Rubber tree breeding and the dissemination of planting material for plantations are closely linked to propagation methods. Since the progress made by switching from multiplication by seed to propagation by bud...

Genetic Determinism of Sensitivity to Corynespora cassiicola Exudates in Rubber Tree (Hevea brasiliensis)

An indirect phenotyping method was developed in order to estimate the susceptibility of rubber tree clonal varieties to Corynespora Leaf Fall (CLF) disease caused by the ascomycete Corynespora cassiicola. This method consists in quantifying the impact of fungal exudates on detached leaves by measuring the induced electrolyte leakage (EL%). The tested exudates were either crude culture filtrates...

Analysis of Genetic Diversity and SSR Allelic Variation in Rubber Tree (Hevea brasilensis)

Development of a genetic linkage map of rubber tree (Hevea braziliensis) based on microsatellite markers

Background Rubber tree (Hevea spp.) is the main natural rubber producing crop, and it is cultivated in numerous equatorial, tropical and subtropical areas. Hevea spp. is an outcrossing perennial species and belongs to the botanical family Euphorbiaceae. Breeding of rubber tree, like for many other tree crops, is a long term process. Large scale cultivation of a new cultivar can only be reached ...

Analysis of genetic diversity in early introduced clones of rubber tree (Hevea brasiliensis) using RAPD and microsatellite markers

Genetic analysis in 53 early introduced clones of rubber tree (Hevea brasiliensis) collected from different areas in Southern Thailand was performed using RAPD (Random Amplified Polymorphic DNA) and microsatellite markers. Seventeen cultivated clones (34 samples) were also included to compare DNA patterns. DNA was isolated from leaf samples using CTAB buffer. One hundred and ninety two 10-base ...
