Description

The branched broomrape, Phelipanche ramosa (L.) Pomel, is a parasitic weed that can infest several crops, notably tobacco, hemp and tomato. In western France, it has recently adapted to a new host, oilseed rape. We collected P. ramosa samples from fields cultivated with six different crops across Europe. Data from SSR markers and DNA sequences showed strong host-associated genetic differentiation.

File SSRdata-Pramosa1611.txt contains sampling locations, host crops and microsatellite genotypes.
