摘要
1987—1990年,以国内外芝麻种质资源3108份为材料,通过田间自然诱发和人工接种,进行抗茎点枯病鉴定。结果表明,无免疫品种,高抗品种32份,高耐品种112份,抗病品种885份,感病品种1756份,高感品种323份。江淮一年两熟夏芝麻区的抗源材料最多,其次为华北春芝麻区。国外资源中抗性材料所占比例较国内高。单秆型芝麻较分枝型芝麻的抗性强。白芝麻抗源材料最多,其次为黄芝麻、褐芝麻,而灰芝麻、黑芝麻抗性最差。
3108 varieties and lines of sesame(Sesamum indicum),which were coll ected from home and abroad,were identified for resistance to Macrophomina phaseolina during 1987-1990 under natural infection in field and artifi-cial inoculation in greenhouse No immune varieties were found.High resis tant,high tolerant,resistant,susceptible and high susceptible varieties had 32,112,885,1756 and 323 respectively Most of resistant varieties and lines distribute in the areas of Yangze River and Huanghe River,followed by those in north China.The proportion of resistant materials from abroad is higher than that from home.Single-stem type sesames had higher,resistance than multi-stem type.Among resistant germplasm,white seed sesames were most,yellow and brown seed sesames stood second,and resi seance of grey and black seed sesames were the worst.
