Embodiment 1

[0023] Parent material A: morning glory (K11-40); round leaves, white flower color, flower shape, trumpet shape;

[0024] Parent material B: morning glory (K11-01L), round leaves, white flower color, flower shape, split petals.

[0025] A kind of breeding method of early flower split petal morning glory, such as figure 1 shown, including the following steps:

[0026] 1. On June 25, 2007, the early-flowering round-leaf morning glory variety (parent material A) was sown; on July 10, the split-petal morning glory (parent material B) was sown. Seedlings were grown in plug trays of the parental material. When the parental material A grew to 6-8 true leaves, it was directly planted in the experimental field, managed in the normal field, and bloomed on August 12 (flowering: for a group, the flowering period also refers to the initial flowering period, that is, 25% of the plants of this population started to flower).

[0027] When the parental material B has 4-6 true leaves, shadin...

Abstract

The invention discloses a breeding method of early blossoming split-petal ipomoea nil. The breeding method comprises the following steps that early blossoming round-leaf l ipomoea nil is used as a parent material A, split-petal ipomoea nil is used as a parent material B, and ipomoea nil hybrid seeds AF1 and BF1 are obtained in two modes of A * B and B * A reciprocal hybridizations respectively; seeds AF2 and BF2 are obtained by adopting two ways of AF1 * B and BF1 * A reciprocal hybridizations; single plants selected from the AF2 are used as female parents and single plants selected from the BF2 are used as male parents to perform cross pollination, and hybrid seeds AF3 are obtained; the seeds AF3 are bagged for selfing, and F4 seeds are obtained; continuous selfing is conducted on the F4 seeds for 3-4 generations, and the stable early blossoming split-petal ipomoea nil is obtained. By the adoption of the breeding method, the stable early blossoming split-petal ipomoea nil can be obtained, grows vigorously, has excellent ornamental characteristics, a flowering period is early, an ornamental period is long, and flowering is 55-65 days earlier than flowering of existing split-petal ipomoea nil varieties in the market at present.
