当前我国大白菜育种受生态类型、消费习惯及育种材料等诸多因素限制，育成品种的抗病性相对单一。针对大白菜多种病害复合抗性较差的问题，利用 TuMV抗源材料BP006（8407）、高抗黑腐病资源材料秦白－2进行了多种大白菜病害抗性基因的聚合育种，选育出抗多种病害、品质优良的不同熟性、不同类型高代稳定自交系和自交不亲和系。多抗4号是以自交不亲和系2005 M－3与自交系04－5杂交选育而成的大白菜新品种。该品种高产，抗逆性强，高抗病毒病、霜霉病和黑腐病，品质佳，口感好，在河北省中南部7月24日～8月20日均可播种。

Chinese cabbage varieties were bred in current with relatively single disease resistance that was limited by many factors, such as ecology type, consumption custom and breeding materials etc.According to the problem of several diseases poor composite resistance on Chinese cabbage, inbred line BP006 ( 8407 ) with TuMV high resistance, Qinbai-2 with high resistance to black rot were used to have new breeding materials with composite high disease resistance.High-generation inbred lines with high quality, different varieties of ripe and high serval diseases resistance were bred.Duokang No.4 ( F1 ) was the new variety bred by cross 2005M-3 and 04-5.It has high quality, high disease resistance to virus disease, cowny mildew and black rot, high stress resistance.It can be planted from July 24th to August 20th in central and southern of Hebei Province.
