WSVAS: A YOLOv4 -based phenotyping platform for automatically detecting the salt tolerance of wheat based on seed germination vigour.Salt stress is one of the major environmental stress factors that affect and limit wheat production worldwide.  We developed the Wheat Seed Vigour Assessment System (WSVAS), which enables rapid and accurate detection of wheat seed germination using the lightweight convolutional neural network YOLOv4.  The WSVAS system can automatically acquire, process and analyse image data of wheat varieties to evaluate the response of wheat seeds to salt stress under controlled environments.  The WSVAS image acquisition system was set up to continuously acquire images of seeds of four wheat varieties under three types of salt stress.  In this paper, we verified the accuracy of WSVAS by comparing manual scoring.  WSVAS can quantify plant stress caused by salt stress and provides a powerful tool for salt-tolerant wheat breeding.
