Radioactive breeding

Radiation breeding is a novel cultivation technique developed in recent years. Improve crop mutation rate < the radiation breeding by utilizing various rays, such as X-ray, neutron irradiation of crop seed, plant or some organs and tissues. Make it happen all kinds of variation, and then select the genetic variation in need of excellent, bred varieties. After this is planted, a green pepper weight can be up to 500 grams, corn can be carried out seven bar, cucumber can grow to half a meter high, and the beauty of the flowers also fabulous to mutate, a bunch of red "is the string to blossom, here can full flowering, like a tower. This is the four single "marigold petals, and flowers became six petal flower layers. Petunia "will be from the original open red flowers, cultivate the flower becomes large, and a strain can blossom with red, white, pink and other colors.

Ray irradiated seed

With high energy and strong penetration of X-ray irradiated seeds can be the seed cells within the chromosome breakage, its location, structure, and molecular genetic changes. And crops of various characteristics are determined by the chromosome genetic and molecular so ray irradiation the seed cell chromosome genetic changes occur as a result of, will lead to the change of the characteristic of living organisms. On the other hand, the radiation can also cause the genetic variation in the cytoplasm. The convergence of the two kinds of function makes the radiation breeding have the characteristic of singularity.

Improve crop mutation rate

Use of radiation breeding, can make crop mutation rate is hundreds of times higher than that of natural variability to thousands of times, and variation is varied in a very wide range. And be able to generate many new varieties through the various kinds of variation. For example, with ray irradiation of the castor oil plant, growth period can be shortened from the original 270 days to 120 days, the formation of new varieties of short growth. Radiation breeding can change crop varieties single benign to overcome the shortcomings of the original variety, can also cause variation of stabilise soon, greatly shorten the breeding process. In addition, radiation breeding operation is simple, as long as the seed or plant near irradiation in the X-ray source, you can achieve the desired effect can used alone can also and other breeding technology combination, to achieve better results.
