Abstract:

The present research aimed to study the inheritance and chromosomal location of a photoperiod-thermo sensitive male sterility (PTSMS) gene in Xinong 291S (XN291S), which is a new PTSMS wheat line. The inheritance was studied in F1 and F2 populations derived from crosses between XN291S and eight wheat cultivars. All F1 plants were fertile and the F2 populations segregated in either 15 : 1 or 3 : 1 fertile : sterile ratios indicating that PTSMS was controlled by one or two recessive major genes. Five wheat cultivars carried homozygous dominant alleles for fertility, whereas the other three, including ‘Chinese Spring’ (CS), carried a single homozygous dominant allele. Chromosomal location of the PTSMS gene was studied by crossing a set of CS nulli-tetrasomic lines to XN291S. Self-fertility of F1 hybrids XN291S/N5BT5A and XN291S/N5BT5D were significantly lower than the others. Therefore, the PTSMS gene in XN291S that differed from CS was located on chromosome 5B. Location of the second PTSMS gene needs further study.
