Abstract
Observations were carried out on 11 generations of red-flowering Delphinium University Hybrids to determine plant variation and to establish the rate of progress.
It proved that plant height varied considerably within each generation, but the average height did not change very much through the years (total average height 95 cm). Spike length improved remarkably, the average being round 60 cm in the past two years.
The average number of flowers per spike tripled and the average flower diameter went up from 4.5 to 5.7 cm, an increase of 27%. At present semi-doubleness is almost 100% and the colour range covers most basic colours, tints and shades in pink, red and carmine.
The average conformation improved significantly but since 80 – 90% of each progeny still has to be discarded for one or another shortcoming, the material has not yet reached the final stage of development.
