Abstract

The invention belongs to the technical field of plant artificial hybrid breeding, and relates to a high-efficiency lotus hybrid breeding method. The purpose is to solve the problems that the prior art operation process is time-consuming and labor-intensive, and the stigma is easily damaged. The present invention comprises the following steps: (1) selection of hybrid parental parent: 1. select the female parent that meets the breeding target traits, 2. select the male parent that is complementary to the female parent in terms of traits and phenotypes; (2) the male parent is bagged: give The buds of the male parent are bagged; (3) Collect pollen: collect the stamens of the male parent in a plastic cup, add an appropriate amount of pure water, and stir to prepare a pollen solution; (4) Pollination: absorb the pollen solution and drop the pollen solution in the plastic cup. A little pollen solution is accumulated on the stigma of the female parent or on the lotus plant and shaken back and forth; then bagging, and the bag is removed after pollination is completed; (5) Marking: mark the parental information on the sign. The pollination method used in the invention has low technical requirements for pollination, high pollination success rate, and greatly reduces the cost of artificial pollination.
