小麦赤霉病[Gibberella zeae(Schw.)Petch]是长江中下游冬麦区的主要病害,流行频率高,为害损失大,严重影响小麦高产稳产。选育和推广抗病品种是解决病害威胁最经济有效的措施。苏麦3号自1974年育成以来,经国内外学者多年多点鉴定和利用,一致认为不仅对赤霉病抗性强而稳定,而且遗传传递力强,配合力好,是一个小麦赤霉病最优抗源,展示了利用现有抗源,通过杂交育种选育抗赤霉病品种的广阔前景。 Gibberella zeae (Schw.) Petch is the main disease in the winter wheat area in the middle and lower reaches of the Yangtze River. It has high epidemic frequency and large damage and seriously affects the high and stable yield of wheat. Breeding and popularizing disease-resistant varieties is the most economical and effective measure to solve the disease threat. Since its establishment in 1974, Sumai 3 has been identified and utilized by many domestic and foreign scholars for many years. It is agreed that it is not only strong and stable to Fusarium head blight, but also has strong genetic transfer ability and good combining ability. It is a wheat scab The optimal anti-source, demonstrated the broad prospects of the use of existing resistance to breeding anti-scab varieties by cross breeding.
