摘　　要：以豫麦49、豫麦18为对照,对豫麦66及其优系和矮早系的花器构造、散粉特性和穗部特征进行了研究。结果表明:与对照相比,豫麦66各系的花药大,穗子较长,开颖角度较大,开花持续期较长,而且穗粒数、穗花数、外露花药数、中部穗粒数都较多,是理想的杂交小麦父本材料。The inflorescence organization, the blooming habits and the spike characteristics of Yumai No.66 were studied in this paper. The results showed that Yumai No.66 had bigger anther and patulous angle of glume, longer flowering period and more kernels per spike, flowers per spike, extruded anthers and kernels of the middle spikelet than Yumai No.49 and Yumai No.18, so it is a good male parent in the study of hybrid wheat.
