| Abstract:
The studies on the germination of seeds obtained from 85 cross-combinations between different parental forms of apple, performed in the orchard in the spring of 2004-2006, were conducted from 2005 through 2007 at the Research Institute of Pomology and Floriculture in Skierniewice. The seeds from the crossing programmes were treated with the fungicide Benlate (0.1% solution) by soaking for 24 hours before stratification. Stratification involved placing the seeds individually in the cells of plastic multipots. Then the containers with the seeds were placed in cold storage at a temperature of +2°C for a period of 30 days to undergo the stratification process. After this time, the containers were transferred to a greenhouse, and the ability of the seeds to germinate was evaluated. After stratification, the greatest number of seeds germinated in three cross-combinations made in 2005 – ‘Free Redstar’ x ‘Retina’ (89%), ‘Free Redstar’ x ‘Sampion’ (87%), and ‘Free Redstar’ x ‘Pinova’ (85%), and the least in three combinations of crossings made in 2006 – ‘Ariwa’ x J-79 (18%), ‘Ligolina’ x ‘Ligolina’ (17%), and ‘Ligolina’ x ‘Sampion’ (13%). | |
