In the U.S., the largest market class of cowpea harvested as dried seed is black-eyed pea and pink-eyed/purple hull southern pea. The classification of a range of variability among acces-sions is pivotal to the maintenance and further acquisi-tion of germ plasma resources even as accessions from diverse origins are needed as parent stocks for the development of improved varieties. Cowpea [Vigna unguiculata (L.) Walp.] Experts agree that cowpeas belong to the botanical species Vigna unguiculata (L.) Walp.

This classification system is useful for characterizing the types of heat responses present in cowpea genotypes and for selecting appropriate combinations of parents for breeding heat‐tolerant cultivars for different production zones and seasons. Cowpea is one of the most ancient crops known to man. ( Vigna unguiculata ) Cowpea is a food and animal feed crop grown in the semi-arid tropics covering Africa, Asia, Europe, United States and Central and South America. Classification According to Botany 4. ), genetic variation is present for heat tolerance and responses to photoperiod during different stages of reproductive development. It is also known as dinawe (Ndebele), dinaba (Shangaan), imbumba (Zulu), monawa or nawa (Pedi) and dinawa (Tswana). The model developed through this method enabled the correct separation of the samples into the five cowpea varieties investigated, where 100% sensitivity was achieved for most of the predicted classes. The genotypes were classified into II groups based on photoperiod response (change in position of the first reproductive node or period to appearance of floral buds in long compared with short days), juvenility (minimum period for appearance of floral buds when grown under short days), and suppression of floral bud development and pod set under hot long days. Cowpea is primarily used in the form of dry seeds, fodder, green pod, green manure, and cover crops. The aim of our study was to define the taxono … Number of times cited according to CrossRef: Identification and Evaluation of Chickpea Germplasm for Tolerance to Heat Stress.
