| چکیده | ||
| نماتد سیستی (Heterodera schachtii Schmidt) یکی از عوامل محدود کننده رشد چغندرقند (Betavulgaris L.) میباشد. با توجه به اهمیت و گستردگی این نماتد در جهان و به منظور جلوگیری از کاهش قابل توجه محصول، مناسبترین روش مدیریت آن، استفاده از ارقام مقاوم میباشد. در این تحقیق حساسیت 70 ژنوتیپ چغندرقنددر برابر نماتد سیستی به صورت طرح کامل تصادفی در سه تکرار در سطح گلخانه و طرح بلوکهای کامل تصادفی در سه تکرار در سطح مزرعه در اصفهان بررسی شدند. تجزیه آماری دادههای حاصل از آزمایشات گلخانهای و مزرعهای با نرم افزار SASو گروهبندی خوشهای آنها توسط نرمافزار SPSSنشان داد که ژنوتیپهای 53 (SB-2)، 69 (NE 0911)، 16 (SB32-HSF-5) کمترین تعداد سیست و ژنوتیپهای 16 (SB32-HSF-5)و 5 (SB31-HSF-2)کمترین میزان تخم و لارو و فاکتور تولیدمثل را دارا بودند. این دو لاین 16 (SB32-HSF-5) و5 (SB31-HSF-2)، به عنوان مقاومترین ژنوتیپها شناخته شده و در یک خوشه قرار گرفتند. به این ترتیب، میتوان از ژنوتیپهای فوق الذکر در مقاومت به نماتدسیستی چغندرقندو نیز برنامههای اصلاحی استفاده نمود. | ||

| چکیده [English] | ||
| Sugar beet cyst nematode (Heterodera schachtii Schmidt), is one of the limiting factors of sugar beet growth. Considering the importance and magnitude of this nematode distribution in Iran and also to decrease its destructive damage, use of resistant varieties is recommended. Prerequisite for resistant variety development is resistant genotype availability. In this study, resistance of 70 sugar beet genotypes to sugar beet cyst nematode was evaluated in a completely randomized design with three replications in the greenhouse and in a randomized complete block design with three replications in the field condition in Isfahan, Iran. Data analysis was performed using SAS software and cluster analysis was done by SPSS software. Results showed that genotypes 53 (SB-2), 69 (NE 0911), and 16 (SB32-HSF-5) had the minimum number of cysts, and genotypes16 (SB32-HSF-5) and 5 (SB31-HSF-2) had the lowest rates of eggs, larva and reproductive factor, respectively. The genotypes 16 (SB32-HSF-5) and 5 (SB31-HSF-2) were identified as the most resistant genotypes and were placed in the same cluster. Therefore, these genotypes can be used in breeding programs for resistant variety development. | ||
