Embodiment 1

[0032] A kind of intelligent hybrid breeding method comprises the following steps:

[0033] (1) Selection of female parent material: according to the breeding improvement goal, select the inflorescence of the full-flowering stage of the high-yield intelligence that has corresponding characters and grow robustly as the female parent material, and in the cloudy or sunny afternoon of the day before pollination, remove all the inflorescences on the female parent inflorescence. Open flowers, young fruit and the top part, leave the flowers that are about to open the next day, gently push the petals, emasculate, bag and list.

[0034] (2) Selection of the male parent material: according to the breeding improvement goal, select the inflorescence of the full-blooming stage of the high-yield intelligence that has corresponding traits and grows robustly as the male parent material, and the flower that has opened is removed on a cloudy or sunny afternoon the day before the pollen collectio...

Embodiment 2

[0040] (1) Selection of parent material: same as Example 1.

[0041] (2) Selection of male parent material: same as in Example 1.

[0042] (3) Pollen collection: In the morning of the next day, collect the pollen of the flowers that had been bagged from the male parent within 24 hours, brush the pollen from the male parent into a clean glass petri dish with a brush, and place it in a cool place for use as needed.

[0043] (4) Pollination: 8:00 to 11:00 on a windless and sunny day. Before pollination, smear the stigma of the female parent with 10mg / L 2,4-D solution, and pass the collected fresh male parent puzzle pollen through a brush Gently smear it on the stigma of the female parent, repeat the pollination twice, bag it after pollination, and put a tag on it.

[0044] (5) Fruit development management: same as embodiment 1.

[0045] (6) hybrid harvest and sowing: with embodiment 1.

Embodiment 3

[0047] (1) Selection of parent material: same as Example 1.

[0048] (2) Selection of male parent material: same as in Example 1.

[0049] (3) Pollen collection: In the morning of the next day, collect the pollen of the flowers that had been bagged from the male parent within 24 hours, brush the pollen from the male parent into a clean glass petri dish with a brush, and place it in a cool place for use as needed.

[0050] (4) Pollination: 8:00-11:00 on a windless and sunny day. Before pollination, smear the stigma of the female parent with 15mg / L 2,4-D solution, and pass the fresh collected pollen of the male parent through a brush Gently smear it on the stigma of the female parent, repeat the pollination twice, bag it after pollination, and put a tag on it.

[0051] (5) Fruit development management: same as embodiment 1.

[0052] (6) hybrid harvest and sowing: with embodiment 1.

Abstract

The invention discloses a crossbreeding method for alpinia oxyphylla. Relates to the technical field of agricultural breeding. Comprising the following steps: selecting a female parent / male parent material; collecting pollen; performing pollination; fruit development management; hybrid harvesting and sowing. According to the breeding and production requirements, a breeding method system is innovated, materials with different excellent characters are created, excellent new varieties which are suitable for different production purposes and have specific excellent characters are bred, the number of fruits and the hybridization setting rate are further increased, and the healthy development of the industry is promoted.

Description

technical field [0001] The invention relates to the technical field of agricultural breeding, and more specifically relates to a method for intelligence-enhancing cross-breeding. Background technique [0002] Alpinia oxyphylla Miq. is a perennial herbaceous plant of the genus Alpinia in the family Zingiberaceae. The dried ripe fruit is used as medicine. [0003] Yizhi is one of the four famous southern medicines in my country, and it is also an important medicinal and food homologous crop. It is widely used in Chinese patent medicines, health products, leisure foods, condiments, etc. As a special product and an important undergrowth economic crop in Hainan, Yizhi is the undergrowth economic crop with the largest planting area in Hainan, and has broad development prospects. In recent years, the increase in demand has led to a continuous increase in the planting area of ​​edulis. [0004] At present, there are only two varieties of Yizhi. A single variety is not conducive to...
