pss1 is a recessive nuclear gene. Its phenotype includes pollen semi-sterility and anther indehiscence that is unaffected by growth duration. The female gamete is normal.
Curator Comment
In the F2 population derived from the two parents W207-2 and Dular, pss1 was mapped to an interval on chromosome 8 defined by the two SSR loci RM6356 and RS41. In Gramene the pss1 was mapped between RM151 and RM6356 on various maps because RS41 was not mapped on those maps.
