The NS-H-52 hybrid possesses genetic resistance to new aggressive races of downy mildew. At the same time, studies show that this genotype is highly susceptible to broomrape.
In scientific literature, the hybrid is mentioned in works studying autofertility, that is, the ability for self-pollination. This hybrid belongs to earlier developments and appears more often in comparative trials than in modern seed catalogs.
