摘要

利用微卫星标记对巴伊亚州可可研究中心(CEPEC)活性种质资源库(BAG)中Parinari (Pa)系列种质的遗传变异和杂合性进行了研究。在本研究中，使用了34份可可树材料，其中25份为Parinari系列。分析了12个微卫星位点，共产生49个等位基因。结果表明，各品种遗传距离在0.00 ~ 0.64之间，杂合度在11% ~ 72%之间。约40%的材料杂合度大于或等于50%。

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 The article must be unpublished.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.
