Abstract:

The inheritance of fifteen important traits of Anthurium andraeanum Linden was investigated among the F1 progenies of three crosses between pot- and cut-cultivars, ‘Pink champion’ X ‘Acropolis’, ‘Purple Princess’ X ‘Cheers’, ‘Sierra’ X ‘Tropical’, respectively. Statistical analysis showed that the mid-parent value of average plant height, spathe length, spathe width, left ear distance, right ear distance, spadix length, spadix diameter, pedicel length, pedicel diameter, petiole length, petiole diameter, leaf length, leaf width in F1 generation was 139.35%, 99.65%, 107.05%, 85.84%, 97.55%, 103.31%, 104.15%, 106.28%, 107.63%, 116.36%, 110.36%, 142.46%, 109.76%, 117.90% and 128.10%, respectively, and a large number of transgressive individuals appeared. The hybrids showed obvious inheritance tendency of cut anthurium cultivars. The heterosis was obvious, even the levels were slightly different among crosses. The 15 quantitative characters were clustered into 4 classes: 1) spathe, 2) spadix, 3)pedicel and petiole, and 4) leaf. The correlation analysis showed that the traits in same class were correlated very significantly, while the traits among different groups was weak or irrelevant. In all, the morphological characters of F1 progenies were separated extensively and showed an abundant genetic diversity, which would facilitate directive breeding in anthurium with high efficiency.
