“…RAPD have been used for different number of species, independent of the strategy of reproduction, with success as in Coffea arabica autogamous (Diniz et al 2005); C. canephora allogamous (Ferrão et al 2009), Aspidosperma allogamous (Torezan et al 2005), Zea mays self-fertilized (Souza et al 2008), Catharantus roseus (Shaw et al 2009), Cassava allogamous (Ferreira et al 2008). Chiari et al (2007) highlighted the importance of knowing the genetic variability in the Brachiaria germplasm bank accesses for successful plant breeding plans, planning of divergent crosses and guidance of new collections or germplasm exchange.…”

“…Regarding RAPD markers, Rinaldi et al (2007) also did not infer a significant correlation between heterosis and productivity in Brazilian popcorn populations. Different studies have reported on the successful use of molecular markers in the evaluation of the genetic diversity in maize and its association with heterosis (Lanza et al, 1997;Sun et al, 2004;Souza et al, 2008). However, these studies did not use traits related to productivity.…”

ABSTRACT. Diallel analysis was used to obtain information on combining ability, heterosis, estimates of genetic distances by random amplified polymorphic DNA (RAPD) and on their correlations with heterosis, for the popcorn varieties RS 20, UNB2, CMS 43, CMS 42, Zélia, UEM J1, UEM M2, Beija-Flor, and Viçosa, which were crossed to obtain all possible combinations, without reciprocals. The genitors and the 36 F 1 hybrids were evaluated in field trials in Maringá during two growing seasons in a randomized complete block design with three replications. Based on the results, strategies for further studies were developed, including the construction of composites by joining varieties with high general combining ability for grain yield (UNB2 and CMS 42) with those with high general combining ability for popping expansion (Zélia, RS 20 and UEM M2). Based on the RAPD markers, UEM J1 and Zélia were the most genetically distant and RS 20 and UNB2 were the most similar. The low correlation between heterosis and genetic distances may be explained by the random dispersion of the RAPD markers, which were insufficient for the exploitation of the popcorn genome. We concluded that an association between genetic dissimilarity and heterosis based only on genetic distance is not expected without considering the effect of dominant loci.

“…Many factors could influence genetic distance values, such as the number of markers used and distribution of the markers in the genome (Munsch, 2008). In total, 21 markers were used in the study, and according to Souza et al (2008) 16 markers are enough for genotype analysis. Munsch (2008) analyzed 30 genotypes using 20 SSR markers and revealed 71 alleles, which is much less than the number of alleles obtained in this research.…”

Plus-hybrid effect refers to a combined effect of cytoplasmic male sterility (CMS) and xenia in maize (Zea mays L.) It could be used in commercial production by growing a mixture of 80% CMS hybrid and 20% of another fertile hybrid. The aim of this research was to examine individual and combined CMS and xenia effects on two hybrids widely grown in Serbia. Sterile and fertile versions of ZP 1 and ZP 2 hybrids (three-way; Iodent × Lancaster dents) were used as females, while ZP 1, ZP 2, ZP 3, ZP 4, and ZP 5 (three-way or single cross; Iodent (BSSS) × Lancaster dents) were used as pollinators. All of them belong to medium maturity group. The trial was set up at one location in Serbia (Zemun Polje) in 2009, 2010, and 2011. Molecular analysis of the five genotypes was done using simple sequence repeat (SSR) primers. Plus-hybrid effect on grain yield ranged from -6.2% to 6.2%; on thousand kernel weight from -1.7% to 5.2%; on number of kernels per area from -1.0% to 8.0%. The poor response could be due to a use of three-way instead of single cross hybrids in S type of sterility. Modified Rogers' distance between hybrids was in the range 0.211 to 0.378 and was not relevant for the effect, which depended mostly on the sterile hybrid genotype and the fertile hybrid pollinator ability. This approach should be more suitable for female hybrids with slightly poorer performance, already being produced on a sterile base.
