Continuous recessive character backcrossing technology

The invention discloses a continuous recessive character backcrossing technology which is characterized by taking a material which contains no target recessive genes and is ready to be improved as a recurrent parent, and taking a material which contains the target recessive genes as a donor parent; taking the recurrent parent as the parent to be hybridized with the donor parent and harvesting hybrid seeds of the first generation F1 and recurrent parent seeds; and planting the hybrid seeds of the first generation F1 and the recurrent parent seeds till the planting of a group containing backcross hybrid seeds of the second of n generations BCn F2 and till the typing into a target recessive gene isogenic line of the recurrent parent. The invention also discloses a method for creating a purpleleaf marker isogenic line by applying the continuous recessive character backcrossing technology and also a method for transferring new purple leaf marker nucleus sterile line by taking the purple leaf marker isogenic line as an intermediate material. In the methods, a selfing process is combined with a next backcrossing process for the treatment in one season, therefore, the time efficiency is improved by about 50 percent, a small number of dominant-gene-controlled unsuitable characters of existing fine-quality parents can be fast improved, and useful recessive characters can be fast imported to the present high-level heredity background.
