“…Cluster I (56%) comprising 14 accessions was the biggest and showed high homogeneity among them or the least genetic variation, followed by clusters IV, III, V, II, and VI consisting of 4, 3, 2, 1, and 1 accessions, respectively (Table 4). The clustering of the accessions indicated no parallelism between genetic diversity and geographical diversity (Sigrist et al 2011). In line with this, Verma et al (2014) clustered 83 turmeric genotypes into 10 clusters using Mahalanobis distance.…”

Turmeric, a vegetatively propagated crop, may have restricted variability from which to breed new cultivars. Understanding the genetic variability of a species is crucial for the progress of a genetic breeding program and requires characterization and evaluation of accessions. The objectives of this study were to determine extent of variability, relationships between different agro-morphological traits, and diversity among 25 different accessions of turmeric. The present experiment was conducted at the Vegetable Research Farm, Department of Horticulture, Sam Higginbottom Institute of Agriculture, Technology and Sciences, Allahabad, India during 2008-2009 and 2009-2010. Accessions were arranged in a randomized complete block design with three replications. Significant mean square of accessions for all the traits studied indicates the existence of sufficient genetic variability among the studied accessions. The rhizome yield exhibited highly significant and positive association with plant height, number of leaves plant −1 , number of tillers plant −1 , weight of rhizomes plant −1 , length of primary rhizome, and dry matter recovery. The highest positive direct effect on rhizome yield was exerted by plant height. Multivariate analysis techniques allowed an effective study of genetic divergence and the grouping of the 25 accessions into six clusters. The highest inter-cluster distance was observed between cluster II and IV, accessions from these clusters can be used as potential parents for future breeding programs.Key words: agro-morphological descriptors, character association, direct/indirect effect, genetic diversity, Curcuma longa L.Résumé : Le curcuma est une plante qui se multiplie de façon végétative, aussi sa variabilité pourrait-elle être restreinte, ce qui nuirait à la création de nouveaux cultivars. Il est capital de bien comprendre la variabilité génétique d'une espèce si on veut mieux l'hybrider, ce qui signifie qu'il faut en caractériser et évaluer les obtentions. La présente étude devait établir l'importance de la variabilité, les liens entre divers caractères agro-morphologiques et la diversité de 25 obtentions de curcuma. L'expérience a été réalisée à la ferme expérimentale de cultures maraîchères du département d'horticulture de l'Institut Sam Higginbottom d'agriculture, de technologie et de science à Allahabad (Inde), en 2008-2009 et 2009-2010. Les obtentions ont été réparties en blocs aléatoires complets et les essais ont été répétés trois fois. Une variance significative pour tous les caractères examinés indique que les obtentions varient toutes assez sur le plan génétique. Le rendement en rhizomes présente une association positive significative avec la taille du plant, le nombre de feuilles par plant, le nombre de talles par plant, le poids des rhizomes par plant, la longueur du rhizome principal et la quantité de matière sèche récupérée. C'est la taille du plant qui exerce directement le plus fort effet positif sur le rendement en rhizomes. Les techniques d'analyse à variables multi...

“…There have been several works on the genetic diversity of mangos that particularly used molecular markers [17][18][19]. The evaluation of genetic diversity through morphological characteristics has also been widely employed in studies [8,20]. This methodology is quite efficient, as demonstrated by Ramessur et al, [16] who evaluated mango tree diversity through RAPD markers and morphological traits.…”

Mangifera indica (mango) is a typically tropical fruit with considerable economic value. Brazil features a wide variety of cultivars of this fruit, most of which are known under several different names. Indeed, the nomenclature of mango varieties is still quite confusing. Up to now there has been no well-defined scientific principle to differentiate them. The objective of the present work is to compare the different clustering methods in assessing genetic divergence among mango accessions, as well as identify the minimum efficient descriptors for that crop. A total of 20 mango accessions in Cáceres, Mato Grosso state, Brazil were evaluated. When building dissimilarity matrices, the descriptors were divided according to the following groups: leaf, flower/inflorescence, fruit, seed and growth habit/ripening period. With these divisions, combinations were performed among the groups of descriptors. The similarity index was used to obtain the dissimilarity matrices. Later, the accessions were clustered using the methods of Tocher, Ward and UPGMA. The study observed that it was possible to reduce the number of descriptors from 64 to 35, and that the clustering methods were compatible with the study of the genetic diversity of mango.

“…Clustering analysis has been used to facilitate the visual interpretation of genetic diversity in plants. The use of these techniques has been extensively reported in scientific studies on several crop species such as cassava (Nick et al, 2008;Campos et al, 2010), capsicum (Sudré et al, 2006;Bento et al, 2007;Aklilu et al, 2016), commom bean (Chiorato et al, 2005;Legesse et al, 2013), sugarcane (Sanghera et al, 2015), maize (Teodoro et al, 2015), onion (Buzar et al, 2007;Singh et al, 2013), açai palm , Brazilian turmeric (Sigrist et al, 2011), and garlic (Menezes Sobrinho et al, 1999;García Lampasona et al, 2003;Mota et al, 2006;Panthee et al, 2006;Zahedi et al, 2007;Viana et al, 2016), among others.…”
