Germplasm improvement for preharvest sprouting resistance in Chinese white-grained wheat: An overview of the current strategy

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 α-amylase inhibitor gene under a wheat genetic background inhibited α-amylase activity and delayed sprouting. The falling number of six suspected sources, out of 835Chinese leading varieties since 1950', was independent of late maturityα-amylase.
