Title:
MOLECULAR MARKER OF GENE RELATED TO DOMINANT EARLY HEADING IN RICE MATERIAL CAPABLE OF EARLY HEADING WITHOUT DECREASING YIELD, AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2022/056767
Kind Code:
A1
Abstract:
The specific primer ZMEH_1 that is used to identify or assist in identifying the heading date of rice material is a pair of PCR primers corresponding to the upstream and downstream of the sequence differential fragment 1, which is between the late-heading parent MH63 and the early-heading parent DEH229, of the Os03g0122600 gene of rice. ZMEH_1 can interpret approximately 86.0% of the phenotypic variation from the MH63/DEH229 progeny population, and satisfies the requirements for industrial application. Rice variety DEH229 has the characteristic of early heading without decreasing yield, and progenies derived from the rice variety DEH229 and a plurality of rice varieties all continue to have the characteristic of early heading without decreasing yield. The specific primer ZMEH_1 can be used to rapidly screen out material with the characteristic of early heading from rice material of the progenies derived from DEH229 so as to perform rapid selective breeding and utilization, and promote the breeding process of early-maturing rice without affecting the grain yield.
