摘要
选取84份经芜菁花叶病毒(TuMV)、霜霉病菌[Peronosporaparasitica(Pers.)Fr.]、黑斑病菌[Alternariabrasicae(Berk)Sac.]单抗鉴定后筛选出的自交系,于1992~1993年对其进行上述3种病害苗期人工诱发接种多抗性联合鉴定,获得21份三抗材料。经鉴定,确认为三抗抗源材料。探讨了多抗性联合鉴定的技术与方法。
The triple resistance of Brassica campestris ssp. chinensis Makino to TuMV, Peronospora parasitica (Pers.) Fr. and Alternaria brassicae (Berk) Sacc. was identified by artificial seedling inoculation in the autumn of 1993. A total of 84 selfed lines derived from single resistance tests was used as experimental materials. Twenty one lines were identified as triple resistant sources, from which 6 lines were sent to the National Key Research Program of Chinese Cabbage for unified disease resistance test. The triple resistance of these 6 lines was confirmed by the national test.
