1997～ 1998年 ,对“八五”期间收集的芝麻种质资源初鉴获得的高抗茎点枯病和高抗枯萎病种质共85份及 4个育种单位提供的 8个新品系 ,在芝麻主产区三个生态试验点 (病圃 )进行了鉴定评价 ,均与当地优良品种进行比较 ,评价出抗性稳定、相对病情指数 <15 %的抗茎点枯病种质 34份、抗枯萎病种质 38份 ,其中兼抗两种病害的 2 7份 ,并明确了不同基因型抗源在不同生态系统中的抗性表现及利用价值 ,对抗、感品种酯酶同工酶分析表明 ,在A区检测出感病品种的相似性和抗、感品种间的带型差异 From 1997 to 1998, 85 germplasm with high resistance to blight and high resistance to blight collected from initial sesame germplasm collected during the “Eighth Five-Year Plan” period and 8 new lines provided by 4 breeding units Sesame main producing areas of the three ecological test sites (nurseries) were appraised and evaluated, were compared with the local elite varieties to evaluate the stability of the relative disease index <15% of the resistant stem spot blight germplasm 34, anti- Fusarium wilt germplasm 38, of which 27 were resistant to both diseases, and clear the resistance of different genotypes in different ecosystems of the resistance performance and value, antagonism, susceptible varieties of esterase isozymes showed that , In the A zone to detect the susceptible varieties of similarity and resistance, susceptible varieties of the band type differences
