... The observed high diversity of Lamiaceae taxa in Bulgarian rural home gardens should be attributed not only to the fact that nearly 70% of our participants cultivated two to four Lamiaceae taxa in their gardens, but also to the very high preference for local forms (landraces) of culinary herbs that were inherited from previous generations or obtained through informal exchange within their community. Utilization of local genetic resources for their local organoleptic perceptions and their perceived cultural value was previously shown to contribute to their in situ preservation, which creates additional opportunities for the development of local entrepreneurship [60,61]. Still, the relatively high age of the rural population in Bulgaria should be considered as an alarming factor in terms of the need for the development of targeted collection programs for the safeguarding of these resources [62]. ...
... The accelerated loss of biodiversity has caused growing concern, and even a significant extinction of species has been reported due to the consequences of climate change and land use [3]. For this reason, the design of strategies and programs for the knowledge, conservation, management, and sustainable use of biodiversity is important [4][5][6][7]. Cultivated plants have been mainly preserved through ex situ conservation in germplasm banks, whereas in situ conservation has been carried out in growers' farms to a lesser extent, and wild species have been mostly conserved in nature reserves [3,8]. ...

... Therefore, it is crucial for them to be able to respond to the varied conditions. Abiotic stresses in the shape of heat, salinity, chill, flood, water deficit, and heavy metals have a devastating impact on plant growth and yield [1][2][3][4][5]. Salinity is one of the most devastating environmental factors, magnified by the intensive salinization of lands [6]. Variable intensities of salt cause photosynthetic apparatus damage, nutritional insufficiency, oxidative injury, osmotic pressure, and ion toxicity [7,8], which interferes with all growth stages, comprising sprouting of seeds, seedling formation and fertility ratio [9]. ...
... Instead, ISA breeding lines exhibited a slightly lower branching degree than the Peruvian lines, but their yields were lower, ranging between 7 g/plant (LIB202) and 25.3 g/plant (LIB204). Following LIB204, LIB214 (23.3 g/plant), and LIB212 (21.5 g/plant) appear to be the best ISA accessions for this environment, confirming their good agronomic performance in previous studies (Guilengue et al., 2020;Lazaridi et al., 2020). Therefore, our results expand upon prior work, pointing out the possibility of improving the performance of already selected lines for Europe by making use of the high breeding potential of germplasm from Peru. ...

... Narrow endemic medicinal plants are constantly at the risk of extinction and destruction due to their limited geographical distribution and specific ecological growth conditions as well as management factors such as over harvesting and unprincipled harvests (7,8). Domestication of such valuable medicinal plants not only can help save them from extinction and overharvesting but also can help provide the pharmaceutical requirements by introducing the new varieties with desirable components (9). ...
... In recent years a considerable amount of scholarly literature (from various theoretical perspectives) on the EU's CAP has examined its impact on biodiversity (Cole et al. 2020), environmental impacts in general (Borrelli &Panos 2020), nutrition andhealth (Walls et al. 2016) and especially on the CAP reforms of the last two decades (Dermikol 2020; Barnes et al. 2016;Lovec 2016). Despite the abundance of research carried out on such aspects of the CAP, an actor-centred constructivist approach to analysing the policy's original preparation and creation has been largely neglected. ...
... Pearson correlation coefficients exhibited the significant statistical correlations among garlic genotypes either positive or negative (Table 5). Such a significant correlation was observed in many reports (Gehani and Kanbar, 2013;Fanaei et al., 2014;Akan, 2019;Ayed et al., 2019;Polyzos et al., 2019). According to the results, there were a strict correlation among bulb diameter, bulb weight, bulb height, clove height, and clove weight. ...
