“…Quality traits should also be given priority for OPB: micronutrient content and plant growing and storage as they can influence grain quality [90]. Traits for low-input farming systems such as increased N-uptake and N-use [91][92][93][94] and enhanced competing ability against pathogens and weeds [95,96] will be also important for OPB.…”

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.

“…Moreover, yellow or black grains are preferred in some areas (Serna-Saldivar et al 2001;Landa et al 2006). Actually, in previous studies we concluded that differences in pigment content are directly related to antioxidant activity in maize grains and that traditional methods for maize production and processing maintained quality, pigment content and antioxidant activity (Revilla et al 2012;Rodríguez et al,. 2013).…”

Breeding maize (Zea mays L.) for traditional agriculture can increase quality and added value of agricultural products and allow the recovery of traditional foods. The objectives of this work were to evaluate improved open-pollinated populations under organic and conventional agriculture in order to determine the effects of selection for yield and flour yield and the relationship between agronomic and quality traits under both cropping systems. We have selected open-pollinated maize populations for flour yield and bakery quality under organic conditions, improved them under conventional conditions and evaluated the breeding programs under organic and conventional conditions. Breeding was efficient for grain and flour yield under organic agriculture for Meiro (an open-pollinated population with black grains) but not for the other populations neither in organic nor in conventional conditions. Yield ranks of varieties were moderately correlated under both conditions, and genotype  environment interaction (GE) was significant for most traits when the analyses of variance were made over all environments but also when organic and conventional environments were separated. GE was higher under organic agriculture.Correlations between traits were higher under conventional agriculture and there were important discrepancies between correlations in organic and conventional agriculture. We concluded that selection under conventional agriculture was efficient for one population under organic agriculture. Selection under the target environment could increase the possibilities of success.

“…Additionally, the market demand for gluten-free formulations has driven more research in the different steps leading from the maize kernel to the maize bread quality (e.g., Moreira et al, 2015 ; Garzón et al, 2017 ; Martínez and Gómez, 2017 ). In parallel, an increased investment on the improvement of open-pollinated maize populations has been driven by a renewed interest in materials traditionally used for ethnic food commodities and for their use in the context of more sustainable farming systems (e.g., Revilla et al, 2012 , 2015 ; Samayoa et al, 2016 ).…”

Setting Up Decision-Making Tools toward a Quality-Oriented Participatory Maize Breeding Program

et al. 2017

Previous studies have reported promising differences in the quality of kernels from farmers' maize populations collected in a Portuguese region known to produce maize-based bread. However, several limitations have been identified in the previous characterizations of those populations, such as a limited set of quality traits accessed and a missing accurate agronomic performance evaluation. The objectives of this study were to perform a more detailed quality characterization of Portuguese farmers' maize populations; to estimate their agronomic performance in a broader range of environments; and to integrate quality, agronomic, and molecular data in the setting up of decision-making tools for the establishment of a quality-oriented participatory maize breeding program. Sixteen farmers' maize populations, together with 10 other maize populations chosen for comparison purposes, were multiplied in a common-garden experiment for quality evaluation. Flour obtained from each population was used to study kernel composition (protein, fat, fiber), flour's pasting behavior, and bioactive compound levels (carotenoids, tocopherols, phenolic compounds). These maize populations were evaluated for grain yield and ear weight in nine locations across Portugal; the populations' adaptability and stability were evaluated using additive main effects and multiplication interaction (AMMI) model analysis. The phenotypic characterization of each population was complemented with a molecular characterization, in which 30 individuals per population were genotyped with 20 microsatellites. Almost all farmers' populations were clustered into the same quality-group characterized by high levels of protein and fiber, low levels of carotenoids, volatile aldehydes, α- and δ-tocopherols, and breakdown viscosity. Within this quality-group, variability on particular quality traits (color and some bioactive compounds) could still be found. Regarding the agronomic performance, farmers' maize populations had low, but considerably stable, grain yields across the tested environments. As for their genetic diversity, each farmers' population was genetically heterogeneous; nonetheless, all farmers' populations were distinct from each other's. In conclusion, and taking into consideration different quality improvement objectives, the integration of the data generated within this study allowed the outline and exploration of alternative directions for future breeding activities. As a consequence, more informed choices will optimize the use of the resources available and improve the efficiency of participatory breeding activities.
