The project of breeding goals in 2023 for amaryllis, calla lily and caladium have completed including 50 amaryllis hybrid combinations, 40 calla lily cross combinations, and 50 caladium hybrid combinations . A total of 140 combinations have been crossed and sowing and embryo culture work. In addition, the cultivation of flowering bulbs planted in the field and the soilless medium in the greenhouse were also carried out. A total of 950 individual plants of amaryllis hybrid combination, 350 calla lily and 450 caladium were planted, for a total of 1,750 plants. In the amaryllis breeding section, potential progenies of H107002, H1071006 and H1071007 were screened based on the number of small scale bulbs reproduced, floret tropism, flower color type and other traits. Breeding in calla lily, Plant the individual plants with heat-tolerance potential selected using leaf cell membrane thermostability (CMT) detection technology in summer and observe the plant growth traits. As a result, the progeny with heat-resistant potential were screened as 94011, 94013-1 and 94030. In the caladium breeding section, from the evaluation of leaf shape, color, and leaf yellowing and withering time, three potential progenies which are CHB920443-09, CHB920464-18 and CHB950033-11 have been screened.
