Genetic variability and heterozygosity of cocoa accessions of Parinari (Pa) population, based on microsatellite markers
The objective of this work was to study the genetic variability and the heterozygosity of accessions of the Parinari (Pa) series in the collection of the Active Germplasm Bank (BAG) of the Cocoa Research Center (CEPEC), CEPLAC, Bahia using microsatellite markers. In the present study, 34 accessions of Theobroma cacao L. were used, being 25 of the Parinari series. Twelve microsatellite loci were analyzed generating a total of 49 alleles. Results indicated genetic variability among the Parinari accessions with genetic distances varying from 0.00 to 0.64 and heterozygosity levels between 11 and 72%. About 40% of the accessions presented heterozygosity equal or greater than 50%.
期刊介绍：
The CBAB – CROP BREEDING AND APPLIED BIOTECHNOLOGY (ISSN 1984-7033) – is the official quarterly journal of the Brazilian Society of Plant Breeding, abbreviated CROP BREED APPL BIOTECHNOL.
It publishes original scientific articles, which contribute to the scientific and technological development of plant breeding and agriculture. Articles should be to do with basic and applied research on improvement of perennial and annual plants, within the fields of genetics, conservation of germplasm, biotechnology, genomics, cytogenetics, experimental statistics, seeds, food quality, biotic and abiotic stress, and correlated areas. The article must be unpublished. Simultaneous submitting to another periodical is ruled out. Authors are held solely responsible for the opinions and ideas expressed, which do not necessarily reflect the view of the Editorial board. However, the Editorial board reserves the right to suggest or ask for any modifications required. The journal adopts the Ithenticate software for identification of plagiarism.
