Pacureanu Joita Romanian Agricultural Research 2008

Other claims from this paper (6)

Observation Romanian areas differed in broomrape infestation and virulence groups.
Observation A new highly virulent broomrape population attacked sunflower in Romania in 2006.
Observation Many commercial sunflower hybrids lost resistance to the parasite near the Black Sea.
Method / resource Sunflower race differentials identified a new highly virulent broomrape population.
Observation Several sunflower germplasm genotypes fully resisted the new broomrape population.
Recommendation The resistant sunflower lines can be used for resistance genes and hybrid development.
