Recognizing both the stakes of traditional European common bean diversity and the role farmers’ and gardeners’ networks play in maintaining this diversity, the present study examines the role that local adaptation plays for the management of common bean diversity in situ. To the purpose, four historical bean varieties and one modern control were multiplied on two organic farms for three growing seasons. The fifteen resulting populations, the initial ones and two populations of each variety obtained after the three years of multiplication, were then grown in a common garden. Twenty-two Simple Sequence Repeat (SSR) markers and 13 phenotypic traits were assessed. In total, 68.2% of tested markers were polymorphic and a total of 66 different alleles were identified. FST analysis showed that the genetic composition of two varieties multiplied in different environments changed. At the phenotypic level, differences were observed in flowering date and leaf length. Results indicate that three years of multiplication suffice for local adaptation to occur. The spatial dynamics of genetic and phenotypic bean diversity imply that the maintenance of diversity should be considered at the scale of the network, rather than individual farms and gardens. The microevolution of bean populations within networks of gardens and farms emerges as a research perspective.

“…Both “days to flowering” [25,34,35] and leaf size [36,37] are considered as indicators of local adaptation. Earlier flowering and earlier maturity in populations multiplied in LUX corresponds with a shorter growing season.…”

“…This heterozygosity makes their seed unsuitable for saving and replanting. In contrast, OP varieties consist of more diverse genetic populations and can be resown (Serpolay et al 2011). Advantages of hybrid varieties include the potential for improved crop uniformity and performance and for faster variety stabilization and release.…”

Plant breeding and seed issues are of growing importance in organic farming, but more regionally specific information is needed. In 2012, we surveyed Wisconsin organic vegetable growers regarding: a) general characteristics and farm practices; b) challenges in accessing organic seed; c) plant breeding priorities; and d) improving access to appropriate plant breeding and seed systems. Results suggest that growers had more difficulty accessing satisfactory genetics than seed quality, and that seed access was more problematic for growers with larger farming operations. Diverse plant breeding priorities, combined with prevalent variety trialing and seed saving, suggest a good fit with participatory plant breeding.

“…For instance in Austria, Canada, France, Germany, Switzerland, and USA organic winter wheat breeding programs have been initiated [27,70]. Projects in PPB for OF have also been established in tomato [71,72], cauliflowers [73], and Lolium [74], while there are other OPB undertakings for cabbage, broccoli [27], and onion [75] in The Netherlands or spinach in France [76].…”

The role of both organic (OF) and conventional (CF) farming remains open to debate particularly when related to food security and climate change. Targeting plant breeding for OF can contribute to reduce its yield gaps vis-à-vis CF. Currently, the cultivars produced for CF are also used in OF, however, it is unreasonable that all lines bred for CF will always perform well in OF. Nonetheless, plant breeding goals for OF and CF converge at aiming for high productivity, host plant resistance or tolerance to biotic and abiotic factors, and high resource-use efficiency. Likewise end-use quality and local adaptation may be more important for OF as the resource recycling and quality of the inputs that are used vary from region to region, even though OF practices are highly regulated. This article provides an overview on organic plant breeding (OPB) with a perspective from conventional plant breeding, highlights the main traits, their source of variation, and what methods and tools are available for their breeding. It concludes listing some organic crop breeding achievements and providing an outlook on what needs to be done for OPB.
