Organic Farming and Small-Scale Farmers: Main Opportunities and Challenges (2017, background): “Nevertheless, the FAO, in a broad definition, considers lands 53 around the world that are smaller than 2 (ha) as small-scale farms.”
Decentralized selection and participatory approaches in plant breeding for low-input systems (2008, background): “DiVerences in system management, such as organic or conventional practices, can also result in crossover G£E interactions, and lines selected in one system and grown in another will not be as optimal as lines selected in the target system (Murphy et al. 2007).”
The need to breed crop varieties suitable for organic farming, using wheat, tomato and broccoli as examples: A review (2011, background): “However, this is ot necessarily the case for quantitative traits characterized by high enotype × environment interactions, like grain yield or end-use uality traits [5,16,182].”
Synthesis, part of a Special Feature on A Social-Ecological Analysis of Diversified Farming Systems: Benefits, Costs, Obstacles, and Enabling Policy Frameworks Ecosystem Services in Biologically Diversified versus Conventional Farming Systems: Benefits, Externalities, and Trade-Offs (2012, background): “…may negatively affect nutrient use efficiency, tolerance for mechanical weed control, pest resistance and crop nutrition, thereby reducing crop yield in organic systems (Murphy et al. 2007, Lammerts van Bueren et al. 2011) and contributing to the reported organic to conventional yield gap.”
Annual intercrops: an alternative pathway for sustainable agriculture. (2011, background): “Nowadays, organic farmers still depend mainly on modern varieties developed from conventional breeding programs (Murphy et al., 2007; Vlachostergios and Roupakias, 2008; Vlachostergios et al., 2010), but the majority of these varieties cannot face up efficiently problems as pest and fungus…”
Developments in breeding cereals for organic agriculture (2008, neutral): “OPB uses exclusively organic conditions and can be referred to as direct selection (see Murphy et al. 2007).”
Comparing the performance of cereal varieties in organic and non-organic cropping systems in different European countries (2008, background): “Murphy et al. (2007) compared 35 soft winter wheat breeding lines at five pairs (organic, non-organic) of sites during 2 years in Washington State, USA.”
The crop yield gap between organic and conventional agriculture (2012, background): “Murphy et al. (2007) showed that varieties used in conventional agriculture are not always the highest yielding varieties in organic systems, something also proposed by Wolfe et al. (2008).”
Crop Breeding for Low Input Agriculture: A Sustainable Response to Feed a Growing World Population (2011, background): “It has been shown that the most efficient way to improve yields under low-input conditions is to select varieties while under low-input or stress conditions [36].”
A Sustainable Agricultural Future Relies on the Transition to Organic Agroecological Pest Management (2018, background): “By investing in plant breeding for organic systems, we can develop cultivars that perform best in organic environments [63–66]; direct selection in organic systems can increase the yield by 30% or more compared with conventionally bred cultivars [63].”
