Abstract

The prostrate plant habit may be an important new trait for the garden chrysanthemum [Dendranthema x grandiflora Tzvelv. (=Chrysanthemum x morifolium Ramatuelle)] market. Fifteen prostrate and non-prostrate genotypes were evaluated in production trials, using Regular and Fast Cropping systems. At flowering, the following traits were evaluated: days to flowering (first, 50%, 100%), flowering duration, pot coverage, plant uniformity, and salability. Salability was measured with consumer evaluations. Genotypes differed significantly for days to first and 100% flowering, flowering duration, plant height, plant width, and plant uniformity. Cropping systems were significantly different for days to first and 100% flowering. 'Snowscape', a semi-prostrate day-neutral cultivar, was earlier than all other genotypes for days to first flower. It also had the longest flowering duration. 'Snowscape' would be the best genetic source for creating early, continual flowering cultivars. Most prostrate genotypes were as early as commercial cultivars. Genotype 90-275-27 was significantly shorter (prostrate) than all other genotypes and would be the best genetic source for prostrate plants. Genotypes 95-169-8, 92-237-9, 95-157-6, 95-169-10, 90-275-27, and 'Snowscape' had the most acceptable plant width for shipping. Plant uniformity of 95-169-10 and 95-169-8 matched that of 'Debonair' and 'Spotlight', all of which were significantly more uniform than the other genotypes. The least uniform prostrate was 95-331-10. 'Snowscape' had the highest (best) index of traits ranking and was significantly better than all other genotypes. Consumer evaluations were highest for non-prostrate cultivars.
