Popis:	Most coniferous species exhibit severe inbreeding depression. Selfed individuals usually have decreased viability, reduced vigour and morphological defects. The number of filled seeds after selfing Pinus radiata plus tree 850.55 was 48% that of the outcrossing, and 26.1% of the selfed seedlings died at an early stage. The segregation of 172 markers (covering 56% of the genome) in selfed progenies of radiata pine plus tree 850.55 was studied. Based on the segregation ratio of the markers, genes associated with inbreeding depression on viability were identified (P
