“…For instance, introgression from the wild tomato L. esculentum var. cerasiforme to tomato L. esculentum has been detected in Cuba [58,59], resulting in interesting variation, including intermediate forms valuable for plant breeding because of fruit characters or disease tolerance. In maize (Zea mays), introgressive hybridization and further selection of races have been shown to be common events in the contemporary maize evolution in Cuba [60].…”

Plant genetic resources provide the basis for sustainable agricultural production, adaptation to climate change, and economic development. Many present crop plants are endangered due to extreme environmental conditions induced by climate change or due to the use of a limited selection of plant materials. Changing environmental conditions are a challenge for plant production and food security, emphasizing the urgent need for access to a wider range of plant genetic resources than what are utilized today, for breeding novel crop varieties capable of resilience and adaptation to climate change and other environmental challenges. Besides large-scale agricultural production, it is important to recognize that home gardens have been an integral component of family farming and local food systems for centuries. It is remarkable how home gardens have allowed the adaptation and domestication of plants to extreme or specific ecological conditions, thus contributing to the diversification of cultivated plants. Home gardens can help in reducing hunger and malnutrition and improve food security. In addition, they provide opportunities to broaden the base of cultivated plant materials by harboring underutilized crop plants and crop wild relative species. Crop wild relatives contain a wide range of genetic diversity not available in cultivated crops. Although the importance of home gardens in conserving plant genetic resources is well recognized, there is a risk that local genetic diversity will be lost if traditional plant materials are replaced by high-yielding modern cultivars. This paper provides an overview of home gardens and their present role and future potential in conserving and utilizing plant genetic resources and enhancing food and nutritional security under global challenges.

The cultivated races of Vigna SAVI in Cuba

The cultivated species of the genus Vigna in Cuba have been studied on the basis of living material collected during recent missions and herbarium material. The highest variability was found in Vigna unguiculata subsp. unguiculata. Probably this race has been early introduced by the Spaniards to Cuba. Later on several species were introduced by east Asiatic immigrants. Introgression and adaptation are considered as the main causes for building up a pronounced infraspecific variation in Vigna unguiculata. A key for the cultivated species is provided.
