Abstract:
... Breeding for host resistance to coffee berry disease (CBD) in arabica coffee (Coffea arabica) was initiated some 35-40 years ago in Kenya, Ethiopia and Tanzania in response to severe CBD epidemics. The release of CBD resistant cultivars to the coffee growers has been in progress since 1985. The resistance of cultivars like Ruiru 11 (Kenya) and Ababuna (and other cvs in Ethiopia) appears to be of a ...

Abstract:
... Farmers' seeds are most often lumped together in one broad category called 'landraces'. But such a category covers variety types that reflect different levels of farmer involvement. Those differences matters when we discuss such issues as genetic erosion, on-farm conservation and seed related policies. The term landrace can be traced to the time when 'modern' varieties of cereals were introduced t ...

Abstract:
... Preharvest sprouting (PHS) in spring wheat (Triticum aestivum L.) causes significant economic losses due to a reduction in grain functionality, grain yield and viability of seed for planting. Genetic resistance to PHS reduces these losses. Development of PHS resistant cultivars is complicated by the effects of genotype, environment, kernel diseases and spike morphological factors. RL4137 has consi ...
