Chinese scientists have recently developed a robot called GEAIR, the world's first robot which can finish all the steps of plant breeding. This is very important for hybrid breeding.

Hybrid breeding helps plants grow stronger and make more food. Yuan Longping made hybrid rice, and this rice has fed many Chinese people. The hybrid breeding process usually needs workers to remove the stamens(雄蕊) from the female plant first. Then they put pollen(花粉) from the male plant onto the female plant. This way, the new plants can get the best parts from both parent plants. For example, if you mix a male plant that doesn't get sick easily with a female plant that makes lots of fruit, you can get a new plant that has both of these good things.
But hybrid breeding needs workers to do cross-pollination(异花授粉) over and over again in a short time. This work takes lots of time and energy.
GEAIR solves this problem. It uses AI visual recognition and positioning technology to walk among crops. When it finds flowers, it uses robotic arms to do cross-pollination and finish all the work.
Making the robot was not easy. Leaves stand in the way, and flowers are very small. Traditional computer algorithms(算法) can't find them easily in real time. To solve this, the research team trained a new model with a large number of flower pictures. With this model, GEAIR can pollinate each flower in 15 seconds. And the cost is much lower than a worker's yearly pay.
