“…A core collection (30 accessions) for Taiwanese vegetable soybeans have been described by Kao et al [ 92 ]. Historical data (1973–2015) collected at the World Vegetable Center were utilized for developing soybean core collections representing the diversity of the whole collection of 7853 accessions held by the center [ 93 ]. The collection was split into two groups by Nair et al [ 93 ] on the basis of the 100 seed weight: large seeded (> or equal to 25 g) and small seeded (<25 g).…”

Vegetable soybean, popularly known as edamame in Japan and mao dou in China is a specialty soybean. Green pods with physiologically mature beans are harvested, and whole pods or shelled beans are used as a fresh or frozen vegetable. Vegetable soybeans are prepared in diverse ways, and they are highly nutritious, with excellent taste properties. Unlike grain soybeans, it is perishable. In this review, the chronological progression of area, production, export, import, and expansion of vegetable soybeans and potential for further expansion is discussed. Available information on current ongoing research and development activities in various countries around the world are presented, and their relevance is discussed. At present, the production and consumption of vegetable soybeans are mainly in East and Southeast Asia, with Japan as the largest importing country that dictates the global market. However, interest and trend in cultivation of this crop in other regions has increased significantly. Lack of germplasm or suitable varieties is a major constraint in vegetable soybean production and expansion in countries outside East and Southeast Asia. Most of the vegetable soybean varieties are genetically related and are susceptible to biotic and abiotic stresses. Extensive research and breeding of vegetable soybeans are still restricted in a few countries such as China, Japan, Taiwan and the USA. The need for focused research and development activities with concern for the environment, farmers’ and processors’ profit, consumers’ preference, quality, and nutrition are emphasized.

Key message Hyperspectral features enable accurate classification of soybean seeds using linear discriminant analysis and GWAS for novel seed trait genes. Abstract Evaluating crop seed traits such as size, shape, and color is crucial for assessing seed quality and improving agricultural productivity. The introduction of the SUnSet toolbox, which employs hyperspectral sensor-derived image analysis, addresses this necessity. In a validation test involving 420 seed accessions from the Korean Soybean Core Collections, the pixel purity index algorithm identified seed- specific hyperspectral endmembers to facilitate segmentation. Various metrics extracted from ventral and lateral side images facilitated the categorization of seeds into three size groups and four shape groups. Additionally, quantitative RGB triplets representing seven seed coat colors, averaged reflectance spectra, and pigment indices were acquired. Machine learning models, trained on a dataset comprising 420 accession seeds and 199 predictors encompassing seed size, shape, and reflectance spectra, achieved accuracy rates of 95.8% for linear discriminant analysis model. Furthermore, a genome-wide association study utilizing hyperspectral features uncovered associations between seed traits and genes governing seed pigmentation and shapes. This comprehensive approach underscores the effectiveness of SUnSet in advancing precision agriculture through meticulous seed trait analysis.

“…A primary goal of the core collection is the effective utilization of available genetic resources (Odong et al., 2013; van Hintum et al., 2000). To date, several core collections have been developed from diverse crop taxa, including peanut (Holbrook et al., 1993), annual Medicago (Diwan et al., 1994), Capsicum (Zewdie et al., 2004), safflower (Dwivedi et al., 2005), pearl millet (Bhattacharjee et al., 2006), cowpea (Mahalakshmi et al., 2007), wild mustard (Zhao et al., 2010), rice (S. Kumar et al., 2020; H. Zhang et al., 2011), Australian bermudagrass (Jewell et al., 2012), cotton (Egan et al., 2022), soybeans (N. Jeong et al., 2019; Nair et al., 2022), and Brassica (Witzel et al., 2021). A core collection also provides opportunities for marker development, phytochemical profiling, and gene discovery.…”

Crop breeding programs are reliant on the genetic diversity of varieties and germplasm collections. Raphanus sativus L. is a root crop species of the Brassicaceae family that accounts for approximately 2% of global vegetable production. We recently reported the assembly of a new radish core collection consisting of 125 accessions obtained from worldwide germplasm banks. To develop a comprehensive plant resource for radish research and breeding, we characterized the agronomic traits of 83 accessions and analyzed their genome‐wide DNA variations along with 17 previously analyzed accessions. A total of 14 agronomically important root, leaf, and flower phenotypic traits were examined according to the guidelines of the International Union for the Protection of New Plant Varieties. Chemical diversity in radish roots was investigated by measuring their sugar, glucosinolate, and anthocyanin contents. Through high‐depth whole‐genome resequencing of 100 accessions and multi‐sample genotyping analysis using the Rs2.0 genome assembly as a reference, we identified a total of 796,294 homozygous high‐quality single‐nucleotide polymorphisms. Genetic structural analysis using a neighbor‐joining algorithm and multi‐dimensional scaling analysis of the variations were applied to classify the accessions into three major groups, including 37 and 55 accessions of European and Asian cultivated radishes, respectively, and 8 wild radish accessions. For each accession, the mitochondria‐encoded Ogura cytoplasmic male‐sterility determinant orf138 and nuclear fertility restorer PPR‐B genes were reconstructed by reference‐guided assembly. It is anticipated that these genetic diversity and agronomic properties of the radish core collection will facilitate breeding programs to develop new radish cultivars with desirable profiles.This article is protected by copyright.
