摘要： 为了探明胶东地区适宜的小麦品种类型与育种方向，通过11个不同的小麦基因型，采用t测验法对2种穗型小麦品种的若干性状差异进行了研究。结果表明：大穗型品种的单茎草重、茎质系数、穗粒数、千粒重、穗粒重比多穗型品种高0.958 g、0.011 g/cm、5.354粒、5.460 g、0.504 g，均达到极显著水平；多穗型品种的单位面积穗数、经济系数和群体产量比大穗型品种高289.847万/hm2、0.027、859 kg/hm2，均达到极显著水平。在胶东地区生态条件下，应以分蘖力中等、茎秆粗壮、成穗率高、产量三因素协调的多穗型品种为主攻方向。

Abstract: In order to ascertain the suitable wheat cultivars and the breeding direction in eastern Shandong, several characteristic differences of two spike-type cultivars of wheat were studied by t-test using 11 wheat genotypes. The results showed that grass weight per stem, weight length per stem, grains per spike, thousand grain weight, spike weight per stem of large-spike cultivar were 0.958 g, 0.011 g/cm, 5.354 grain, 5.460 g, 0.504 g higher than that of multi-spike cultivar, which all reached extremely significant level, spikes per hectare, harvest index and population yield of multi-spike cultivar were 2.898 million/hm2, 0.027, 859 kg/hm2 higher than that of large-spike cultivar, which all reached extremely significant level. Thus under the ecological conditions in eastern Shandong, the main direction of breeding should focus on multi-spike cultivars with midium tillering ability, thick stem, high spike rate, and coordinated yield components.
