Abstract: The pre-harvest sprouting resistance （PHS） of 260 wheat （Triticum aestivum L.） germplasm was assessed and Emai 352 was identified with high resistance by 4 years intact spike germination in room. Through the germination test of seed,seed+awn,seed+spike stalk,seed+glumes,it showed that long dormant period,awn,spike stalk and glumes were involved in controlling PHS in Emai 352. Comparison of the PHS of two crossed progeny from Emai 352,the result indicated that it was easy for selecting lines with high PHS and Emai 352 was a good parent for PHS breeding.

Key words: wheat（Triticum aestivum L.）, Emai 352, pre-harvesting sprouting, mechanism of resistance, value
