摘  要：
云南小麦(Triticum aestivum ssp yunnanense King)产于云南省澜沧江、怒江下游.为云南省所特有,具有护颖坚硬、极难脱粒、穗轴受压力易折断等原始特性,又有耐瘠薄、抗旱、抗穗发芽、抗鸟害等多种优点。本文研究了云南小麦的苗期和成株期抗旱性。结果表明云南小麦的苗期抗旱性在不同品种间存在较大差异,但均不及云南普通小麦地方品种油榨地光头麦;而澜沧铁壳麦和永德铁壳麦的苗期抗旱性强于育成品种云麦42。云南小麦具有较强的成株期抗干旱能力,不同品种间差异不明显,其中云县铁壳麦超过油榨地光头麦,其它品种与育成品种云麦42接近。

摘  要：
Triticum aestivum spp yunnanense King originated from lower reaches of Lancang and Nu rivers in Yunnan Province.It has special traits such as hard chaff,which is difficult to shell,and fragile spike axes.This paper presents the study on drought resistance of seedlings and grown plants in Triticum aestivum spp yunnanense King.The results showed that there were significant variances in drought resistance of seedlings in different varieties.Of which,cultivar Youzhadi Guangtou was the strongest,following by Lancang Tieke,Yongde Tieke and Yunmai 42.Youzhadi Guangtou is a local cultivar of common wheat in Yunnan Province.Drought resistance of grown plant was stronger than that of seedling and no significant variance in different varieties.Of the all varieties tested, Yunxian Tieke was the best in drought resistance in grown plant and Youzhadi Guangtou was in second.Others were similar to Yunmai 42.
