Evaluation of Anthurium variability (Anthurium andreanum) in the F1 population

Anthurium andreanum is one of the popular flowers in the floriculture industries and the biggest cluster in the Araceae group. Genetic variabilities of Anthurium andreanum were obtained through hybridization and conventional breeding program. The study’s objective was to evaluate the morphological character variation of anthurium in the F1 population. The F1 population of anthurium crossing was used for observation and evaluation in this research. The parameter observations were the morphological character of spadix and spathe, quantitative characters comprised of spathe width and length, spadix length, and the total number of flowers per plant in the first flowering stadia. There were 77 plants in the F1 population of crossing between anthurium cv. Sempre x Alvin. The longest spadix was 4.8 cm (SA.18), the longest spathe was 8 cm (SA.19), and the widest spathe was 8.7 cm (SA.19). Average of flowers per plant in the first blooming stadia was about 2-4 flowers. Variation of morphological characteristics was obtained in F1 population evaluation in some parameters. The evaluation showed that most offspring in the F1 population were dominantly inherited from A. Sempre.
