“…PUMs were generated by 4 primers which distinguish genotypes G6, G8, G14, and G16 while, NUMs successfully identified genotypes G3, G4, G5, and G12. The present study results had a higher number of fragments (Figure 1 and Table 2) than that recorded by Sharawy et al (2011) and Vivodík et al (2015) on some teosi nte and maize studies and agreed with the results of Ristic et al (2013) who analyzed 21 genotypes with 7 primers and obtained an average of 10.8 bands per primer. Also, the present findings are in partial agreement with that of Bauer et al (2005) who detected 78.2 % polymorphic markers amongst 11 early maturing maize hybrids using 10 RAPD primers.…”

“…Also, the present findings are in partial agreement with that of Bauer et al (2005) who detected 78.2 % polymorphic markers amongst 11 early maturing maize hybrids using 10 RAPD primers. On the other hand, Bruel et al (2006) and Sharawy et al (2011) obtained a higher level of polymorphism (84.44 and 99% respectively) studying maize inbred lines using RAPD markers. The difference in the level of polymorphism obtained is mainly attributed to the degree of divergence between the different genotypes studied.…”

“…These findings are in agreement with that of Bruel et al (2006) and Souza, et al, (2008) who constructed a dendrogram with five groups for selected maize lines based on the RAPD marker. Thus, the genetic relationships revealed by RAPD marker can be used to establish a consistent heterotic pattern between characterizing different maize lines (Carvalho et al, 2004;Rinaldi et al, 2007;Sharawy et al, 2011;Balážová, et al, 2016 andVivodík, et al, 2017) Fig. 3 Dendrogram constructed according to Nei and Li's coefficient using Unweighed Pair-group Arithmetic Average (UPGMA) and similarity matrix of the RAPD generated data for the 16 Zea mexicana genotypes.…”

Maize-Teosinte hybrids are of significant interest to maize breeders as a resource of genetic diversity during the maize domestication process as a genetic pool for maize improvement. This study examines the genetic diversity and population structure of 16 Zea mexicana populations which are currently active in Zea breeding programs in Egypt using Random Amplified Polymorphic DNA (RAPD) and Amplified Fragment Length Polymorphism (AFLP) markers. RAPD analysis (14 primers) produced 141 bands; out of which, 102 (72.3%) were polymorphic. On the other hand, AFLP (5 primer combinations) yielded 276 peaks including 267 (96.7%) polymorphic ones with an average of 53.4 peaks per primer combination. A total of 11 unique RAPD markers were created by 6 primers and identified 8 genotypes. The five primer combinations generated 56 unique amplicons that successfully distinguished 12 out of the 16 genotypes tested. Furthermore, the number of observed alleles (Na), effective multiplex ratio (EMR), and polymorphic information content (PIC) indices showed higher values for AFLP (2.00, 53.4, and 0.21) than for RAPD (1.67, 7.3, and 0.15). Cluster analysis based on Nei and Li genetic distance and an Unweighted Pair Group Method with Arithmetic Mean (UPGMA) revealed 5 main clusters representing the 16 Zea mexicana confirming the population structure analysis obtained. High variability of the studied teosinte genotypes using RAPD and AFLP markers will provide valuable tools for Zea mexicana breeding programs in Egypt.

Maize (Zea mays L.) is the third most important cereal crop in the world because of its nutritional value and industrial benefits. Molecular markers are used mainly by the breeders to study the genetic variability of genotypes and its application in the breeding process. Two types of molecular markers, 10 RAPD primers and 10 SCoT primers, were assayed to determine the genetic diversity of 25 Slovak maize lines and 25 maize varieties. A high level of polymorphism was found with both RAPD and SCoT markers, which was confirmed by high average PIC values using both techniques. The efficiency of individual marker techniques in the detection of genotype diversity can be compared by calculating the marker index (MI) and detecting diversity index (DDI). A higher MI (11.788) and DDI (2.358) value was achieved by the SCoT technique compared to the RAPD method. Three joint dendrograms and PCoA plots constructed based on RAPD, SCoT and both methods combined confirmed the unambiguous separation of maize lines and varieties from each other. The results obtained from the RAPD and SCoT analysis can be used for the selection of potentially suitable biological sources for further marker-assisted breeding.
