Virus infection in potato reduces yield through seed degeneration and can be reduced by use of virus-free seed tubers. Novel approaches are required to ensure availability of virus-free planting stock, especially in countries like Uganda where the seed potato system is still developing. Consequently, a laboratory experiment was conducted in Kachwekano ZARDI in Uganda to evaluate and determine appropriate procedures for... Read more.

Leaf rust (Puccinia triticina Eriks) is the most common rust disease of wheat in wheat-producing areas of Ethiopia. The use of cultivars with durable resistance is the most economical way of controlling the disease. Field experiments were conducted at Ambo Plant Protection Research Center, Ethiopia during 2013 to 2014 main cropping seasons to reveal variability for field based slow rusting resistance to leaf rust among...

Quality seed potato is a key factor in enhancing potato yields in Uganda. Available disease-free seed potato accounts for less than 5% of the whole potato seed market demand in Uganda leaving 95% as seed availability gap. This study was conducted to explore the potential of using farmer managed screen houses to alleviate the seed potato availability gap that exists in Uganda. Six screen houses of 7 m × 14 m each...
