specific Embodiment approach 1

[0027] It is cultivated by:

[0028] S1: Select a characteristic rice variety as the male parent A, and a restorer rice variety as the female parent B; and select a single plant with excellent breeding in the segregation population;

[0029] S2: Cultivate and hybridize the two selected single rice plants to obtain the first-generation hybrid F1 seed A 1 B 1 F1, screen the hybrid seeds of the F1 generation and cultivate and germinate in the cultivation germination box, select 500-1000 plants for planting and selfing to form the selfing F2 generation A 1 B 1 F2 and inbred F3 generation A 1 B 1 F3;

[0030] S3: Select F3 generation A of the third generation of self-crossing in S2 1 B 1 The plants with excellent characteristics in F3 were crossed with the male parent A to form two F4 generation A 2 B 2 F4, and the F4 generation was self-crossed for two generations to obtain the self-crossed F6 generation A 2 B 2 F6;

[0031] S4: Select the self-crossed F6 generation A ...

specific Embodiment approach 2

[0038] It is cultivated by:

[0039] S1: Select a characteristic rice variety as the male parent A, and a restorer rice variety as the female parent B; and select a single plant with excellent breeding in the segregation population;

[0040] S2: Cultivate and hybridize the two selected single rice plants to obtain the first-generation hybrid F1 seed A 1 B 1 F1, screen the hybrid seeds of the F1 generation and cultivate and germinate in the cultivation germination box, select 500-1000 plants for planting and selfing to form the selfing F2 generation A 1 B 1 F2 and inbred F3 generation A 1 B 1 F3;

[0041] S3: Select F3 generation A of the third generation of self-crossing in S2 1 B 1Plants with excellent characteristics in F3 are crossed with male parent A and F1 generation seed A 1 B 1 A new F41 generation A was formed by crossing the three F1 species for several generations 2 B 2 F41, and the F41 generation was self-crossed for two generations to obtain the self-cr...

specific Embodiment approach 3

[0044] The difference in this embodiment is that the seed soaking gel 9 in the rice breeding germination equipment can be replaced by a cotton bed and a seed soaking water solvent, which is convenient for the circulation and purification of the seed soaking solution, and the cotton bed and seeds are laid layer by layer, so that it can meet Bulk sprouting needs.

Abstract

The invention belongs to the technical field of rice breeding, and particularly relates to a rice breeding method and breeding germination equipment. A sealed top cover is arranged at the top end of acultivation germination box; a light supplementation and heat radiation lamp is fixed at the lower end of the sealed top cover; a ventilation grille is arranged at each of the left side wall and theright side wall of the cultivation germination box; a convex rib rail is arranged at the lower end of the inner side of the cultivation germination box; a cultivation box is movably connected onto theconvex rib rail through cooperation with a clamp groove; a rubber sealing end cap is arranged at the right end of the cultivation box; the rubber sealing end cap and the side wall of the cultivationgermination box maintain sealed connection; and a circulation hole groove is formed in the outer side of the rubber sealing end cap. High-quality varieties of rice after hybridization is subjected torepeated hybridization with characteristic male parents, and is then subjected to selfing to transfer the parental characteristics to new-variety rice, so that the better adaption to growth in complicated environment can be realized. In addition, special fermentation equipment is matched for improving the survival rate of hybridization and selfing.

Description

technical field [0001] The invention belongs to the technical field of rice breeding, and in particular relates to a rice breeding method and breeding germination equipment. Background technique [0002] my country's grain is mainly rice and wheat, of which rice occupies a large part. To increase rice production, it is necessary to strengthen research on rice technology. my country's rice technology has improved significantly in recent years, but there are still some problems that need to be further solved, and these problems have seriously affected the development of my country's rice technology. [0003] Due to the external environment or its own growth factors, rice seeds have long dormancy period, low germination rate, irregular germination and low germination quality, which seriously affect the growth of later crops, and lead to a series of problems such as long production cycle and poor product quality. question. Due to the ubiquity of seeds carrying bacteria and phy...
