Abstract
Introducing new plants to an area may have both positive and negative effects on the environment, economy and community. To minimise the negative environmental impact of introducing new agricultural species, DPIRD conducts a risk assessment procedure based on widely accepted scientific standards. This report assesses Vigna unguiculata (cowpea). Vigna unguiculata (cowpea) originates from West Africa (Cook et al. 2020) with an additional centre of genetic diversity in Southern India (Krishna 2014). Ba et al. (2004) found that domesticated cowpea showed a high genetic variability. Combined with high morphological diversity this has resulted in a complex taxonomy which has been reviewed and reported by many authors. Krishna (2014) divides cowpea Vigna unguiculata into four sub species (cylindrica – Catjang bean; dekindtiana – black eyed bean; psesquipedalis – Yardlong bean and unguiculata – Southern peas). The commercially available varieties are var. unguiculata.
