چکیده
انواع مختلف هیبریدهای وارداتی و تولیدی داخلی کرم ابریشم و در شرایط مختلف آب‌وهوایی استانهایمختلف کشور پرورش داده میشوند. هدف از این پژوهش، مقایسه عملکردهیبریدهای مورداستفاده کرم ابریشمدر دو منطقه با شرایط آب‌وهوایی متفاوت یعنی شفت در استان گیلان و تربت‌حیدریه در استان خراسان رضوی بود. برای انجام این پژوهش چهار هیبرید ایرانی و 14 هیبرید وارداتی چین در قالب طرح بلوکهای کامل تصادفی استفاده شد. برای صفات موردبررسی تعداد پیله در لیتر، میانگین وزن یک پیله، درصد قشر یک پیله و وزن پیله تولیدی از یک جعبه، اختلاف معنی‌داری بین هیبریدها و هم‌چنین بین دو منطقه شفت و تربت‌حیدریه وجود داشت (0/01>P). نتایج مطالعه حاضر نشان داد که عملکرد هیبریدهای کرم ابریشم بدون درنظرگرفتن منشأآن‌هابیش‌تر تحت تأثیر محیط پرورشی قرار دارند،هم‌چنین بین هیبریدها در اقلیم‌هایموردمطالعه تفاوت وجود دارد. لذا انتخاب مناسب‌ترین هیبریدها برای اقلیم‌های مختلف ایران ضروری است.

چکیده [English]
Different types of imported and domesticatedhybrids of silkworm are rearing in different climatic conditions in Iran. The purpose of this study was to compare the performance of silkworm hybrids used in two climatic regions ofIran, namely Shaft in Guilan province and Torbat Heydariyeh in Khorasan Razavi province.For this study, four Iranian hybrids and 14 Chinese imported hybrids were used in a completely randomized block design. For the studied traitsnumber of cocoons per liter, average weight of a cocoon, and weight of cocoon produced from a box, there was a significant difference(P<0.01) between the hybrids as well as the regions. The results of the present study showed that the performance of silkworm hybrids, regardless of their origin, is more affected by the rearing environment and there is a difference between hybrids in the studied climates. Therefore, selecting the most suitable hybrids for different climates of Iran seem to be essential.
