Genetic diversity in Guazuma crinita from eleven provenances in the Peruvian Amazon revealed by ISSR markers
Popis výsledku v původním jazyce
Guazuma crinita is an important fast-growing timber tree species widely used in agroforestry systems in the Peruvian Amazon. The objectives of our research were (i) to assess genetic diversity of G. crinita using inter-simple sequence repeat (ISSR) markers and (ii) estimate correlation between genetic and geographic distances among provenances. The sample included 44 genotypes from 11 provenances in the Aguaytia and neighboring Pachitea watersheds in the Peruvian Amazon. Ten ISSR primers amplified a total of 65 bands of which 61 were polymorphic (93,8 %). The range of DNA amplification varied from 260 to 2,200 bp. Among the provenances, Macuya exhibited the highest percentage of polymorphic bands (PPB) with 67,7 %, 0,21 Nei gene diversity (He) and 0,33 Shannon index (I).Overall genetic differentiation (Gst) was 0,03, indicating 97 % of genetic diversity within provenances. Gene flow (Nm) was 12,9 alleles per generation.Cluster analysis was not related to geographic origin, suggesting a common gene po
