| Abstract:
Diallel crosses were carried out between Asiatic lily cultivars, varying in flower longevity. The progenies were analysed for individual flower and total flower longevity and promising plants were selected for further testing. On clonal basis, the parent cultivars and 73 selected F1-plants were investigated. Among the different observed characters, were flower longevity, number of flowers per stem, flower opening speed and water uptake most relevant. The flower longevity measured at single plant basis appeared to be comparable to that on clonal basis. The number of flowers, water uptake and earliness seems moderately correlated to the individual flower longevity, while other characters such as number of leaves, stem weight and plant height showed no correlation. Water uptake of stems during post-harvest showed negative correlation with individual flower longevity. | |
