MOLECULAR MARKERS OF PHOTO-SENSITIVITY MODULE RELATED TO RICE BLAST RESISTANCE AND THEIR APPLICATIONS - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240218459 titled 'MOLECULAR MARKERS OF PHOTO-SENSITIVITY MODULE RELATED TO RICE BLAST RESISTANCE AND THEIR APPLICATIONS

The invention described in this patent application involves genetic analysis and the development of a marker set for a photo-sensitivity module related to transgressive photo-sensitivity (TPS) in rice blast resistance breeding.

• Genetic analysis was conducted using bi-parental RIL populations derived from TPS crosses with a donor parent to map the photo-sensitivity module [qhd6+qhd7] under both long-day (LD) and short-day (SD) conditions.
• The molecular marker set proposed by this invention allows breeders to predict the degree of TPS in northern early rice progenies derived from crosses with the donor parent, aiding in parental selection and screening progenies with strong TPS in blast-resistant biotechnology breeding schemes.

Original Abstract Submitted

this invention describes a work including both genetic analysis and development of a marker set for a photo-sensitivity module underlying transgressive photo-sensitivity (tps) phenomenon found in the breeding improvement of rice blast resistance by the introduction of gene, belonging to the field of rice molecular genetics and biotechnology breeding. by using bi-parental ril populations derived from tps crosses with a donor as one parent, genetic analysis has been carried out to map the photo-sensitivity module [qhd6+qhd7] under both long-day (ld) and short-day (sd) conditions. with the aid of the molecular marker set proposed by this invention for this module, breeders can predict the degree of tps in northern early rice progenies derived from crosses with donor as one parent when they are doing parental selection or screening progenies carrying without strong tps in blast-resistant biotechnology breeding schemes.
