Breeding Late Blight Resistant Potatoes for Organic Farming—a Collaborative Model of Participatory Plant Breeding: the Bioimpuls Project

Development of late blight resistant potatoes by cisgene stacking

BACKGROUND Phytophthora infestans, causing late blight in potato, remains one of the most devastating pathogens in potato production and late blight resistance is a top priority in potato breeding. The introduction of multiple resistance (R) genes with different spectra from crossable species into potato varieties is required. Cisgenesis is a promising approach that introduces native genes from...

Farmer Plant Breeding from a Biological Perspective: Implications for Collaborative Plant Breeding

Plant breeding by researchers has become increasingly isolated from the plant breeding of farmers. Collaborative plant breeding (CPB) offers the possibility of bringing these two plant breeding traditions together to increase the usefulness of new crop varieties to farmers, especially small-scale farmers working in stress environments with limited external inputs. This paper presents a framewor...

Advantages and Disadvantages of Participatory Plant Breeding (PPB) in Iran: A Study Based on Breeders' Perceptions

The purpose of this study was to investigate the advantages and disadvantages of Participatory Plant Breeding (PPB). Seventy-six breeders were randomly selected from among 95 breeders who were working at the Seed and Plant Improvement Institute, Karaj, Iran. Data were collected by a questionnaire as the main data collection instrument. The face and content validity of the questionnaire was appr...

Crossing Perspectives Farmers and Scientists in Participatory Plant Breeding

Concepts and Strategies of Organic Plant Breeding in Light of Novel Breeding Techniques

In this paper, we describe the development of a set of guiding principles for the evaluation of breeding techniques by the organic sector over time. The worldwide standards of organic agriculture (OA) do not allow genetic engineering (GE) or any products derived from genetic engineering. The standards in OA are an expression of the underlying principles of health, ecology, fairness and care. Th...
