Assessment of the legitimacy of cocoa tree hybrids (Theobroma cacao L.) resulting from simple crosses using single nucleotide polymorphism (SNP) markers in Côte d’Ivoire
The legitimacy of 13 hybrid families resulting from crosses via manual pollination techniques was studied using single nucleotide polymorphism (SNP) markers. The aim of this study was to ensure the conformity of offspring resulting from simple crosses. Fifty-one individuals (39 descendants and 12 parent clones) were analysed using 84 SNP markers. The results revealed nonsignificant genetic differentiation between parents and progenies (P = 0.323). High allelic richness was also revealed, with the average number of alleles per locus ranging from 1.57 to 1.92, with an average of 1.77 in offspring and 2 in parents. Thus, 1% of the total variance was attributed to interpopulation variance, and 99% was attributed to intrapopulation variance. Low genetic differentiation (FST < 0.05) and genetic distances (0.03 < D < 0.09) were observed between hybrid families F2, F8, F10, F11, F12, F13 and F14 and their respective parents. These results confirm the legitimacy of the hybrids produced and suggest that the manual pollination work carried out at CNRA sites is reliable for faithfully reproducing hybrid material using known parents.
期刊介绍：
Genetic Resources and Crop Evolution is devoted to all aspects of plant genetic resources research. It publishes original articles in the fields of taxonomical, morphological, physiological, biochemical, genetical, cytological or ethnobotanical research of genetic resources and includes contributions to gene-bank management in a broad sense, that means to collecting, maintenance, evaluation, storage and documentation.
Areas of particular interest include:
-crop evolution
-domestication
-crop-weed relationships
-related wild species
-history of cultivated plants including palaeoethnobotany.
Genetic Resources and Crop Evolution also publishes short communications, e.g. newly described crop taxa, nomenclatural notes, reports of collecting missions, evaluation results of gene-bank material etc. as well as book reviews of important publications in the field of genetic resources.
Every volume will contain some review articles on actual problems. The journal is the internationalized continuation of the German periodical Die Kulturpflanze, published formerly by the Institute of Plant Genetics and Crop Plant Research at Gatersleben, Germany.
All contributions are in the English language and are subject to peer reviewing.
