Several cultivars that have been categorized as resistant did not show complete resistance (immunity) to BS (Sreedharan and Menon 1974).
They found that none showed complete resistance and classified the cultivars as relatively resistant, moderate, or susceptible (Goto and Watanabe 1975).
If you're met with complete resistance, you need to make some tough decisions about how risk-disposed you are.
In some persons, tissue receptors for androgens are absent or reduced, forming a spectrum of syndromes of partial to complete resistance to androgens.
Besides partial resistance, breeders mostly use complete resistance driven by R genes.
Moreover we show that complete resistance triggered by major resistance genes could also be affected.
Any potato cultivar with complete resistance to this disease is not recognized, so far.
The major QTL (QTL11) that controls complete resistance was mapped on chromosome 11 by the SSR markers RM144 and RM224.
However, C. parapsilosis CDF0013 showed complete resistance towards both the aerial and root extracts of the plant (Table 3).
However, despite extensive efforts, no single genes or QTLs for complete resistance to BS, BSR or BGR have been discovered.
