The present disclosure relates to a fertility gene and the use thereof, and relates to the biotechnology field, particularly to a method of plant hybrid breeding including creation of a sterile line and preparation of hybrid seeds, more particularly to a fertility gene FL2, a mutant thereof and use thereof in hybrid breeding.

Fertility gene and use thereof

The present disclosure relates to an expression vector for restoring male sterility in a plant. The expression vector comprises a regulatory region sequence operably linked to a heterologous nucleotide sequence.

The present invention provides a rice whole genome breeding chip and the application thereof. The rice whole genome breeding chip of the present invention is Rice60K, an SNP chip manufactured based on Infinium technique. Each chip can detect 24 samples simultaneously and contains 58,290 SNP sites. The marker sites have DNA sequences represented by SEQ ID NO.1-58290. The chip can be used in molecular marker fingerprint analysis of the rice variety resources, in genotype identification of the hybrid progeny population, in identification of the variety authenticity, in analysis and screening of the genetic background of the breeding materials, and in association analysis of the agronomic traits, having wide application prospects.
