Proposal of updated XYZ system for the production of hybrid wheat seedShort Communication

The following updates have been proposed for the XYZ system for the production of hybrid wheat: The waxy characteristics of the grain were used as a classifying mark. The candidate pollen sterility gene TIP2 was detected in silico based on similarity to known pollen sterility genes in rice. In order to maintain a sterile maternal component, the addition chromosome 7H was proposed, carrying wild-type alleles Waxy-H and TIP2-H. The concept of practical production of the commercial F1 seed was designed.

Keywords: heterosis; male sterility; waxy
