چکیده

به منظور ارزیابی آلودگی ارقام و لاین های مختلف چغندرقند به بید چغندرقند (Scrobipalpa ocellatella)در سال 1392 آزمایشی با 24 رقم و لاین چغندر قند، در شرایط آلودگی طبیعی در مزرعه در کرج انجام و با توجه به چند نسلی بودن این آفت، درصد آلودگی تیمارها در طول فصل زراعی (هشت مرحله، ده روز یکبار) مورد ارزیابی قرار گرفت. بعد از آخرین مرحله نمونه برداری در تاریخ 25 شهریور، تیمارها با استفاده از روش محاسبه فواصل انحراف معیار از میانگین در چهارگروه با آلودگی کم، آلودگی متوسط، آلودگی زیاد و آلودگی بسیار زیاد گروه بندی شدند. ارقام تجاریSBSI 016، مراک و7K43 به عنوان ارقام با آلودگی کم و ارقام رزیر، دوروتی و لاین پدری جلگه در گروه ارقام با آلودگی بسیار زیاد دسته بندی شدند. بر اساس مشاهدات مزرعه ای اولین علایم آلودگی به آفت در زمان 6 تا 8 برگی بوته ها و در اوایل تیر ماه مشاهده شد ولی درصد آلودگی تا اواخر تیر ماه بسیار کم (کمتر از 1/37-0/34% ) و در شهریور به بیش از 50% رسید. با توجه به نتایج این تحقیق پیشنهاد میشود جهت برنامه های اصلاحی چغندرقند، از پتانسیل مقاومت موجود در بین ارقام برای کنترل خسارت این آفت استفاده شود.

چکیده [English]

In order to evaluate the infection rate of different sugar beet lines and cultivars to S. ocellatella, 24 sugar beet lines and cultivars were evaluated under natural infection in the field in Karaj, in 2013.Considering the presence of several generations of the pest, the infection rate treatments were evaluated during the growing season (eight stages, every 10days). After last sampling on 16 September, treatments were classified to four groups (low, medium, high, and very high infection) based on standard deviation distance from mean. The commercial varieties Paya, Marak, and 7K43 were placed in low infection group, whereas Rosire, Dorothea and the male line of Jolgeh in the very high infection group. Based on field observations, the first symptoms of the pest infection were emerged at 6-8-leaf stage early July; however, the infection percentage was low early July (less than 0.34-1.37%) and increased to more than 50% in August. In general, it is recommended that in sugar beet breeding programs, the resistance potential of the cultivars be used for damage control.
