| Abstract:
As part of a wider breeding programme, graft incompatibility in apricots using three cultivars and six rootstocks was studied. Rootstocks were propagated by taking softwood cuttings of the following six cultivars: the peach rootstocks ‘LESIBERIAN’ and ‘PS-1’, myrobalan ‘MY-KL-A’, the apricot rootstock ‘M-LE-1’ and two interspecific hybrids, ‘VVA-1’ Krymsk®1 (P. tomentosa × P. cerasifera) and ‘AP-1’ Krymsk®86 (P. persica × P. cerasifera). Three apricot varieties were then chosen for simultaneous tongue-grafting onto the softwood cuttings of the rootstocks. These were ‘Velkopavlovická’, a type of Hungarian Best which normally has good affinity for its rootstock, ‘Hélčne du Roussillon’ which typically has a bad affinity, as a control, and ‘Harcot’. | |
