چکیده

پژوهش حاضر به منظور بررسی عملکرد، اجزای عملکرد و خصوصیات کمی و کیفی روغن استخراج شده از 19 لاین دابل‌هاپلوئید گیاه کاملینا در شرایط دیم کرمانشاه اجرا گردید. آزمایش بر پایه طرح بلوک‌های کامل تصادفی با 20 ژنوتیپ و سه تکرار در موسسه تحقیقات کشاورزی دیم سرارود کرمانشاه اجرا گردید. تیمارهای آزمایشی شامل رقم سهیل به عنوان شاهد و 19 لاین دابل‌هاپلوئید می‌باشند.نتایج نشان داد بیشترین عملکرد دانه (2/345 کیلوگرم در هکتار) هم در لاین 100DH بدست آمد که نسبت به رقم شاهد 5/43 درصد افزایش نشان داد. کمترین عملکرد دانه هم مربوط به لاین 105DH بود که نسبت به رقم شاهد 3/67 درصد کاهش نشان داد. علاوه بر این، بیشترین درصد و عملکرد روغن در لاین 100DH بدست آمد که نسبت به رقم سهیل 8/2 و 1/34 درصد افزایش نشان داد. آنالیز شیمیایی روغن کاملینا نشان داد که اسیدهای چرب غالب در روغن این گیاه شامل لینولنیک اسید (69/34-16/31 درصد)، لینولئیک اسید (93/18-74/16درصد)، اولئیک اسید (31/17-12/14درصد) و ایکوزنوئیک اسید (39/11-51/9) می‌باشد. بیشترین میزان اولئیک، لینولئیک و لینولنیک اسید در لاین 100DH مشاهده شد. علاوه بر این، بیشترین میزان ایکوزنوئیک اسید در لاین 10DH و پس از آن در لاین DH100 مشاهده شد. شایان ذکر است که میزان اسیدهای چرب غیراشباع اولئیک، لینولئیک، لینولنیک و ایکوزنوئیک نسبت به شاهد به ترتیب 9/10، 6/5، 4/6 و 7/8 درصد افزایش یافت.بطور کلی می‌توان نتیجه گرفت که لاین 100DH به دلیل بیشترین عملکرد و کیفیت روغن به عنوان لاین برتر جهت آزادسازی ارقام جدید از این گیاه دانه روغنی پیشنهاد می گردد.

چکیده [English]

The research was carried out in order to investigate the yield, yield components and quantitative and qualitative characteristics of the oil extracted from 19 double haploid lines of Camelina.

A field experiment was carried out as randomized complete block design with 20 treatments and three replications at the Serarud Rainfed Agricultural Research Institute of Kermanshah, Iran in 2021 growing season.
The results demonstrated that the highest seed yield of camelina was obtained in DH100 line, which showed an increase of 43.5% compared to the control variety. Also, the lowest seed yield was related to DH105 line, which showed a decrease of 67.3% compared to the control variety. In addition, the highest oil percentage and oil yield were obtained in DH100 line, Chemical analysis of camelina oil showed that the major fatty acids constituents in this plant's oil include linolenic acid, linoleic acid , oleic acid and eicosenoic acid . The highest amount of oleic, linoleic and linolenic acid was observed in DH100 line. In addition, the highest amount of eicosenoic acid belonged to the DH10 followed by DH100 line. It is worth mentioning that the amount of oleic, linoleic, linolenic and eicosenoic fatty acids increased by 10.9, 5.6, 6.4 and 8.7%, respectively, when compared with control variety.
it can be concluded that the DH100 line is recommended as the best line for releasing new cultivars of this oil-seed crop in rainfed conditions due to the highest oil quantity and quality in comparison with control variety and other double haploid lines.
