Wheat multi-mutation breeding method
A technology for mutation breeding and wheat seeds, applied in the directions of botanical equipment and methods, applications, and plant genetic improvement, can solve the problems of low mutation rate of wheat breeding, difficult to grow into new individuals, weak competitiveness, etc., and achieve shortened breeding. Years, fast and efficient breeding, the effect of increasing the probability

Embodiment 1
[0023] A method for multiple mutation breeding of wheat, comprising the steps of:
[0024] Step 1: Under the condition of selecting the disease-susceptibility, prepare alternative wheat seeds, make the wheat grow under the disease-sensitivity condition, be the F1 generation seed with the seed of natural wild wheat, pass through the X-ray dose of 30,000 roentgens to the F1 generation seed Irradiate for 3 seconds;
[0025] Step 2: Plant the F1 generation seeds after X-ray irradiation for at least two generations, use the obtained wheat seeds as the male parent, select a high-yielding and stable-yielding wheat variety as the female parent, and carry out hybrid planting to harvest high-yield and neat wheat ears. For F2 generation seeds, the female parent of wheat removes the stamens and immature anthers of the female parent of wheat at 10 o'clock every morning during its flowering period, and wraps the flower of the female parent of wheat with a paper bag. The two ends of the pape...

[0035] Step 2: Plant the F1 generation seeds after X-ray irradiation for at least two generations, use the obtained wheat seeds as the male parent, select a high-yielding and stable-yielding wheat variety as the female parent, and carry out hybrid planting to harvest high-yield and neat wheat ears. For F2 generation seeds, the female parent of wheat removes the stamens and immature anthers of the female parent of wheat during its flowering period every day at 11 o'clock in the morning, and wraps the flower of the female parent of wheat with a paper bag.
