Popis:	This study explored different character data sets (random amplified polymorphic DNA (RAPD) and morpho‐nut characters), techniques, and systematic methodologies in an attempt to reconstruct the phylogenetic relationships and origins of New Zealand chestnut (Castanea spp.) selections. The study was prompted by confusion regarding the relationships of New Zealand chestnut selections and the introduced chestnut species in New Zealand. RAPDs demonstrated that C. dentata is not one of the parents of the chestnut selections and revealed that ‘1002’ and ‘1007’ could be a hybrid of C. mollissima and C. crenata species. A comparison of the trees from RAPD and morpho‐nut characters showed that the trees were significantly congruent. The groupings of the chestnut species and the New Zealand chestnut selections were based on their geographic locations. The study also demonstrated that most of the New Zealand chestnut selections were not hybrids of C. sativa and C. crenata but rather most of the South Island s...
