摘要
以8份白菜自交系材料为试材,分别利用网室鉴定和离体鉴定两种方法进行抗虫性鉴定。结果表明,两种鉴定方法的结果基本一致,材料间对小菜蛾抗性均表现极显著差异;在网室鉴定和离体鉴定中,599-3-7均表现高抗,519-3-3均表现中抗,而114-4-4和116-4-4都表现高感,部分材料的表现稍有差异;两种鉴定方法的相关系数为0.96,达到极显著水平;离体鉴定和网室鉴定相结合,能准确、全面地研究植物对小菜蛾的抗性及抗虫机理。
Eight Chinese cabbage inbred lines were selected to evaluate their resistance to diamondback moth（DBM） by using two methods ：in vitro and under net conditions. The results showed that the resistance to DBM differed very significantly among the 8 lines, and there were no obvious difference between the two methods. Line 599 - 3 - 7 exhibited the highest resistance ,519 - 3 - 3 showed middle resistance, 114 - 4 - 4 and 116 - 4 - 4 were the most susceptible lines. The correlation coefficient of the two methods was 0.96. Combinating the two methods to study resistance to diamondback moth and mechanisms completely and accurately.
