Winter squash ( Duchesne.) is a vegetable of high socioeconomic importance owing to the nutritional quality of its fruits, seeds, and seed oil. This study aims to review the main aspects related to the characterization, conservation, and breeding of , emphasizing the studies with accessions maintained by the Vegetable Germplasm Bank of the Federal University of Viçosa (BGH-UFV). Studies on germplasm have reported high variability, particularly in Brazil. Currently, Brazil maintains six germplasm collections, kept in research and teaching institutions. The BGH-UFV collection, one of the largest in the country, contains approximately 350 accessions of , mostly landraces collected from all over Brazil. Studies characterizing this germplasm have identified promising genotypes as sources of alleles for increasing the carotenoid content in the fruit pulp and oleic acid content in the seed oil. As part of a breeding program to increase seed oil productivity and improve the oil profile, studies with the BGH-UFV germplasm have identified genotypes with seed oil productivity of up to 0.27 t ha and accessions producing oil with high oleic acid content (21 to 28%). The genetic breeding program of conducted at the UFV has prioritized the development of compact growth habit genotypes to reduce plant spacing and increase seed and oil productivity. The works involving the collection of maintained by the BGH-UFV corroborates the importance of this germplasm as a source of alleles for improving seed oil productivity and the oil profile.
南瓜（杜申南瓜）是一种具有高度社会经济重要性的蔬菜，因其果实、种子和种子油的营养品质。本研究旨在综述与南瓜的特征描述、保存和育种相关的主要方面，重点介绍对由维索萨联邦大学蔬菜种质库（BGH-UFV）保存的南瓜种质进行的研究。关于南瓜种质的研究报告了其具有高度变异性，特别是在巴西。目前，巴西保存了六个南瓜种质收集品，保存在研究和教学机构中。BGH-UFV收集品是该国最大的收集品之一，包含约350份南瓜种质，大多是从巴西各地收集的地方品种。对该种质进行特征描述的研究已确定有前景的基因型作为增加果肉中类胡萝卜素含量和种子油中油酸含量的等位基因来源。作为提高种子油生产力和改善油质的育种计划的一部分，对BGH-UFV种质的研究已确定种子油生产力高达0.27吨/公顷的基因型以及生产高油酸含量（21%至28%）油的种质。在UFV进行的南瓜遗传育种计划将紧凑型生长习性基因型的开发作为优先事项，以减少植株间距并提高种子和油的生产力。涉及BGH-UFV保存的南瓜种质收集的工作证实了该种质作为改善种子油生产力和油质的等位基因来源的重要性。
