Cowpea [Vigna unguiculata (L.) Walp.] is a popular tropical grain legume which is widely produced and consumed in sub-Saharan Africa (SSA). The grains are rich in dietary protein for human while the haulm is high quality fodder for livestock particularly ruminants. Compared with many other crops cowpea is a laggard in development, evaluation and deployment of different molecular markers for use in genetics and breeding. Application of DNA-based markers is of considerable significance to crop improvement. Some DNA based markers have been used to study genetic diversity, linkage and quantitative traits loci (QTL) mapping in cowpea. Results from these studies have demonstrated the extent of genetic diversity in cowpea and its relationship with other members of the Vigna species. In addition, genetic linkage maps have been produced and used for detection of QTLs for some desirable traits. Some of these include QTLs for seed size, seed coat and eye color, leaf shape, pod length, resistance to macrophomina, domestication-related traits such as pod length, days to flowering, etc. In view of the potential benefits of DNA markers to the development of better performing improved cowpea varieties, concerted efforts are now being devoted to develop molecular tools for the crop. The developed consensus genetic linkage map and genome sequence for cowpea will boost the application of molecular tools for its genetic improvement. A panel of 17 SNP markers have been developed for use in quality assurance and control in cowpea breeding activities. This review aims at highlighting the molecular approaches that have been used and being pursued for genetic diversity, QTL mapping of some qualitative and quantitative traits as well as marker-assisted selection leading to the development of high performing new improved lines that meet the needs of farmers and consumers.

“…In addition, other factors such as the growing environment of cloves also influence. Phenotypic differences among plant accessions are influenced by genetic factors and strongly influenced by environmental conditions where they grow (Adu et al 2021;Ji et al 2021;Luong et al 2021;Tesfaye 2021).…”

Abstract. Mahulette AS, Alfian A, Suyadi, Supriyanto, Situmorang J, Matatula AJ, Kilkoda AK, Nendissa JI, Wattimena AY. 2022. Type and morphological character of local clove (Syzygium aromaticum) from Maluku, Indonesia. Biodiversitas 23: 1301-1309. Maluku Islands are known as the origin for the distribution of cloves (Syzygium aromaticum L.) in the world, where the diversity of clove germplasm is high. So far, information on the diversity of local clove morphology in Maluku is still very limited. The study was aimed to characterize the morphological diversity of local clove accessions in Maluku. The study was conducted in three distribution areas in Maluku, namely Ambon Island, Seram Island, and Haruku Island. Characterization was carried out on 130 local clove accessions of Maluku based on 32 morphological characters. The exploration identified nine types of cloves, namely Tuni, Forest Clove, Raja, Boiselang, Zanzibar, Bogor, Jinten, Tae, Damar, and three variants of Forest Clove, two variants of Raja, and two variants Zanzibar. Forest cloves, Raja, Boiselang Jinten, Tae, Damar are classified as wild-type cloves, while Tuni, Zanzibar and Bogor cloves are classified as cultivated cloves. The Hierarchical Cluster Analysis (HCA) obtained 2 large groups of local cloves with 57% agro-morphological differences. The first group is Forest Clove and Boiselang, while the second group is other local clove accessions (Tuni, Jinten, Red Zanzibar, White Zanzibar, Bogor, Damar, Tae, and Raja). The Principle Component Analysis (PCA) shows a total diversity of 66.7% with 4 characters based on grouping. These cloves are also categorized into wild type, cultivated, aromatic, and non-aromatic types.

“…Cowpea also ensures the sustainability of production systems, thanks to its rapid soil cover. It protects the soil from erosion and weed invasion, and restores its fertility (Alemu et al, 2016;Das et al, 2018;Adu et al, 2021). It is also climate-resistant and helps to maintain sustainable agriculture.…”

The genetic diversity of a genetic resource is an indicator of its richness and offers many possibilities for improvement. Cowpea is an important source of nutrients for humans and animals. This study aimed at assessing genetic diversity and relationships present among 135 accessions in the Centre National de Recherches Agronomiques (CNRA) collection, using qualitative traits. Traits analysis revealed significant genetic variation between the studied accessions through high Shannon diversity index. Estimated for 15 morphological characters with 0.80 mean value, H' ranged from 0.55 to 1. Seed traits generally expressed mean high diversity index (0.70-0.89). Between 15 parameters assessed, 12 exhibited the most discriminating variability of collection. The three MCA factorial axes explained 19.085% of phenotypic variability. The trait seed colour being correlated to these axes could be used as a selection criterion for local cowpeas improvement. Based on MCA and HAC methods, these accessions were classified into three distinct groups. Containing most accessions, subgroup Ia includes all seeds, pod, and flower colours. Almost all accessions of subgroup Ib possessed creamcoloured, smooth and globose seeds. All cluster II accessions have a creeping habit. The CNRA collection being very diversified, it constitutes a useful resource for future cowpea improvement studies in Côte d'Ivoire.
