Embodiment 1

[0023] A kind of plant seed breeding method

[0024] The specific steps are:

[0025] Remove impurities from the plant seeds and clean them. According to the ratio of adding 50 grams of sodium bicarbonate to 1 kg of seeds, add sodium bicarbonate to the seeds, gently rub the seeds to remove the seed coat mucus, then wash the seeds with clean water and wrap them in a damp cloth It is best to germinate at 25°C for 1 day; then dry the seeds and put them into a microwave oven with a rated voltage of 220V, a microwave power of 850W, and a microwave frequency of 2450MHz to treat the soaked seeds twice, 15 seconds each time , with an interval of 20 seconds; then soak the microwave-treated seeds in an ultrasonic cleaner pool with a working frequency of 59kHz and a power of 200W for 2 hours. During the treatment, the water temperature in the cleaner was controlled within 5°C; The seeds were buried in the sandy base soil composed of monazite, bastnaesite, xenotime, lanthanum vanadium al...

[0027] A kind of plant seed breeding method

[0028] Remove impurities from the plant seeds and clean them. According to the ratio of adding 50 grams of sodium bicarbonate to 1 kg of seeds, add sodium bicarbonate to the seeds, gently rub the seeds to remove the seed coat mucus, then wash the seeds with clean water and wrap them in a damp cloth It is best to germinate at 30°C for 2 days; then dry the seeds, put them into a microwave oven with a rated voltage of 220V, a microwave power of 1000W, and a microwave frequency of 2500MHz to treat the soaked seeds twice, 15 seconds each time , with an interval of 20 seconds; then soak the microwave-treated seeds in an ultrasonic cleaner pool with a working frequency of 59kHz and a power of 200W for 2 hours. During the treatment, the water temperature in the cleaner was controlled within 5°C; The seeds were buried in the sandy base soil composed of monazite, bastnaesite, xenotime, lanthanum vanadium allanite, and marble, and the nutrien...

Abstract

The invention discloses a plant seed breeding method. The method utilizes physical mutagenesis to realize plant seed mutagenesis. The method comprises seed immersion, microwave treatment, ultrasonic treatment, foundation soil germination and UV treatment. The seed immersion process comprises mixing plant seeds and sodium bicarbonate, carrying out cleaning by clear water, wrapping the seeds with a wet cloth and carrying out pregermination. The microwave treatment process comprises treating the immersed seeds by a microwave oven. The ultrasonic treatment process comprises treating the seeds subjected to microwave treatment by an ultrasonic cleaner at working frequency of 59kHz and power of 200W. The foundation soil germination process comprises burying the plant seeds subjected to microwave treatment into sandy foundation soil, spraying a nutrient solution 1-2 times every day and keeping the foundation soil wet. The UV treatment process comprises after seed germination, carrying out radiation treatment by a UV lamp three times at time intervals of 7.5h, for 30min every time, until the seedling height is 5cm. The plant seed breeding method can be widely promoted, can realize crop yield increasing and does not change crop product other characteristics.

Description

technical field [0001] The invention belongs to the field of plant breeding, in particular to a plant seed breeding method. Background technique [0002] In the mid-to-late 1990s, my country successfully conducted more than 10 space breeding experiments. A total of more than 70 species of plants and more than 1,000 varieties of plant seeds were tested in space, and the source of radiation mutagenesis was expanded. In recent years, the research on the mechanism of radiation mutagenesis has been vigorously carried out, and the radiation breeding method has been combined with other technologies to improve the effect of radiation mutagenesis. However, most of the current popular breeding methods will cause large-scale changes in the chromosomes of plants, doubling the ploidy of chromosomes, and at the same time, the uncertainty of the products is high, and it is difficult to complete the breeding work for directional purposes, especially for breeding projects that need to increa...
