摘　　要：用改良的G iemsa C-带技术对10个经辐射处理的带有黑麦某些性状的普通小麦品系进行鉴定。结果鉴定出1个小麦—黑麦易位系及2个小麦—黑麦异代换系,探索出冬季和夏季染色体分带的不同条件。因此,只要条件控制得当,C-分带不失为一种快速、精确而经济的鉴定外源染色体的方法。10 hybrids progeny which showed obvious rye characteristics were examinated by C-banding. 1 wheat-rye translocation line and 2 wheat-rye substitution lines were identified. Proper factors which influenced C-banding results were revised according to seasons （in winter and summer）, the results showed that C-banding was a rapid, economical and feasible method.
