Diversity analysis and evaluation of wild Abelmoschus species for agro-morphological traits and major biotic stresses under the north western agro-climatic condition of India

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

“…The three local cultivars of A. caillei were later than all the cultivars of A. esculentus. This result is supported by Gangopadhyay et al (2017) and Ogwu et al (2018) who reported similar behavior of cultivars of A. caillei compared to A. esculentus. Based on the result of the present study, selection for earliness can be made using the earliest maturing cultivars of A. esculentus which are Kousko, Cali and Emerald.…”

“…Regarding mean seed numbers per fruit in this study, all the cultivars of A. esculentus had higher mean values than those of A. caillei. This result is supported by Gangopadhyay et al (2017). However, the values of 100 seed weight were important in cultivars of A. caillei, especially in Local#2 and Local#3, probably because of the larger seeds of these cultivars.…”

“…The fact that the cultivars of A. caillei were grouped in the same cluster (cluster-I) reveals their close relationship. Gangopadhyay et al (2017) reported similar grouping of accessions of A. caillei in one cluster, indicating higher degree of morphological similarity among them. The clear distinction between the A. caillei cultivars and A. esculentus cultivars highlights the different genetic background of these two species and the independent identity of each of them.…”

“…Only Clemson seemed to straddle both cluster II and III when considering the two pattern of clustering, suggesting that this cultivar shared the characteristics of these two clusters. Clustering is a technique that can conveniently show the pattern of genetic relationships or proximity among the cultivars studied such that each group is homogeneous with respect to certain characteristics and each group should be different from other groups with respect to the same characteristics (Gangopadhyay et al 2017). Thus, the late maturing and tall cultivars of A. caillei were grouped into cluster I.…”

“…This fact would result in progenies with a broad genetic base and a higher probability of obtaining new genetic combinations with useful characteristics in segregating generations (Teodoro et al 2019). In addition to the genetic distance, the selection of the parents should also consider the special advantage of each cluster and each genotype within a cluster depending on the objective of hybridization (Gangopadhyay et al 2017). Each of the three clusters of this study exhibited a main specific interesting trait: vigor and good yield for cluster I, short plants and earliness for cluster II and high yield for cluster III.…”
