Societal Costs of Late Blight in Potato and Prospects of Durable Resistance Through Cisgenic Modification
A case arguing for an updating and refinement of these rules in order to place cisgenic GM-crops in another class of GM-plants as has been done in the past with (induced) mutation breeding and the use of protoplast fusion between crossable species is presented. Expand
Applied Biotechnology to Combat Late Blight in Potato Caused by Phytophthora Infestans
It is envisioned that this CM approach with potato’s own genes will not only prove societally acceptable but may also result in simplifications in the legislation on use of the CM approach, based on cisgenic modification consisting of marker-free pyramiding of several resistance genes and their spatial and temporal deployment yielding dynamic varieties that contain potato genes only.

Ecology of potato cropping systems in relation to latitude and altitude.
- A. Haverkort
Abstract In this review the climate as affected by latitude from 0 to 50° N and altitude above sea level is described in relation to potato cultivation for the area between 20° W and 50° E. The… Expand
Potato prospects for Ethiopia: on the road to value addition
Nitrogen fertilization and row width affect self-thinning and productivity of fibre hemp (Cannabis sativa L.).
Investigation of agronomic factors in fibre hemp found inter-plant competition may cause self-thinning, which reduces stem yield and quality, and the crop growth at 80 kg N ha −1 was affected by a lack of nitrogen. Expand
Modelling development and growth of the potato crop influenced by temperature and daylength: LINTUL-POTATO.
The model can be used to simulate tuber dry matter production in specific environments and to select cultivars for such environments with suitable temperature and daylength reactions on tuber initiation and dry matter partitioning so as to maximise yields. Expand
Comparison of the growth of potato crops grown in autumn and spring in North Africa
The relationships between intercepted solar radiation and dry matter production (total and tubers) were established for four cultivars of different maturity classes and using seed tubers of two physiological ages in Tunisia, finding that tuber dry matter, number of stems per plant, tubers per stem and harvest indices were lower in the autumn than in the spring. Expand
Yield levels of potato crops: Recent achievements and future prospects
Abstract The potential yield of potato is defined as the theoretical yield that can be assessed for a well-adapted cultivar, grown from the best possible seed under optimal conditions. More than in… Expand
Climate Change and Its Repercussions for the Potato Supply Chain
Since the onset of the industrial revolution, in 1750, the concentration of carbon dioxide rose from 290 to 380 parts per million. Especially during the last decennia, the effects of increased… Expand
Yield Gaps and Ecological Footprints of Potato Production Systems in Chile
In Chile, potatoes are grown in a wide range of ecological zones and levels of technology resulting in wide ranges of crop management and yields. The aim of the present study was to assess yield… Expand
