Abstract

The invention discloses a breeding method of supersulcus-leaf Brassica oleracea var. acephala f. tricolor Hort., which comprises the following steps: carrying out inbred purification on collard species 'white peacock' to obtain white partite-leaf collard inbred line Y316, and hybridizing by using Y316 as a male parent and cabbage cytoplast male sterile material C-12 as a female parent; backcrossing with the original male parent by selecting an individual plant, which has the closest characters with the male parent, from filial generation as the female parent; repeating the second step, and continuously backcrossing to obtain white partite-leaf collard male sterile line CMS316; and carrying out inbred purification on the collard species 'red pigeon' to obtain red roundleaf collard inbred line Y438, and hybridizing by using Y438 as the male parent and the white partite-leaf collard male sterile line CMS316 as the female parent to obtain the supersulcus-leaf Brassica oleracea var. acephala f. tricolor Hort. hybrid. The new hybrid species obtained by the method disclosed by the invention has the advantages of high ornamental value, long ornamental period, cold resistance and disease resistance.

Description

technical field

[0001] The invention belongs to the technical field of plant cultivation, and in particular relates to a breeding method of lobed leaf ornamental kale. technical background

[0002] Ornamental kale (Brassica oleracea var.acephala f.tricolor H or t.) is a variety of Brassica oleracea species in the genus Brassica, native to the European Mediterranean to the North Sea coast, biennial herb, mainly for foliage, its leaves The shape is beautiful and changeable, the heart and leaves are colorful like flowers, and the cold resistance is strong. It is the first choice for viewing in late autumn, winter and early spring, and has high ornamental value and economic benefits.

[0003] Kale is a typical cross-pollination crop with obvious heterosis. The utilization of heterosis is one of the fast and effective ways to breed new varieties of kale.

[0004] Most of the cabbage varieties currently on the market are hybrids prepared from self-incompatible lines, especially t...

Embodiment 1

[0035] Material:

[0036] Cabbage cytoplasmic male sterile material C-12 (also known as Zhonggan No. 22, produced by the Vegetable and Flower Research Institute of the Chinese Academy of Agricultural Sciences); imported ornamental kale varieties "White Peacock" and "Red Pigeon" can be purchased from Zhejiang Hongyue Flower Ltd.

[0037] Before breeding, the kale variety "White Peacock" was purified through continuous self-fertilization and directional selection for at least five generations (each generation selects and targets traits (including plant type, leaf type, outer leaf color, heart leaf color, plant expansion) The closest single plant selfing), obtained an ornamental kale inbred line with stable botanical characteristics, good combining ability, and large pollen amount, named the white deep-leaved kale inbred line Y316, the main characteristics of the inbred line See Table 1.

[0038] The kale variety "Red Pigeon" was purified through continuous self-fertilization a...
