非洲本土蔬菜品种为乌干达许多城市和城郊居民提供了生计手段。因此，认为有必要了解传统非洲蔬菜物种的现有多样性和分布情况，以此为基础提出保护和利用战略，防止生物多样性丧失。在乌干达的四个主要农业生态区进行了实地调查，以提供关于各种人工植被和植物最近丰富程度的资料。调查结果表明，在所遇到的7个不同科中，茄科（43.4%）、苋科（15.5%）和锦葵科（11.6%）是最常见的科。确定了23个物种，数量低于文献中最初报告的数量，并且在不同地区的分布不均匀。大部分的物种是本地的，而不是引进的蔬菜品种。首先，该研究提供了与其他AIVS相比茄科物种的上级重要性的信息。其次，调查结果表明，AIVS在乌干达变得越来越重要，因为所有的43.4%，构成茄科多数是土著类型。研究工作应致力于改进品种开发和种质保存，以防止最重要的人工免疫和植物检疫系统的生物多样性可能丧失，从而增加乌干达和其他撒哈拉以南非洲国家资源贫乏的大多数人的家庭收入和营养安全。
African indigenous vegetable species (AIVS) provide a means of livelihood to many urban and peri-urban dwellers in Uganda. It was thus deemed necessary to understand the existing diversity and distribution of the traditional African vegetable species as a basis for recommending conservation and utilization strategies against biodiversity loss. A field survey was conducted in the four major agro-ecological zones of Uganda to provide information on a recent abundance of the various AIVS. Results from the survey showed that the Solanaceae (43.4%), Amaranthaceae (15.5%) and Malvaceae (11.6%) were the most prevalent families out of seven different families encountered. Twenty-three (23) species, a number lower than that initially reported in literature and distributed unevenly in the different regions were identified. Majority of the species were the indigenous rather than introduced vegetable species. Firstly, the study is informative of the superior importance of Solanaceous species compared to other AIVS. Secondly, the survey results indicate that the AIVS are becoming increasingly more important in Uganda than their introduced counterparts since all the 43.4% that composed the Solanaceae majority were of indigenous type. Research efforts should be devoted towards improved variety development and germplasm conservation to prevent a possible biodiversity loss of the most important AIVS for increased household incomes and nutrient security among the resource-poor majority in Uganda and other sub-Saharan Africa countries.
