Abstract: A breeding method for rapidly stabilizing cotton distant hybridization progeny is disclosed. It belongs to the technical field of plant breeding. The disclosure is based on VSG (G. barbadense semi-compatible material) as female parent, general G. hirsutum materials as male parent of the cross to get F1 generation of G. barbadense-G. hirsutum hybrid materials, and treats the F1 generation of young bolls with 0.03-0.05% of colchicine aqueous solution to induce F2 generation to separate the stable intermediate materials or new varieties with excellent genes of both G. barbadense and G. hirsutum, so as to produce new cotton germplasm resources. The main innovation of the present disclosure lies in that it changes the previous treatment position and method of colchicine on cotton plant, and the disclosure is not limited by haploid and directly treats the cotton bolls on F1 cotton plants.

Abstract: A client computing device and a server computing device for federated machine learning. The client computing device is configured to receive a model comprising a set of common layers and a set of client-specific layers from the server computing device. After a training at the client computing device, the set of common layers and the set of client-specific layers are both updated. The set of updated common layers is sent to the server computing device, and the set of updated client-specific layers is stored at the client computing device. The server computing device is configured to receive multiple sets of updated common layers from different client computing devices.
