While crop genetic diversity supports ecological processes and food security, there have been few cross-cultural studies evaluating the influence of cultural and dietary factors on the conservation of genetic resources. This study examines genetic diversity patterns of tartary buckwheat in 18 smallholder farming communities across five regions of China (Yunnan Province, Tibet Autonomous Region and Sichuan Province) and Bhutan managed by Yi, Tibetan, and Bhutanese farmers using ethnobotanical surveys and DNA barcoding. Findings emphasize that high dietary dependence linked to a single crop may result in simplification of genetic diversity as well as agricultural systems and landscapes more broadly. We advocate for the diversification of crops in agricultural systems as well as diets through the integration of scientific research and farmers' ecological knowledge and practices towards meeting global food security while supporting environmental well-being through biodiversity conservation.

“…Besides this, the three forms of broad bean germplasm conservation reported by Duc et al (2010), clearly predominate in the comunidades, en Tlachichuca equina es la que mayormente se siembra (Figura 7). Destaca la comunidad de San José con alrededor de 85% de haba mayor utilizada para la siembra.…”

“…Aunado a lo anterior, de las tres formas de conservación del germoplasma de haba reportadas por Duc et al (2010), en el país predominan claramente las poblaciones, que se caracterizan como las de mayor variabilidad y es prácticamente la única forma en que la mantienen los productores. Por lo tanto, se cuenta con una gama de posibilidades en variantes de los caracteres, que deben ser aprovechados en el mejoramiento de las características que demandan los agricultores.…”

El objetivo de la investigación fue conocer la tecnología aplicada al cultivo de haba, para la producción de grano en diferentes comunidades de Puebla y Tlaxcala, México; con la f inalidad de encontrar las prácticas débiles y las características socioeconómicas esenciales; así como, los caracteres deseables por los productores de una variedad de haba. El trabajo se desarrolló en la región productora de haba en México. Se aplicaron 100 cuestionarios, 20 por comunidad y una entrevista semiestructurada a informantes clave más información de los agricultores, mediante observaciones directas. Predominan los productores con rasgos de campesinado tradicional en el uso de la tecnología de producción de haba, basada en herramientas tradicionales y el uso de animales de trabajo en la preparación del terreno. La fuente de semillas para la siembra, son las variedades locales que ellos siembran año con año. Entre las características socioeconómicas destacan, que 4% es del sexo femenino y la edad promedio es de 49 años. La región productora de haba cuenta con una combinación de productores, con diferentes grados de campesinidad alternado con productores comerciales o en transición de serlo. Los caracteres de interés deseados por sus variedades, son tamaño de semilla grande o mediana, abundantes en flores, vainas y semillas, que sean precoces y resistentes a las principales plagas, enfermedades y sequía.

“…III and IV were integrated by accessions P25 and P29, respectively from Santiago Tianguistenco and Metepec; this indicates these accessions were significantly different at molecular level in relation to all the accessions. The genetic variability observed in accession P25 can be related to a differential response to biotic or abiotic stress, to the agronomic management or else to its facility to adapt to other environments, as it is commented by Duc et al (2010), variability can be the result from such factors. As for accession P29, it is one of the varieties generated by ICAMEX (2004).…”

“…However, in recent decades the production has noticeably decreased, mainly due to conditions of biotic and abiotic stress, so it is necessary to generate materials that counteract side effects; to do so, it is necessary to learn the degree of diversity and relation between accessions by means of characterization, not only agromorphological but also at molecular level, which in our country is incipient and necessary. Duc et al (2010) mention that at global level faba bean is only represented in herbarium collections and germplasm banks, so genetic resources represented through wild species, cultivated plants, local accessions, varieties, hybrid lines, and elite lines are important as gene sources. So when a germplasm, diversity and relationship between materials are unknown; characterization of genetic variability and selection of population are important in the efficiency of breeding programs (Alghamdi et al, 2012a).…”

Faba bean crop (Vicia faba L.) is important in Mexico, it is a legume rich in protein and its market price is higher than those of maize and bean; however, in recent years there has been a significant decline in its performance. The aim of this study was to determine the genetic variability and analyze the relationship between 39 faba bean accessions using inter simple sequence repeats (ISSR) markers. Accessions of faba bean were collected according to their best phenotypic characteristics, later they were molecularly characterized. With the obtained band registration, a binary data matrix was built to perform the corresponding statistical analysis. The utilized ISSR markers produced 142 fixed and repeatable bands, of which 134 were polymorphic. The values of resolution power (Rp), polymorphic information content (PIC), and marker index (MI), respectively indicated that primer 848 was the most efficient to analyze genetic variability with values of 12.8, 0.40, and 8.06, respectively, followed by primers 857 and ISSR2M. Genetic distances oscillated between 0.38 and 0.83, and verified the groupings observed in the dendrogram, which indicates high variability at the level of DNA among the analyzed genotypes, observing six defined groups according to UPGMA analysis. In the analysis of main components the registered groupings were determined by the origin of the gathering. The use of ISSR markers was efficient to characterize at the level of DNA the assessed bean accessions, indicating the existence of variability, the identified contrasting accessions can be utilized in genetic improvement programs aimed at solving the needs of the producers.
