A disease test at different leaf layers (plant stages) of homologous rust and heterologous rust species were studied. The result from homologous rust species showed that those quantitative trait loci (QTLs) (Rphq2 and Rphq11) which were effective at seedling stage were also effective across all plant stages with gradually decreasing effect as plants grew older. Rphq3 which had consistent effect in all leaf layers... Read more.

Stem rust (Puccinia graminis f. sp tritici) poses a major threat to wheat (Triticum aestivum L.) production worldwide. The interaction between wheat and pathogen in presence of favorable environment can cause a complete crop failure. This study was conducted with the objective to identify wheat genotypes with resistance to stem rust with high and stable yield under four environments in Kenya. Forty wheat genotypes were...

Seed size variation has implications for the success of seedling establishment, but the underlying mechanisms are yet to be fully explored in many species, including Khaya senegalensis. Moreover, seed size is measured in different ways (for example, mass or length), but the extent to which these different ways of measurement differ in predicting seedling growth parameters is unknown. In this study, how well seed mass... Read more.
