| Abstract: |
| To understand the distribution of pre\|harvest sprouting in new bread wheat cultivars from the Huanghuai southern region, this study used a total of 593 newly cultivated wheat varieties as test materials. The seed germination index method and spike germination were employed to evaluate the resistance of these cultivars to pre\|harvest sprouting. The experiment demonstrated variation in resistance to pre\|harvest sprouting among the tested materials. 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’, exhibited moderate resistance to both spike and seed germination. Five cultivars showed resistance spike germination, including ‘Jimai 212’, ‘Xinong 733’, ‘Xinong 633’, ‘Baofeng 1530’ and ‘Jimai 44’, 39 cultivars exhibited moderate 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. |
