根据我们对不结球白菜品种的形态学特征和生物学特性的研究,依各品种在植物学分类中的地位、主要生物学特性与栽培特点、形态学特征的三级分类标准,提出了不结球白菜品种的园艺学分类法。认为我国的不结球白菜均属于芸苔属的芸苔种的一个亚种Brassica campestris ssp.chinensis,其下共有六个变种(varieties):(1)普通白菜类var.communis Tsen et Lee(var.erecta Mao);(2)塌苯类var.rosularis Tsen et Lee(var.atrovirens Mao);(3)菜苔类var.tsaitai Hort.(var.purpurea Mao);(4)苔菜类var.tai-tsai Hort;(5)多头菜类var.multiceps Hort.(var.nipponsinica Hort.);(6)油菜类var.utilis Tsen et Lee(var.oleifera Makino)。每一类型(变种)下,又根据品种的发育和生态特性、栽培特点和形态特征分为若干种类。此分类法可为不结球白菜种质资源的进一步研究和有效利用提供科学依据。
According to our research on the morphological and biological characteristics of non-heading Chinese cabbage varieties, according to the classification of each species in the botanical classification, the main biological characteristics and cultivation characteristics, the morphological characteristics of the three-class classification criteria, not Horticultural taxonomy of cabbage varieties. It is considered that all the non-heading Chinese cabbage belongs to Brassica campestris ssp.chinensis, a Brassica campestris ssp.chinensis belonging to the Brassica genus, under which there are six varieties: (1) the common cabbage var.communis Tsen et Lee (var (3) Cassia var. tsaitai Hort. (var. purpurea Mao); (4) Cassia var. tai-tsai Hort; (5) var.multiceps Hort. (var. nipponsinica Hort.); (6) rape var.utilis Tsen et Lee (var.oleifera Makino). Each type (variety), but also according to species development and ecological characteristics, cultivation characteristics and morphological characteristics are divided into several categories. This taxonomy can provide a scientific basis for further research and effective utilization of non-heading Chinese cabbage germplasm resources.
