Small radish and radish are economically important root crops that represent an integral part of a healthy human diet. The world collection of L. root crops, maintained in the VIR genebank, includes 2810 accessions from 75 countries around the world, of which 2800 (1600 small radish, 1200 radish) belong to species, three to , three to , and four to . It is necessary to systematically investigate the historical and modern gene pool of root-bearing plants of and provide new material for breeding. The material for our research was a set of small radish and radish accessions of various ecological groups and different geographical origin, fully covering the diversity of the species. The small radish subset included 149 accessions from 37 countries, belonging to 13 types of seven varieties of European and Chinese subspecies. The radish subset included 129 accessions from 21 countries, belonging to 18 types of 11 varieties of European, Chinese, and Japanese subspecies. As a result of the evaluation of accessions according to phenological, morphological, and biochemical analyses, a wide variation of these characteristics was revealed, which is due to the large genetic diversity of small radish and radish of various ecological and geographical origins. The investigation of the degree of variation regarding phenotypic and biochemical traits revealed adaptive stable and highly variable characteristics of accessions. Such insights are crucial for the establishment and further use of trait collections. Trait collections facilitate germplasm use and contribute significantly to the preservation of genetic diversity of the gene pool.
小萝卜和萝卜是具有重要经济价值的根茎类作物，是健康人类饮食中不可或缺的一部分。保存在全俄植物栽培研究所基因库中的世界萝卜属根茎类作物收集品包括来自世界75个国家的2810份种质，其中2800份（1600份小萝卜、1200份萝卜）属于萝卜属物种，3份属于其他属，3份属于其他属，4份属于其他属。有必要系统地研究萝卜属根茎类植物的历史和现代基因库，并为育种提供新材料。我们的研究材料是一组来自不同生态群体和不同地理来源的小萝卜和萝卜种质，充分涵盖了该物种的多样性。小萝卜子集包括来自37个国家的149份种质，属于欧洲和中国亚种7个变种的13个类型。萝卜子集包括来自21个国家的129份种质，属于欧洲、中国和日本亚种11个变种的18个类型。根据物候、形态和生化分析对种质进行评估的结果显示，这些特征存在广泛变异，这是由于不同生态和地理来源的小萝卜和萝卜具有较大的遗传多样性。对表型和生化性状变异程度的研究揭示了种质的适应性稳定和高度可变特征。这些见解对于性状收集品的建立和进一步利用至关重要。性状收集品有助于种质利用，并对基因库遗传多样性的保护做出重大贡献。
