对从荷兰引进的番茄新品种特宝1号进行番茄青枯病(R a lston ia solanacearum)抗性测定试验,结果表明,该品种表现出较好的抗性。苗期人工接种后,30d才出现症状,比抗病品种抗青1号的发病时间推迟15d,发病率低且病害发展缓慢,校正发病率差异达到极显著水平。该品种还具有早熟、生长势强、不易早衰、丰产性好和特别耐贮运等特点。

The experiment of determinating the resistance to Ralstonia solanacearurn of new tomato variety Tebao no. 1 introduced from Holland was carried out.
