This study uses ecological system theory to examine the micro and meso level factors that affect and are affected potato production in Sub-Sahara Africa. It focuses on gender, environmental factors, food security. The data and information used were collected using both qualitative and quantitativ...

The displacement in east Africa of the US‐1 clonal lineage of Phytophthora infestans by 2_A1 clonal lineage has been very rapid. This study tested the hypothesis that dominance of 2_A1 could be due, at least in part, to the increased aggressiveness of 2_A1 over US‐1, using both a detached leaf as...

Considered responsible for one million deaths in Ireland and widespread famine in the European continent during the 1840s, late blight, caused by Phytophthora infestans, remains the most devastating disease of potato (Solanum tuberosum L.) with about 15%–30% annual yield loss in sub‐Saharan Afric...

Fingerprinting of about 1,700 potato landraces and varieties using 207 simple sequence repeat (SSR) markers led us to identify a group of 24 SSR markers which constitute the potato genetic identity kit used for genetic resource characterization. These markers were selected for single locus, highl...

Partial root-zone drying (PRD) is an irrigation technique which consists of alternating the water supply from one furrow to another, and keeping the other one dry during the weekly alternation period. Studies assessing PRD in potato have reported a 30-50% of water savings with no tuber yield redu...

An attempt was made to introduce potato (Solanum tuberosum L.) in hot arid water scarce zone of Western Rajasthan, India. Eight CIP-bred potato clones were evaluated along with two controls, viz. Kufri Pukhraj and Kufri Surya on farmer’s field at Jodhpur, Rajasthan under normal and moderate water...

Integrated pest management (IPM) versus farmers’ pest management practices were evaluated in potato (Solanum tuberosum L.) in the central coast of Peru. IPM technologies consisted of seed treatment, insect pest, and disease scouting using action thresholds for decision making to apply pesticides,...

Cryopreservation protocols have been successfully developed for hundreds of species and thousands of genotypes in laboratories around the world. In many of the protocols, the rewarming process occurs in a rewarming solution (RS) with a high concentration of sucrose (0.8–1.2 M). Warming rate and a...
