چکیده مقاله :
در این تحقیق تجزیه ارتباطی 105 ژنوتیپ گندم نان (Triticum aestivum L.) با استفاده از 12 آغازگر SSR مورد ارزیابی قرار گرفت. بدین منظور، بذور گندم در قالب طرح بلوک های کامل تصادفی در سه تکرار و در دو شرایط نرمال (mM NaCl 10) و شور (mM NaCl 120) در گلدان ها کشت شدند و فعالیت آنزیم های کاتالاز، آسکوربات پراکسیداز و محتوای پروتئین کل مورد سنجش قرار گرفت. نتایج تجزیه واریانس مرکب داده های فیزیولوژیک، نشان داد که فعالیت آنزیم های کاتالاز، آسکوربات پراکسیداز و محتوای پروتئین کل در ارقام مورد مطالعه گندم نان، تفاوت معنی داری را داشتند. نتایج تجزیه رگرسیون چند متغیره نشان داد که نشانگرهای gwm67b - gwm282d تحت شرایط شوری، نسبت به سایر نشانگرهای مورد مطالعه ، پیوستگی بیشتری با فعالیت کاتالاز در گونه های مورد مطالعه داشته اند. همچنین جدول مربوطه، مارکرهای gwm291a- wmc73a- barc124a را بعنوان موثرترین نشانگرها در پیوستگی با آنزیم APXمعرفی نمود. تجزیه ساختار جمعیت و بارپلات بدست آمده از آن نیز نشان داد که شاخص K و متوسط لگاریتم لایک لی هود، بیشترین مقدار را در2 K= (57.38) دااشته اند، بنابراین به احتمال قوی جمعیت مورد استفاده دارای 2 زیر جمعیت بودند. تجزیه Tassel مربوط به نشانگرهای SSR تحت شرایط آبیاری طبیعی و آبیاری با آب شور نشان داد که 54 مکان مرتبط با صفات مورد مطالعه در شرایط شاهد و 61 مکان در شرایط شوری بر اساس مدل خطی عمومی (GLM) و همچنین 35 مکان مرتبط در شرایط شاهد و 20 مکان در شرایط شوری بر اساس مدل خطی مختلط (MLM) به دست آمد.
Association analysis of 105 bread wheat (Triticum aestivum L.) genotypes was carried out using 12 SSR markers. For this purpose, wheat seeds were planted in pots in a randomized complete block design with three replications under normal (10 mM NaCl) and saline (120 mM NaCl) conditions and the activity of catalase (CAT), ascorbate peroxidase (APX), and total protein contents were measured. The results of combined analysis of variance showed that the activity of catalase, ascorbate peroxidase, and total protein contents were significantly different in the bread wheat cultivars under study. The results of multiple regression analysis showed that gwm67b and gwm282d markers under salinity conditions were more correlated with catalase activity in the studied species. Also, gwm291a, wmc73a, and barc124a markers were the most effective markers in association with APX enzyme. Analysis of the population structure and the resulting plot showed that the K Index and the Average Likelihood Logarithm had the highest value at K =2 (57.38), thus the population under study has most probably 2 subpopulations. Tassel analysis of SSR markers under normal irrigation and salinity irrigation conditions obtained 54 loci related to the traits under study in control condition and 61 loci in salinity condition based on the general linear model (GLM) and also 35 related loci in control condition and 20 loci in salinity condition based on the mixed linear model (MLM)
