摘要: Most modern white-grained wheat (Triticum aestivum L.) cultivars in China lack sprouting resistance. Some white grain varieties showed lower preharvest sprouting percentage in different years. Tolerance to sprouting in most cultivars comes from the varieties, Wanxian White, Fulingxuxu White, Suiningtuotuo, and Yongchuan White. The alpha-amylase inhibitor gene under a wheat genetic background inhibited alpha-amylase activity and delayed sprouting. The falling number of six suspected sources, out of 835 Chinese leading varieties since 1950', was independent of late maturity alpha-amylase.
