Ochieng-Obura, B.Kimoone, G.Bararyenya, A.Tindimubona, S.Kinyua, Z.M.Schulte-Geldermann, Elmar[Positive selection to improve quality of farmers seed potato.]Positive selection to improve quality of farmers seed potato.

Grain mold, induced by a number of non-specific fungi, causes substantial loss to seedgrain yield and quality in sorghum (Sorghum bicolor (L.) Moench). Fungal sporulation and grain mold severity are greatly influenced by temperature and relative humidity (RH) levels. We studied the effects of thr...

Moench)]Effect of temperature and humidity regimes on grain mold sporulation and seed quality in sorghum (Sorghum bicolor (L.) Moench)

Meeting the multimillion hectare commitments for forest and landscape restoration (FLR) will require billions of tree seed and seedlings. However, the adequacy of seed supply in terms of quantity, genetic diversity and quality has received scant attention in FLR planning. We surveyed 139 FLR proj...

The poor knowledge about the presence of diseases and pests affecting the potato crop in developing countries difficult the understanding of their distribution in agro-ecological systems and consequent effect on yield and seed quality. A combination of a monitoring and a field experiment were per...

Seed size and protein content are the major breeding objectives for cowpeas (Vigna unguiculata). However, intra-plant variation in these traits causes heterogeneous seed quality and seed depreciation. To determine the causes and severity of intra-plant variation in cowpea single seed weight and p...

Trials have been conducted at two sites in the subhumid zone of Nigeria to investigate the influence of weed control on seed quantity and quality using three tropical forage legumes, Centrosema pascuorum cv Cavalcade, Chamaecrista rotundifolia cv Wynn and Stylosanthes hamata cv Verano. Manaual we...

This study analyses rice and finger millet seed systems in Nepal, particularly in Ghanpokhara (Lamjung) and compares them with the seed systems found in other parts of the country. It presents factors that influence seed availability and accessibility for rice and finger millet along the continuu...

One of the objectives of the SASHA project is to strengthen technical, financial and institutional capacities for the sustainable production of pre-basic sweetpotato seed in 11 sub-Saharan African countries. This flyer outlines the schematic of sweetpotato seed system and the progress made from J...
