Abstract
Lilies have featured in our culture for centuries.
What makes these flowers particularly attractive to breeders is the immense richness of highly diverse species, which – owing to the dynamic progress in biotechnology – can be even more readily crossed.
By crossing various hybrids, we are able to produce an infinite number of floral forms.
Poland does not have a long tradition in breeding lilies.
The breeding work on lilies was started by Stanisława Dąbrowska in 1963, at the Plant Breeding and Acclimatization Institute in Puławy.
Since 1998, the Research Centre for Cultivar Testing (COBORU) has registered 14 Polish cultivars of lilies, which had been bred by Stanisława Dąbrowska, Anna Wilkońska and Kazimierz Mynett.
Lilies which belong to the group of Asiatic hybrids are easily hybridized, and have therefore drawn interest of many breeders.
Among the distinguishing features of these lilies there are early flowering modest requirements in terms of the substrate or climate and the highest (among all lilies) tolerance to diseases.
Moreover, when grown from seeds, these lilies quickly enter the flowering phase.
During the present study, the seedlings obtained from the hybridization of cultivars and clones of lilies which belong to the group of Asiatic hybrids, such as Abizag × Connecticut King (ACK 49 indiv.) and Altair × Miss Alice (AMA 26 indiv.), were verified, according to the COBORU methodology, with respect to their tolerance to the climatic conditions prevailing in the region of Warmia and Mazury.
During the vegetative season, measurements were taken of the following morphological traits (as recommended by the COBORU): beginning of the vegetative growth, beginning of flowering, end of flowering, height and length of the inflorescence, assessment of the shoots and foliage, measurements of single flowers, determination of the colour of flowers acc. to the colour chart RHSCC published in London.
Most of the ACK hybrids obtained in this experiment inherited the colour of the perigon and spots from the clone Abizag. In turn, 4 colours: yellow, orange, bright- and dark-red, could be distinguished among the AMA hybrids.
What makes these flowers particularly attractive to breeders is the immense richness of highly diverse species, which – owing to the dynamic progress in biotechnology – can be even more readily crossed.
