Breeding Grain Mold Resistant Sorghum Cultivars
Sorghum (Sorghum bicolor (L.) Moench) is the fifth important cereal crop after wheat (Triticum aestivum L.), maize (Zea mays L.), rice (Oryza sativa L.), and barley (Hordeum vulgare L.) in the world. It is cultivated in about 46 million ha with a total production of 62 million t (FAO 1998). Asia and Africa account 86% of the total area under sorghum, but their contribution towards total product...
متن کاملDevelopment of a transposon-based marker system for mutation breeding in sorghum (Sorghum bicolor L.).
Under certain circumstances, transposable elements (TE) can create or reverse mutations and alter the genome size of a cell. Sorghum (Sorghum bicolor L.) is promising for plant transposon tagging due to its small genome size and its low content of repetitive DNA. We developed a marker system based on targeted region amplification polymorphisms (TE-TRAP) that uses the terminal inverted repeats (...
متن کاملGibberellin deficiency pleiotropically induces culm bending in sorghum: an insight into sorghum semi-dwarf breeding
Regulation of symmetrical cell growth in the culm is important for proper culm development. So far, the involvement of gibberellin (GA) in this process has not yet been demonstrated in sorghum. Here, we show that GA deficiency resulting from any loss-of-function mutation in four genes (SbCPS1, SbKS1, SbKO1, SbKAO1) involved in the early steps of GA biosynthesis, not only results in severe dwarf...
متن کاملPath-dependency in plant breeding: challenges facing participatory reforms in the Ethiopian Sorghum Improvement Program
Participatory plant breeding (PPB) seeks to involve farmers more closely in crop improvement in order to improve the impact of breeding efforts. While detailed discussions exist around appropriate methodologies for conducting PPB, little attention has been directed towards analysing breeding institutions. Such an analysis is necessary, both to understand the possible reasons for poor breeding i...
متن کاملDisaggregating sorghum yield reductions under warming scenarios exposes narrow genetic diversity in US breeding programs.
Historical adaptation of sorghum production to arid and semiarid conditions has provided promise regarding its sustained productivity under future warming scenarios. Using Kansas field-trial sorghum data collected from 1985 to 2014 and spanning 408 hybrid cultivars, we show that sorghum productivity under increasing warming scenarios breaks down. Through extensive regression modeling, we identi...
