Segregation at microsatellite loci in haploid and diploid gametes of Musa
TL;DR: Analysis of the paternal diploid banana accession and its selfed progeny suggests that this accession is highly heterozygous, and data indicate that microsatellite markers are well suited for marker-assisted selection systems in Musa.

Ploidy determination in Musa germplasm using pollen and chloroplast characteristics
TL;DR: Although pollen diameter and chloroplast number increased with ploidy, the use of the sporophytic parameter appears to provide a more satisfactory means of estimating ploidsy status in Musa.
Comparison of DNA marker and pedigree-based methods of genetic analysis in plantain and banana (Musa spp.) clones. II. Predicting hybrid performance
TL;DR: Pedigree and DNA marker-based methods were used to predict the performance of triploid progeny from tetraploid-diploid crosses, based on parental heterozygosity, genetic relatedness, and expected contribution to their progeny.

TL;DR: This study was conducted to compare different PCR-based marker systems (RAPD, VNTR and AFLP) for the analysis of breeding populations generated from two diverse Musa breeding schemes and detected a high level of polymorphism between parental genotypes and within progeny populations.
VNTR-based diversity analysis of 2x and 4x full-sib Musa hybrids
TL;DR: There was a significant association between the genetic similarity (based on VNTR) and the phenotypic resemblance (r = -0.546, P = 0.042) and this type of molecular marker analysis can not be used for inferring hybrid ploidy.
