不同地区啤酒大麦品种农艺性状鉴定与分类研究

为筛选可用于云南啤酒大麦改良的优良种质材料,对107份不同来源啤酒大麦品种的农艺性状进行鉴定与分类研究.结果表明,云南啤酒大麦的主要特点是成熟期长,分蘖较强,植株高,旗叶面积大,穗长、穗粒数、穗粒重、千粒重、秸秆干重中等,穗草比较高;国外引进品种株型中等紧凑,叶片细长,穗粒重和千粒重较大,穗草比适中.从中筛选出19份性状优良的材料.通过聚类分析,可将供试材料划分成4个性状不同的类群,各类群的农艺性状差异明显,有利于育种目标材料的选择.

Analysis of the Agronomic Characteristics and Classification of Malting Barley from Different Regions

In order to select good germplasm for improvement of Yunnan malting barley, agronomic characteristics of 107 accession of malting barley from different ecological regions were evaluated and classified. The results showed that the malting barley cultivars from Yunnan have the common characters of long maturity, strong tillering, high plant, wide flag leaves, middle spike length, grain number per spike, grain weight per spike, 1000-grain weight, and dry panicle grain/item. The cultivars from abroad have middle height and compact plant type, long and narrow leaves, high single panicle grain weight, 1000-grain weight, middle panicle grain/item. Nineteen cultivars with good morphological characteristics were selected for possible parents to improve productivity of barley in Yunnan. Through a cluster analysis, the material could be divided into 4 groups with different characteristics in which differences morphological character was obvious. It would be advantageous to the choice of breeding material.
