“…Mango cultivars grouped in the rest of clusters had mean values of the characters within the ranges of minimum and maximum overall mean values of cultivars and had similarity for two or more qualitative traits. Grouping of crop genotypes in different clusters is helpful to identify parental lines for breeding or further development of varieties through selection (Karanjalker and Begane, 2016;Majumder et al, 2013). Hence, the resulted cultivar clusters with distinguished characters can be used in mango improvement programs of the country.…”

Little efforts have been made on mango genetic resource assessment in Ethiopia though it is one of the major fruit crops. This study was conducted to assess the diversity of 69 mango cultivars of different growing regions of the country based on 44 phenotypic descriptors. The results of both univariate and multivariate analysis of variance computed for quantitative data, and results from descriptive statistics for qualitative characters indicated the presence of phenotypic variation among the cultivars. Further analysis of Principal Component Analysis (PCA) indicated the first four components explained more than 75% of the total variation in which most fruit, seed and leaf characters contributed much to the observed variation. The cultivars were grouped into 13 clusters by Unweighted Pair Group Method with Arithmetic Means clustering method from the Euclidean distances estimated from phenotypic characters. The three clusters (II, X, and XIII) constructed each by one cultivar while others encompass more than one irrespective of their geographic regions. This indicated the presence of diversity among cultivars in Ethiopia which can be exploited for further improvement, use, and conservation of mango genetic resources.

“…Concerted research efforts have been made to address this pitfall. Advancements in recent years include marker-assisted selection for genes of interest (Karanjalker and Begane, 2016), the development of speed breeding methodologies to shorten generation time (Mehrabi et al, 2018), targeted breeding using directed approaches (as opposed to trial-by-error breeding strategies), reverse-breeding strategies to introduce genetic diversity (ancestral traits) back into commercial crops (Palmgren et al, 2015), and random chemical mutagenesis (Jankowicz-Cieslak et al, 2017). These progressive breeding programs have made strides in increasing crop quality and quantity, but it is increasingly recognized that they do not target all possible sources of phenotypic variability (Rodríguez López and Wilkinson, 2015).…”
