| چکیده | ||
| به منظور شناسایی لاینهای اوتایپ چغندرقند مقاوم به پوسیدگی ریشه ریزوکتونیایی، تعداد 51 لاین اوتایپ به همراه شاهد مقاوم و حساس در میکروپلاتهای ایستگاه اکباتان مرکز تحقیقات کشاورزی و منابع طبیعی همدان در سال 1400 ارزیابی شدند. برای آلودهسازی مصنوعی بوتهها، جدایه Rh133 از قارچ Rhizoctonia solani- AG2-2 بر روی بذر ذرت تکثیر و در کنار ریشههای 63 روزه چغندرقند قرار داده شد. در پایان فصل، ریشهها برداشت و بر اساس مقیاس یک تا نه نمرهدهی انجام و شاخص بیماری و شاخص برداشت بر مبنای آن برآورد شدند. مقایسه میانگین ژنوتیپها نشان داد اوتایپهای شماره 9 (FCOT 990084) و 19 (FCOT 990094) به ترتیب با مقادیر 55/3و76/3 واحد کمترین مقدار شاخص بیماری و با مقادیر 49/82 و 49/32 درصد بالاترین شاخص برداشت را به خود اختصاص دادند. بر اساس نتایج تجزیه خوشهای 48 ژنوتیپ چغندرقند تحت شرایط میکروپلات به پنچ گروه تقسیم شدند بین این گروهها از نظر تعداد بوته، تعداد ریشه، شاخص بیماری و شاخص برداشت اختلاف معنیداری وجود داشت. اوتایپهای شماره4 (FCOT 990079)،9 (FCOT 990084)، 19 (FCOT 990094)، 30 (FCOT 990105)، 47 (FCOT 990122) و رقم شاهد مقاوم 52 (Check1) در گروه شماره 5 قرار گرفتند که بالاترین مقدار شاخص برداشت و پایینترین شاخص بیماری را به خود اختصاص دادند. گروهبندی ژنوتیپهای اوتایپ بر اساس شاخص SIIG نشان داد ژنوتیپهای شماره 19 (FCOT 990094) و 9 (FCOT 990084)، 30 (FCOT 990105)، 4 (FCOT 990079)، 47 (FCOT 990122) به ترتیب با مقادیر0/854 و 0/824، 0/741، 0/708 و 0/701 نزدیکترین ژنوتیپها به ژنوتیپ های ایدهآل از لحاظ مقاومت به ریزوکتونیا بودند. | ||

| In order to distinguish O-type lines of sugar beet resistant to rhizoctonia root rot, 51 Otype lines along with resistant and susceptible controls were evaluated in the microplots at Ekbatan Station in Hamedan in 2021. To inoculate the seedlings to rhizoctonia, isolate Rh133 from rhizoctonia solani-AG2-2 fungus were propagated on corn seeds and placed next to root of 63-day-old plants. At the end of the season, roots were harvested and scored based on a scale of 1 to 9; thereafter, the disease index as well as harvest index were estimated. Results showed that Otypes 9 (FCOT 990084) and 19 (FCOT 990094) had the lowest disease index of 3.55 and 3.76, respectively, , and consequently the highest harvest index of 49.82 and 49.32%, respectively. Based on the results of cluster analysis, 48 sugar beet genotypes were divided into five groups under microplate condition. There was a significant difference among groups in terms of plant number, root number, disease index, and harvest index. Otypes 4 (FCOT 990079), 9 (FCOT 990084), 19 (FCOT 990094), 30 (FCOT 990105), and 47 (FCOT 990122) together with resistant control, cultivar 52 were placed in cluster 5 which had the highest harvest index and the lowest disease index. Grouping of Otype genotypes based on SIIG index showed that genotypes 19 (FCOT 990094), 9 (FCOT 990084), 30 (FCOT 990105), 4(FCOT 990079), and 47 (FCOT 990122) with values of 0.854, 0.824, 0.741, 0.708, and 0.701 were the closest genotypes to the ideal genotypes in terms of resistance to rhizoctonia. | ||
