Abstract:
Eighteen interspecific hybrids from eight different Cuphea species have been confirmed morphologically and cytologically. Seven hybrids from reciprocal crosses of various accessions of the herbaceous annual C. procumbens (N = 9) and the semiwoody perennial C. llavea (N = 9) exhibited a relatively high degree of fertility. Some hybrids have horticultural potential and are currently undergoing evaluation as new pot or bedding plants. Other hybrids that are sterile due to meiotic irregularities are: C. procumbens (N = 9) × C. crassiflora (N = 12); C. procumbens (N = 9) × C. leptopoda (N = 10); C. procumbens (N = 9) × C. leptopoda (N = 8); C. procumbens (N = 9) × C. lanceolata (N = 6); C. lanceolata (N = 6) × C. llavea (N = 9); C. lanceolata (N = 6) × C. lophostoma (N = 8); C. leptopoda (N = 10) × C. laminuligera (N = 10); C. procumbens (N = 9) × C. caesariata (N = 18); and C. lanceolata (N = 6) × C. caesariata (N = 18). C. leptopoda × C. laminuligera is of considerable interest, because it is the first successful interspecific hybrid between species in different fatty acid groups. A relatively fertile amphidiploid of C. leptopoda × C. laminuligera was induced by colchicine. Seed has been produced by self-pollination of the amphidiploid and attempts are being made to backcross the hybrid to the original parents.
