J. J. Xu, Zhao, B., Shen, H. F., Huang, W. M., Yuan, L. X., Xu, J. J., Zhao, B., Shen, H. F., Huang, W. M., and Yuan, L. X., Assessment of genetic relationship among Rhododendron cultivars using amplified fragment length polymorphism and inter-simple sequence repeat markers, vol. 15, p. -, 2016.

Genetic relationships of 17 Rhododendron cultivars, China, were assessed using inter-simple sequence repeat (ISSR) and amplified fragment length polymorphism (AFLP) markers. A total of 133 bands were obtained using nine selected ISSR primers, 129 (96.99%) of which were polymorphic; 267 bands were amplified by four AFLP primer pairs, 251 (94.01%) of which exhibited polymorphism. Based on these polymorphic products, a cluster analysis revealed similarities between the results of the ISSR and AFLP.

Genetic divergence of sugarcane varieties collected in the region of Lavras, Minas Gerais, Brazil

Genetic diversity among local accessions and varieties subsidize plant breeding programs, allowing the utilization of existing variability in plants that have already adapted to local climate conditions. An alternative to studying genetic variability is the study of diversity. The aim of this research was to study genetic diversity among sugarcane accessions and varieties used for the production of craft-distilled cachaça (distilled sugarcane alcohol) in the region of Lavras, Minas Gerais, Brazil.
