The present application relates to the field of agricultural technology, in particular to a plant temperature-sensitive male sterility gene mutant tms17 and application thereof.The nucleotide sequence of the plant temperature-sensitive male sterility gene mutant tms17 comprises the nucleotide sequence shown in SEQ ID NO.1 in the sequence listing.The present application screens a new temperature-sensitive male sterile line tms17 by chemical mutagen ethyl methyl sulfone (EMS) mutagenesis of japonica rice variety ZH11, which is completely sterile at high temperature and fertility is restored at low temperature, and the mechanism of temperature-sensitive fertility restoration is disclosed, which provides a new germplasm resource with application potential for rice two-line hybrid breeding.

The invention provides methods for mutagenizing plants or parts thereof, comprising subjecting a plant tissue to illumination with UV light followed by treatment with a chemical mutagen. The methods may advantageously be applied to methods of identifying a plant of a predefined species carrying one or more predetermined mutation(s) in nucleotide(s) of interest [NOI(s)], in a target sequence.
