小麦赤霉病是长江中下游麦区的主要病害,它不仅造成严重减产,而且降低籽粒品质,从而影响利用价值,因此选育抗赤霉病品种是本地区小麦育种主要目标之一。关于小麦赤霉病遗传和抗赤育种研究,已有许多报道。但小麦抗赤霉病育种难度大,进展慢。面对这个难题,我们从80年代初调整了育种目标和策略,近几年先后育成温麦8号、温麦10号及温90鉴10等三个小麦新品种(系),这些材料1988年冬开始相继参加三轮省区试,表现抗赤性均达中抗水平,综合性状好,增产显著。本文就现有研究进展,谈谈我们的初步认识。
Wheat head blight is the main disease in the wheat area in the middle and lower reaches of the Yangtze River. It not only causes serious yield loss, but also reduces grain quality, thus affecting the utilization value. Therefore, breeding of scab varieties is one of the main objectives of wheat breeding in this region. There have been many reports on the genetic and anti-red breeding of wheat scab. However, the breeding of wheat scab resistance is difficult and slow progress. Faced with this challenge, we adjusted the breeding objectives and strategies from the early 1980s. In recent years, we have successfully cultivated three new wheat varieties (Wenmai 8, Wenmai 10 and Wen 90 Jian 10) in 1988 Winter began to participate in the three rounds of provincial tests, the performance of anti-redness reached the level of resistance, good overall performance, yield significant. This article is about the progress of the existing research and about our preliminary understanding.
