【Objective】 The CIMMYT wheat cultivar Saar has exhibited a high level of adult-plant resistance to leaf rust, stripe rust and powdery mildew in Europe, Asia, and South America, and identification of its QTL for leaf rust resistance will play an important role in breeding wheat cultivars for durable resistance.
【目的】小麦品种Saar由CIMMYT育成,在欧洲、亚洲和南美洲对小麦叶锈、条锈和白粉病均表现出很高的成株抗性,发掘其成株抗叶锈QTL对于选育持久抗锈品种有重要作用。

茶树抗性育种
resistance breeding of tea plant
茶树抗性育种(resistanee breeding(,ftea plant)一种以选育杭性强的茶树新品种为主要目标的育种方法,包括抗病、杭虫以及抗早、杭寒等不利于茶树正常生长的外界因子的抵抗能力。中l月北方茶区里季多低湿干旱,冬季多低沮严寒,这个地区的茶树选种不仅要求优质高产,还必须有较好的耐旱和抗寒能力:中国南方茶区气候沮吸很润,利于某些病虫发生.所以在南部茶区必须l视茶树抗病和杭虫能力的育种。无沦南北茶区,都要咬视免疫品种的选育。 茶树抗性育种要从以下几个方面扮手:声“‘泛搜集国内外的抗源品种和野生种,建立抗病虫的种质库.利用现代化的人工气候,加速进行病虫人工诱发和鉴定:寻求茶树本身能抑制病虫生长的化学物质,并加以棋拟仿制;研究人工免疫和人造抗病性的技术等。但杭性与某些经济性状间存在着连锁关系.在育种目标日益全面要求下.在利用新类型亲本和新抗源时,必须密切注意它们带来的不良性状.打破抗性与不良性状的连锁.才能获得理想的结果。以西维时)
