Abstract

One of the challenges faced in the study of this genus is the ability to identify them when encountered in the field. This study was carried out to Compare morphological characteristics of a panel of twenty-two (22) Vigna savi of some cultivated(5) and wild(17) species obtained from the International Institute of Tropical Agriculture IITA, Ibadan Nigeria. Seeds were planted at the Department of Crop and Soil Science Research Farm, University of Port Harcourt, Nigeria using the experimental design Complete Randomized Block Design (CRBD). Physical observations were made on the seeds and the vegetative parts were observed for taxa delineation in the field. Results obtained showed the features that were of significance morphologically include the seed size, hilum position, plant height, leaf shape, leaf hairiness, twinning tendency, presence or absence of adventitious roots and the perennating stomps encountered in only one of the cultivated species of Vigna unguiculata (IT81D-975) amongst all others encountered in this study. The leaf shapes observed includes the ovate, lanceolate, cordate, elliptic, linear and deltoid. Variation in stem and petiole pigmentation at the germination phase and maturity were areas of variation indicating their phylogeny. The parameters employed in this result is to aid in providing good description for taxa separation. The relevance of these parameters in the taxonomic delimitation of species provides an easy means of identification when encountered in the field. The variations revealed morphologically could be exploited to improve passport data available for Vigna.
