This study provides insights in patterns of distribution of abiotic and biotic stress resilience across Vigna gene pools to enhance the use and conservation of these genetic resources for legume breeding. Vigna is a pantropical genus with more than 88 taxa including important crops such as V. radiata (mung bean) and V. unguiculata (cowpea). Our res...

Although new varieties are urgently needed for climate-smart legume production, legume breeding lags behind with cereals and underutilizes wild relatives. This paper provides insights in patterns of abiotic and biotic stress resilience of legume crops and wild relatives to enhance the use and conservation of these genetic resources for climate-smar...

The genus Capsicum (2n = 24) comprises a diverse group of plants producing pungent (hot pepper syn. chili pepper) or non-pungent (sweet pepper) fruits valued as spices and vegetables. The genus originated in the arid regions of the Andes mountains (present-day Peru and Bolivia) and later spread to the tropical lowlands of the Americas. The domestic...

Food legumes like mungbean (Vigna radiata var. radiata), black gram (Vigna mungo), and rice bean (Vigna umbellata) have potential to diversify diets and agro-ecosystems of the tropics. Access to genetic diversity and phenotypic data are key issues for crop improvement. Large germplasm collections like the one at the World Vegetable Center may be us...

Eggplant is the fifth most economically important solanaceous crop after potato, tomato, pepper, and tobacco. Apart from the well-known brinjal eggplant (Solanum melongena L.), two other under-utilized eggplant species, the scarlet eggplant (S. aethiopicum L.) and the gboma eggplant (S. macrocarpon L.) are also cultivated. The taxonomy and identifi...

Cleome gynandra L. is a leafy vegetable native to sub-Saharan Africa and Asia and cultivated on dry areas. The plant plays an important role in the food and nutrition security of local communities. The objective of this study was to illustrate variation and diversity in the Cleome collection held at the World Vegetable Center. In total, 242 accessi...

With about 84,300 accessions, the section Lycopersicon in the genus Solanum is well-represented in ex situ collections around the globe. The single largest collection (approximately 9.7% of total global resources) is held by AVRDC – The World Vegetable Center in Taiwan, followed by genebanks in the US, the Philippines, Germany, the Russian Federati...

Peppers (Capsicum spp.) with pungent (chili, hot pepper) and non-pungent (sweet pepper) fruits are important spice and vegetable crops worldwide. There are five domesticated species of the genus Capsicum, C. annuum being the most widely cultivated. Over the past 25 years, the pepper breeding program at AVRDC– The World Vegetable Center has focused...

Peppers (Capsicum spp.) are an important cash crop for smallholder farmers in developing countries. Hot pepper (chili) dominates world spice trade, and sweet pepper has become a popular vegetable and cash crop in the tropics for smallholders. Among the five cultivated species of the genus Capsicum, C. annuum (both hot and sweet pepper) is the most...
