作者从1983年起与国际白粉病圃(IWWPMN)合作,四年来共引种鉴定972份新品种(系)。这些材料的亲本多具近缘种属血统,而且是包含多个抗病基因及多个抗源品种的复交产物。在开展抗白粉病筛选的基础上,又进行了抗赤霉病鉴定,并在国内开展多点、多抗、异地鉴定,有些材料还进行了抗性的遗传分析。本文综合多年鉴定结果,介绍7个多抗新抗源,推荐利用。
Since 1983, the author has cooperated with International Powderworm Nurseries (IWWPMN) for a total of 972 new varieties (lines). The parents of these materials are mostly related species and their origin, and is a complex product that contains multiple resistance genes and multiple resistant varieties. On the basis of carrying out screening against powdery mildew, we also carried out the identification of scab resistance and carried out multi-point, multi-resistance and off-site identification in China, and some of the materials were also subjected to genetic analysis of resistance. Based on the results of many years of accreditation, this article introduces 7 new anti-multi-resistance sources and is recommended for use.
