To understand the distribution of pre-harvest sprouting in new bread wheat cultivars from the Huan-ghuai southern region,this study used a total of 593 newly cultivated wheat varieties as test materials.The seed ger-mination index method and spike germination were employed to evaluate the resistance of these cultivars to pre-har-vest sprouting.The experiment demonstrated variation in resistance to pre-harvest sprouting among the tested materi-als.Susceptible and highly susceptible types were predominant,while the proportion of resistant varieties had been increasing year by year from 5.4％to 19.4％.Selected cultivars,such as'Xumai 0054'and'Huaimai 4046',exhib-ited moderate resistance to both spike and seed germination.Five cultivars showed resistance spike germination,in-cluding'Jimai 212','Xinong 733','Xinong 633','Baofeng 1530'and'Jimai 44',39 cultivars exhibited mod-erate resistance,such as'Xinong 528'and'Longke 1221',and 16 cultivars had low field-intact spike germination rates.These results provide valuable germplasms resources for breeding new cultivars resistant to spike germination.
