受全国农业技术推广服务中心委托,2010年于河南安阳、河北保定、山东宁津,采用温室、病圃、重病田相结合的方法,对生产上大面积推广应用的、国审棉花品种的抗病性进行了监督测试。结果表明,所检测品种中,多数品种的抗枯萎病性和黄萎病性与审定时基本一致,少数品种抗性略有波动,只有极个别品种抗性变化较大。采用温室、病圃鉴定时,多数品种与审定时的抗性基本一致,抗性变化大的品种较少;而采用田间鉴定时,抗性发生变化的品种数量相对较多,可能与鉴定的环境条件有关。就目前检测结果来看,品种的抗性较为稳定。
Entrusted by the National Agricultural Technology Extension Service Center, in 2010 in Anyang, Henan, Baoding, Hebei, Shandong Ningjin, the use of greenhouse, nursery, a combination of serious disease on the production of a large area to promote the use of the national cotton varieties tested anti- The disease was supervised and tested. The results showed that most of the cultivars tested showed the same resistance to fusarium wilt and verticillium wilt. The resistance of a few cultivars fluctuated slightly, and the resistance of only a few cultivars varied greatly. When greenhouse and nursery garden were used for identification, the resistance of most of the cultivars was basically the same as that of the validation stage, and there were less varieties with large changes in resistance. However, the varieties with more resistance changed when the field was appraised, which may be related to the identified environment Conditions related. The current test results, the variety of resistance is more stable.
