Genus Abelmoschus Medik (family - Malvaceae Juss.) comprising about 11 species in India. Among which some are cultivated on an economic scale as important vegetables and the rest are wild. Apart from cultivated species, wild species of Abelmoschus also showed a wide range of phytochemicals and nutritional components. Abelmoschus esculentus (L.) Moench an economically important vegetable crop popularly known as okra which cultivated throughout the world. Nutritionally, okra plays an important role in the human diet because it has enormous value of nutritional factors like carbohydrates, protein, fibers, minerals and vitamins, including vitamin C. Mucilage obtained from Abelmoschus is natural and digestive in nature and used as a tablet binder. The plant shows various pharmacological activities like, antioxidants, antidiabetic, antiulcer and antimicrobial. Apart from cultivated species, the studies on wild species were carried out and concluded some important findings viz. Abelmoschus manihot (L.) Medik. is rich source of various secondary metabolites like; hyperin, isoquercetin, myricetin, hibifolin, adenosine and stigmasterol. Abelmoschus ficulneus (L.) Wight & Arn. and A. manihot are consumed by the local people worldwide. The present chapter is focused on the previous work done in genus Abelmoschus in the area of nutrition, phytochemical, genetic diversity and breeding.

“…Two okra species are important commercially: A. esculentus ("Indian okra, " responsible for 95% of global production) and A. callei ("African okra, " responsible for 5% of global production) (Kumar et al, 2010). An interesting feature of both species is their high chromosome number (2n = 130-200) associated with polyploidy (Ahiakpa et al, 2017). The genetic diversity of A. callei is located exclusively in West Africa (Figure 1), pointing to that region as the site of domestication (Figure 1), whereas A. esculentus landraces are located in Northern India (Uttar Pradesh), Africa and globally (Aladele et al, 2008;Kumar et al, 2010;Benchasri, 2012;Werner et al, 2016;Ahiakpa et al, 2017).…”

Therefore, the authentic site of A. esculentus domestication is disputed and requires further combined archaeological and genetic diversity evidence.…”

There is a general unawareness of food crops indigenous to the African continent that have contributed to Western culture. This under-appreciation is particularly relevant in the current context of societal movements to end historic racism and value the contributions of peoples of African origin and African skin colors. Lack of awareness of the contributions of Africa's crops has negative practical consequences, including inadequate investments in preserving and maximizing the use of crop diversity to facilitate breeding. This paper provides an overview and analysis of African crops that have made significant contributions to the United States and globally, and/or hold potential in the twenty-first century. The paper specifically discusses watermelon, coffee, kola, rooibos, oil palm, shea, cowpea/black eyed pea, leafy greens, okra, yam, sorghum, pearl millet, finger millet, teff, and fonio. The review focuses on the intersection of these crops with racialized peoples, with a particular focus on African-Americans starting with slavery. The analysis includes the sites of domestication of African crops, their historical migration out of Africa, their sociocultural contributions to cuisines and products around the world, their uses today, and the indigenous knowledge associated with traditional cultivation and landrace selection. The untapped potential of local genetic resources and indigenous agronomic strategies are also described. The review demonstrates that African crops played an important role in the development of American cuisine, beverages and household products. Many of these crops are nutritious, high value and stress tolerant. The paper concludes that African crops hold significant promise in improving the resiliency of global food production systems, to mitigate climate change and alleviate food insecurity and rural poverty, especially in dry regions of the world. It is hoped that this review contributes to teaching the next generation of agriculturalists, food scientists and international development professionals about the valuable contributions of Africa's resilient crops and peoples.

“…The two main cultivated okra, A. esculentus and A. caillei, are native of Asia and Africa, respectively (Adeoluwa & Kehinde 2011). The Asian species (A. esculentus) also referred to as common okra is now cultivated throughout the world and accounts for 95% of okra cultivated area globally; while the African okra (A. caillei) is primarily cultivated in Africa and accounts for 5% cultivated area (Ahiakpa et al 2017).…”

Multivariate Analysis of Genetic Diversity Among Okra (Abelmoschus spp.) Cultivars Grown in Côte d’Ivoire Based on Agro-morphological Traits

Crop improvement for sustainable agriculture requires information about the genetic variability of traits that helps identify suitable parents. This study was conducted to investigate the extent of genetic diversity among 12 okra cultivars grown and marketed in Côte d'Ivoire, using 12 quantitative and 11 qualitative agro-morphological traits. A Randomized Complete Block Design (RCBD) with five replications and two multivariate techniques, viz. principal component analysis (PCA) and cluster analysis (CA) were used. The okra cultivars evaluated showed wide variation in quantitative traits but minimal variation in qualitative traits except for leaf and fruit shapes. The first two PCs explained 70.489% variation and identify seven traits (day to flowering, stem diameter, plant height, number of fruit ridges, number of fruits per plant, fruit yield and number of seeds per fruit) that play a prominent role in the differentiation of the okra cultivars, and therefore could be used as good criteria for selection in okra improvement. PCA and CA grouped the total cultivars into three divergent clusters exhibiting specific characteristics: vigor and good yield for cluster I, short plants and earliness for cluster II and high yield for cluster III. The results of this investigation indicated that substantial variability was present in the okra studied. The cultivars of the divergent clusters constitute interesting okra genetic resources that can be used as a parental material for further breeding.
