根据1943年以来在我国主要梅花产区进行品种胡查记载的结果，并与梅花品种的历史发展过程相核对，作者认为应在梅花品种分类中，主要根据进化的观点，同时也须结合园林栽培应用上的需要。这是梅花品种分类的基本原则，也可在其他花卉的品种分类研究中结合具体情况推广应用。在进行梅花品种分类时，作者根据上述原则，用枝条姿态作为梅花品种分类的第一般标准，花型作为第二极标准，再参照其他各级标准，初步提出了中国梅花品种分类系统的建议，并将业已记载、整理的231个梅花品种分列归入此系统中。

梅花（Prunus mume Sieb.et Zucc.）是我国原产的著名花木，已有二千年以上的栽培历史。通过有关文献资料的整理分析以及实地的调查研究，本文着重对梅之原产地及梅花栽培历史作一初步探计。著者认为梅之原产地系以川、鄂山区为中心，梅花的栽培亦由四川开始，大致分五个时期，不断向三面扩展，逐渐增加品种并提高栽培水平和规模，文章讨论了梅花品种的演化，文学艺术与梅花栽培以及引种驯化等问题。

Beginnig in autumn of 1961, Chen and his colleague crossed 3 hardy, wild Dendranthema species (D. indicum var. acutum, D. chanetii and D. lavendulifolium). with some early chrysanthemum cultivars (D. x grandora). During 1962-1963, we selected twice by giving points of evaluation by experts, resulting in 13 qvs. of the Rock Daisy ("Hong Yan", etc.) selected and named. Butextention and research work was dropped during the "Cultural Revolutions" for more than 10 years after 1965. In 1981, we continued the research work of chrysanthemum breeding by giving lectures and making practises. But studies on breeding Dibeiju or Ground-Cover Chrysanthemums were really carried on after 1984 by the authors (Chen et al.). For instance, D.vestitum, one of the most important pqrents in distant crossing, was discovered in large areas and introduced by the first author from Tian Ju Shah of Anhui Province (1984); "Mei Ai Fen" was selected out from early chrysanthemum mixed seedlings by him (1984); the aim of breeding adjusted (Chen et al., 1985); the research project supported by Beijing Committee of Science and Technology (1987); and the cultivar group name Dibeiju (Ground-Cover Chrysanthemum) appointed and used. (Chen et al., 1987) During recent 6 years (1987-1993), 5 batches of Dibeiju new cvs. have been bred and distributed for extension. Over 5 000 000 plants of it have been in cultivation in whole China until the end of June 1993.
