Problems solved by technology

However, under natural conditions, the maturation time of the pistil and stamen of the same flower is inconsistent, and the flowering time of different varieties of Hippeastrum is also inconsistent. Although the pollen of Hippeastrum can maintain activity for a short period of time, there are still many varieties that are difficult to carry out cross breeding

Embodiment 1

[0014] Take, for example, the vera variety of amaryllis.

[0015] 1. Pollen collection. After the petals of the Hippeastrum variety Vera (Vera) are unfolded, choose a day with fine weather, and pick the whole anther when the anther just cracks and exposes the pollen but does not start to loose powder. At this time, the pollen vitality is the highest.

[0016] 2. Dried pollen. The collected pollen was placed in a silica gel drying dish and dried for 24 hours. During this process, pay attention to ensure that the silica gel is blue, because only blue silica gel has good moisture absorption. In addition, make sure that the anther particles are spread out as much as possible to facilitate drying.

[0017] 3. Pollen storage. Put the dried pollen into a capped centrifuge tube (together with the anthers), and seal it with tape to prevent changes in the environmental humidity during storage from affecting the water content of the pollen, thereby affecting its viability. Store th...

Abstract

The invention discloses a hybrid breeding method of Hippeastrum to solve the non-met flower period in the hybrid course, which is characterized by the following: gathering pollen at flower pesticide splitting without scattering; drying the pollen; sealing; preserving at 4- -40 deg. c; keeping the activity of the pollen; thawing and prewetting the pollen before pollinating to restore and improvethe vitality of pollen; doing artificial pollination for the three-cracked stigma at fine day; connecting a series of nourishing measure to ensure the fruit-forming rate; knowing the affinity of parental generation after one week; maturing the fruit after one month; harvesting the hybrid seed. The invention keeps the pollen activity over one year, which paves basis for variety seed selection of Hippeastrum.

Description

technical field [0001] The invention relates to a method for hybrid breeding of Hippeastrum, which solves the problem that the flowering period does not meet in the hybridization process of Hippeastrum flower varieties, belongs to agricultural biotechnology, and especially belongs to the field of garden plants and ornamental horticulture. Background technique [0002] Hippeastrum (Hippeastrum), also known as Amaryllis, Huazhoulan, Agapanthus, etc., is a perennial herbaceous plant of the genus Amaryllis in the family Amaryllidaceae. It is native to Peru and Brazil and is widely used as an ornamental bulb flower all over the world. During 1912-1949 in our country, there were potted plants of Hippeastrum in Nanjing, Shanghai and other places. In the 1970s, it began to be planted around open gardens in my country as a landscape appreciation. [0003] Hippeastrum is a flower-viewing plant with large, colorful flowers and monoecious flowers. However, under natural conditions, the...
