Abstract:

The postproduction quality of 33 cultivars and 178 Pennsylvania State Univ. breeding lines of Pelargonium x domesticum L.H. Bailey was evaluated in a simulated consumer environment. Petal abscission was the primary factor that reduced post-production ratings (PPR). The heterozygosity of some cultivars was indicated by the range of PPR of progeny from self-pollinations. This range of PPR implies that P. x domesticum has genetic variation for postproduction quality that can be used in a breeding and selection program. Few progeny with high PPR were produced from either self- or cross-pollinations involving parents with low PPR. Many of the superior progeny resulted from parents with high PPR. Therefore, progeny with improved postproduction quality can be developed by selecting parents with high PPR.
