Embodiment 1

[0033] 1. Select grain seeds: select 100 seeds of full-bodied basmati rice and high-quality millet, keep them moist and accelerate germination.

[0034] 2. Seed pendulum shape: Prepare a round pot with a diameter of 25-30 cm, fill it with moist fine sand, and sow the germinated seeds in a group of 10 seeds into a pyramid shape. A pot consists of eight pyramid shapes. It is convenient to record radiation at different times.

[0035] 3. Seed radiation: When the bud valley grows to 1-5 cm, use a magnifying glass to focus on the large sun energy focus to radiate the base of the bud. The radiation is carried out in three steps: lightly irradiate for 30 seconds with a focus as large as a broad bean; The focus of heavy processing is reduced to the size of a watermelon seed for 30 seconds; the third step is intensive processing, the focus is reduced to the size of a soybean, and it stops when there is a slight gas; two drops of mineral water are instilled after each completion, Just ...

Embodiment 2

[0040] 1. Select grain seeds: Screen 100 seeds of plump wild rice and keep them moist to accelerate germination.

[0041] 2. Seed pendulum shape: Prepare a round pot with a diameter of 25-30 cm, fill it with moist fine sand, and sow the germinated seeds in a group of 10 seeds into a pyramid shape. A pot consists of eight pyramid shapes. It is convenient to record radiation at different times.

[0042] 3. Seed radiation: When the bud valley grows to 1-5 cm, use a magnifying glass to focus on the large sun energy focus to radiate the base of the bud. The radiation is carried out in three steps: lightly irradiate for 30 seconds with a focus as large as a broad bean; The focus of heavy processing is reduced to the size of a watermelon seed for 30 seconds; the third step is intensive processing, the focus is reduced to the size of a soybean, and it stops when there is a slight gas; two drops of mineral water are instilled after each completion, Just moisten the sprouts.

Abstract

The invention relates to a method for maintaining rapid advantages of variant lines stable with solar energy focal radiation on sprout grains. The method specially comprises the following steps: selecting grain seeds; performing moistening and sprouting; placing the seeds in a certain shape; performing dibble seeding in a pyramid shape; performing radiation on the seeds in three steps; performing optimization on plants; performing backcrossing; obtaining advantage polymerization. The method disclosed by the invention is implemented, the technology is simple, the operation is easy, and only simple appliances including magnifying glass and the like are needed; but the variant probability is high, and the rapid advantages of the variant lines are maintained stable. The method disclosed by the invention is implemented, the first generation varies, and the variation rate reaches 15% or above. Sterile plants appearing in the method provide a new way for cultivating novel female parents. Besides, after backcrossing, new varieties are bred, and have the advantages of lodging resistance, high temperature resistance, broad adaptability, steady yield, and excellent color, fragrance and taste of rice. The yield of cultivated saline-alkaline resistant two-line sterile lines and the yield of early-maturing conventional rice, mid-maturing conventional rice and late-maturing conventional rice are increased by 2 times or above than that of original seawater rice. The bred three-line sterile lines have the characteristics and the functions that steamed red rice, steamed black rice and steamed brown rice are fragrant and soft, and steamed rice does not become hard after being put for a night.

Description

technical field [0001] The invention relates to the field of a new technology for cultivating new rice varieties, in particular to a method for maintaining the rapid superiority and stability of mutated strains by utilizing solar focus to radiate buds and valleys. Background technique [0002] Using mutants to study and obtain some genes related to plant growth, development and other traits is one of the important molecular genetic research methods, and is currently being widely used by scholars engaged in basic research. The use of mutagenesis technology to breed rice breeding is a resource innovation and effective method. [0003] Learned from related literature. At present, the mutagenesis techniques used in rice breeding mainly include high pressure mutagenesis, radiation mutagenesis, ion implantation rice mutagenesis, space mutagenesis and other methods. [0004] The seeds were subjected to 75-78Mpa pressure treatment, and the pressure deformation effect of high press...
