Assessment of new potato cultivars in Europe: a survey

Abstract

SummaryIn 1994, a postal questionnaire was sent to 41 institutes in 27 countries to obtain information on the national potato cultivar testing programmes in Europe. Responses were received from 19 countries.Foliage, tuber and yield characteristics were assessed in all countries but the number of sites and replicates varied considerably between the countries. Cooking and taste qualities were measured in most countries using relatively simple methods but processing characteristics were tested less commonly. Susceptibility to the most common diseases, i.e. late blight, common scab, leafroll and PVY ~ was assessed in over 75% of the countries while resistance to another 21 diseases and 4 potato cyst nematode pathotypes was assessed by various countries, depending on their national importance. Many of the assessments were based on records of natural infection although controlled inoculation tests were done more frequently for the more important diseases.

Identifying Resistance to the Colorado Potato Beetle (Leptinotarsa decemlineata Say) in Potato Germplasm: Review Update

“…Chemical control has been largely studied (Grafius, 1995(Grafius, , 1997Wustman and Carnegie, 2000;Zabel et al, 2002;Stankovik et al, 2004;Alyokhin et al, 2008;Grafius and Douches, 2008;Alyokhin, 2009;Sladam et al, 2012;Szendrei et al, 2012;Piiroinen et al, 2014;Clements et al, 2016). Although insecticides are effective, resistance has been an issue in many populations (Casagrande, 1987;Kennedy and Farrar, 1987;Helm et al, 1990;Grapputo et al, 2005;Alyokhin et al, 2006Alyokhin et al, , 2008Szendrei et al, 2012;Kaplanoglu et al, 2017;Clements et al, 2018;Crossley et al, 2018), while other populations have largely remained susceptible to insecticides (Haegele and Wakeland, 1932;Johnston and Sandvol, 1986;Olson et al, 2000;Alyokhin et al, 2015;Crossley et al, 2018;Dively et al, 2020).…”

Managing the Colorado potato beetle; the need for resistance breeding

“…It is expected that the CPB will develop resistance to all new insecticides deployed. Besides that, large scale application of chemical pesticides can lead to serious health and environmental problems (Wustman and Carnegie 2000;Alyokhin 2009). As a result, there is an increasing public demand for reduction of pesticide use and withdrawal of certain chemical compounds because of their harmful effects on growers, consumers, and the environment (Dik et al 2000).…”
