摘　　要：通过 1998～ 1999、1999～ 2 0 0 0两年度对 3个不同类型的 4个冬小麦品种 (系 )根系进行研究表明 ,不同类型冬小麦品种的根系生长差异较大。大穗型 93中 6的根长密度扬花期高于其它 3个品种 ;中间型周麦 13的根长密度在拔节孕穗期较高 ,后期则很低 ,根系衰退较快 ;多穗型中育 6号、98中 18的根长密度在生长中后期较平稳。Root growth traits in the whole stage of different types of wheat cultivar showed quite difference. The root system of 93 Zhong6, which is a dwarf and big-ear variety, reached its higher growth in the anthesis period. The root density of Zhoumai13, middle type variety, had a higher value in the elongation stage and then fast aging, led to low yield. Root density of Zhongyu6 and 98 Zhong18 with a high yield and multiple ears was a stable in middle-late stage. In 1998～2000 years we studies 4 different cultivars of winter wheat. The retults was showed.
