Embodiment Construction

[0021] The present invention will be further described in detail below in conjunction with the examples.

[0022] When the present invention is concretely implemented, the tulip commercial variety breeding work is carried out in the tulip garden of Changchun Park and the Nong'an nursery stock production base respectively. Choose varieties with high overwintering survival rate, neat plant height, neat flowering period, long post-flowering growth time, and large number of seed balls, while considering ornamental value such as flower shape and color. At least 50-100 bulbs are planted for each variety (the number of bulbs planted in tulip gardens is much higher than 100 due to landscape requirements). The row spacing between plants is 15×25cm, and the depth is 10-15cm.

[0023] Routine water and fertilizer management, and at the same time set up different heat preservation measures (frozen water, heat preservation layer) in the open field, and use the survival rate as the main in...

Abstract

The invention relates to a method for variety domestication and seed breeding of Tulipa gesneriana L.. The method includes the following operation steps: initial seed selection, planting management, variety optimization, pollen collection, cross pollination, isolation and labeling, record and observation and measurement analysis, wherein measurement analysis includes the steps: adopting a gradingmethod according to international standards, taking 5 grades of bulbs as research objects, performing shading treatment, preparing a soil substrate, taking fertilization treatment measures, arrangingplanting density, and measuring the growth rate, reproductive performance and flowering characteristics of the different grades of the bulbs. The shortcomings in the prior art are overcome, the excellent seed breeding method is selected, excellent new varieties with stable inheritance can be obtained effectively, and the seed breeding period is shortened.

Description

technical field [0001] The invention relates to the technical field of planting and breeding, in particular to a method for domesticating and breeding tulip varieties. Background technique [0002] Tulip, also known as foreign lotus, is a perennial bulbous herbaceous flower of the monocot Liliaceae, usually with 3-5 leaves, and a few species have 1 or more; the leaves are born in the lower middle part of the stem; broadly lanceolate and full ovate lanceolate The leaves are broadly ovate at the base and long and acuminate above; thick and juicy; there is a light blue-gray waxy layer on the surface. Some wild species and garden varieties have purple-brown or reddish-brown spots or stripes on the leaves. [0003] Tulip stems are upright, smooth, covered with white powder, emerald green. Bulbs flat-conical, with a layer of light yellow or brown on the surface; brown dry membranous pseudobulbs. The bulb consists of 3-5 fleshy scales. The diameter of the bulb is 1-5cm, dependi...
