Description

technical field

[0001] The present invention relates to a method for improving the breeding efficiency of rice herbicide resistance, and more specifically relates to a method for inducing a chlorsulfuron-resistant somatic mutant in rice. A practical approach to plant cell engineering for the herbicide novel variety pathway. Background technique

[0002] With the rapid development of agricultural herbicides, the safety of herbicide use has become increasingly prominent, which has attracted widespread attention. Starting from the improvement of herbicides, the continuous introduction of new varieties of high-efficiency, low-toxicity, and low-residue herbicides is a good way to solve the problem. , but requires huge investment, and its research cycle is long; in addition, rice is extremely sensitive to chlorsulfuron herbicide, and the content of chlorsulfuron in soil is 0.1-0.2Γ—10 -9 When the growth of rice plants is inhibited, the plants will b...
