Title

Ad hoc breeding and occasional disorders – a case study on current season needle necrosis in Nordmann fir (Abies nordmanniana (Steven) Spach)

Other claims from this paper (5)

Observation A proportion of clonal parents had moderately or severely affected offspring.
Association The two parent rankings overlapped moderately.
Observation Reference trees gave a low heritability estimate for needle necrosis.
Method / resource Ad hoc breeding and parentage analysis identified high-risk parents.
Recommendation The authors conclude ad hoc breeding can manage unpredictable disorders.
