| Abstract: | In recent years, Bauhinia variegate, as an ornamental flower of native trees, has been widely used in the construction of gardens because of its excellent flowering performance, and has broad development prospects. The study focused on the field survey of about 1 000 plants in 11 landscape nodes of Guangzhou, and 60 excellent plants were selected as the base materials by using AHP (analytic hierarchy process). The plant shape, growth potential, crown density, flowering stage, flower color, quality in full-bloom stage, flower shape and flower diameter were evaluated. The results of cluster analysis showed that the first and the second class plants in the forest were as follows: LJC05, LJC01, HLS08, HLS09, HLS05, HLS03, YST01, YST03, HN04, CL01, LKY01, LJC06, LHH06, LHH08, LJC03, LJC02, HLS07, YST02, HLS04, LJC04, LHH07, LHH03, LHH02, LHH04, HN05 and LHH01. The better comprehensive performance of varieties of the above, the varieties selected for cultivation and promotion of B. variegata varieties provide the parent. The superior plants were selected through the further classification, which were LJC05, LJC01, HLS08, HLS09, HLS05, HLS03, YST01 and YST03. The comprehensive evaluation value of these plants is high, and the selected plants can provide the stock plant for the popularization of new the breed of B. variegata. |
