenomena like transgene silencing in plants and oddities of inheritance in maize (Zea mays) and other species. Further research revealed that genomic DNA, and the histones that bundle it into chromatin, can be modified in different ways; these modifications affect gene expression a...
