Introgression of root protein and yield traits from backcross hybrids between cassava and its wild progenitor (Manihot esculenta ssp flabellifolia)

Manihot esculenta spp flabellifolia is a potential progenitor for cassava root protein content and yield improvement. Storage roots of cassava landraces are low in protein content due to the fact that past breeding objectives concentrated mainly on yield and resistance to diseases. The improvement of cassava through its wild progenitor is of importance for the full utilization of the potential of the wild progenitor. An...

Correlation analysis for maize grain yield, other agronomic parameters and Striga affected traits under Striga infested/free environment

Evaluation of 15 F1 hybrids and six parents obtained from partial diallel crosses was carried out during 2011 rainy season at Institute of Agricultural Research (IAR) Samaru, Zaria Striga infested field and Striga free field (2 environments). Interrelationships of grain yield and its components under Striga infestation revealed that character ear height had positive and highly significant phenotypic correlation with...

Genetics of drought tolerance in common bean genotypes adapted to Ugandan conditions

Common bean (Phaseolus vulgaris L.) is an important source of food and income for majority of households in Sub-Saharan Africa. However, bean production in Uganda is being affected by drought which has resulted from recent changes in climate. Developing high-yielding and drought-tolerant bean cultivars would significantly contribute to increased and stable yields in drought-prone environments. However, prior research...
