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.
