“…However, this is an inferential criterion and it may not be so effective in quantifying or differentiating among populations. These results are in general agreement with the findings of Rao (1974) [11] , George et al (2005) [3] , Le et al (1998), Liu ShiBiao (2000) [7] , Samal et al (2002) [12] , Liu and Chen (2002) [6] and Mariguele and Silva (2010b) [9] .…”

“…Cluster analysis for qualitative traits showed that all genotypes were grouped into 8 clusters using non-hierarchical Euclidean cluster analysis (Table -2). For qualitative parameter, maximum number of genotypes were grouped into cluster VIII (14) followed by cluster III (12). The minimum number of genotypes was found in cluster V (3) followed by cluster I(4).…”

C.G.) duringKharif 2013-14. The experiment was laid out in Randomized Block Complete Design with four replication, in-situ sixty genotypes of about 10 year age were selected for investigation, which were found as wild seedling plants on forest land and rice bunds in Kanker District-(C.G.). The treatments comprised of sixty genotypes for with different qualitative character viz total soluble solid, total sugar, reducing sugar, non-reducing sugar, titration acetic acid, keeping days, pulp ratio, pulp seed ratio, peel percentage and fruit yield per plant. The D 2 analysis classifies the genotypes into relatively homogeneous groups in such a way that within cluster diversity is minimized and between clusters diversity is maximized. The respective genotypes from diverse clusters can be utilized in breeding programme. Cluster analysis for qualitative traits showed that all genotypes were grouped into 8 clusters using nonhierarchical Euclidean cluster analysis (Table 4.15 and Fig. 4.5). For qualitative parameter, maximum number of genotypes were grouped into cluster VIII (14) followed by cluster III (12). Intra and Inter-Cluster distances among 8 clusters for qualitative traits in custard apple are presented in Table 4.16. The highest intra-cluster distance was recorded for cluster VI (48.65) followed by cluster II (46.79) and the smallest intra cluster distance was recorded in cluster III (0.00) followed by cluster V (8.15) for qualitative traits. Custard apple is a predominantly cross-pollinated (protogyny) crop and no information is available suggesting a change in its breeding behavior under varied environmental conditions. Discrimination of desirable parents for a successful hybridization programme is a difficult task for a plant breeder. Generally, geographical diversity has been considered as a measure of genetic diversity. However, this is an inferential criterion and it may not be so effective in quantifying or differentiating among populations.

“…Some used morphological markers (see references in Andrade et al 2019;Bionoset 2019), but genotyping with molecular markers such as isozymes, RAPDs, ISSRs, AFLP, microsatellites and ITS sequence data is now more usual, sometimes in combination with morphological descriptors; these studies have been carried out predominantly on material from India (e.g. Dhanaraj et al 2002;Rout et al 2002;Samal et al 2002;Archak et al 2003a, b;Samal et al 2003;Desai 2008;Archak et al 2009;Thimmappaiah et al 2009;Dashmohapatra et al 2014;Sethi 2015;Jena et al 2016), Brazil (e.g. Barros 1991;Cavalcanti and Wilkinson 2007;Pessoni 2007;Amaral et al 2017;Borges et al 2018), Nigeria (e.g.…”

Genetic diversity in wild populations of the restinga ecotype of the cashew (Anacardium occidentale) in coastal Piauí, Brazil

et al. 2019

The cashew, Anacardium occidentale, is a globally important tropical fruit tree, but little is known about its natural infraspecific systematics. Wild Brazilian populations occur in the cerrado biome and coastal restinga vegetation. We investigated whether wild coastal and domesticated populations could be distinguished genetically using inter-simple repeat molecular markers (ISSRs). In total, 94 polymorphic loci from five primers were used to characterise genetic diversity, structure and differentiation in four wild restinga populations and four domesticated ones from eight localities in Piauí state (30 individuals per population). Genetic diversity was greater overall in wild (%P: 57.2%, I: 0.24, H e : 0.15) than domesticated populations (%P: 49.5%, I: 0.19, H e : 0.12). Significant structure was observed among the eight populations (between-population variance 22%, Φ PT = 0.217, P ≥ 0.001), but only weak distinctions between wild and domesticated groups. Cluster and principal coordinate analyses showed marked genetic disparity in populations. No correlation of genetic and geographical interpopulation distance was found (Mantel test, r = 0.02032, P = 0.4436). Bayesian analysis found an eight-group optimal model (ΔK = 50.2, K = 8), which mostly corresponded to sampled populations. Wild populations show strong genetic heterogeneity within a small geographical area despite probable gene flow between them. Within-population genetic diversity of wild plants varied considerably and was lower where extractive activities by local people are most intense (Labino population). The study underlines the importance of wild populations as in situ genetic reserves and the urgent need for further studies to support their conservation.

“…Differences in the average similarity coefficients between selections and hybrids was very low, indicating hybridization. Samal et al (2003Samal et al ( , 2004 noted the genetic relationships of 25 varieties of cashew, collected from India on the basis of phenotypic characters and RAPD markers. They found 80 distinct DNA fragments with a range of 0.2-3.0 kb by using 11 selected random decamer primers.…”
