[ 1 ] - پراکنش جدایه‌های سینوریزوبیومی تولید کننده ملانین همزیست با یونجه در مناطق غرب و شمال غربی ایران
به منظور تعیین پراکنش سینوریزوبیومهای تولید کننده ملانین همزیست با یونجه در نواحی غرب و شمال غربی ایران، تعداد 982 جدایه از سینوریزوبیومهای همزیست با دو جمعیت یونجه داخلی (همدانی و نیک شهری) و یک جمعیت خارجی (کودی)، در هشت خاک جمع آوری شده از استانهای کردستان، کرمانشاه، آذربایجان شرقی و کردستان، انتخاب شدند که از بین آنها تعداد 237 جدایه (1/24%) توانایی تولید ملانین را داشتند. نتایج نشان داد ک...
[ 2 ] - ارزیابی تحمل به خشکی به‌منظور افزایش بهره‌وری مصرف آب در بزرک
انتخاب رقم پرمحصول و مقاوم به تنش با بیشترین کارایی و بهره‌وری مصرف آب، از مهم‌ترین ابزارهای مدیریت آب در مزرعه در مناطق خشک و نیمه‌خشک است. این پژوهش به‌منظور شناسایی فامیل‌های مقاوم و متحمل به تنش خشکی با بیشترین بهره‌وری مصرف آب در بین 119 فامیل F2:3 حاصل تلاقی یک لاین داخلی (KO37) با یک لاین کانادایی (SP1066) در دو محیط تنش و عدم تنش رطوبتی انجام گرفت. نتایج مقایسۀ میانگین صفات نشان داد که...
[ 3 ] - Genetic variation and heritability for germination, seed vigour and field emergence in brown and yellow-seeded genotypes of flax
Genetic improvement of seed vigour and emergence of yellow-seeded flax (Linum usitatissimum L.) is important to have a good stand establishment, since they are negatively affected by yellow seed colour. This study was conducted to investigate genetic variation, broad-sense heritability and expected genetic response to selection for germination, seed vigour and field emergence. Sixteen genotypes...
[ 4 ] - Morpho-phenology and chromosome number of Iranian Bromus danthoniae Trin. genotypes
ABSTRACT- Bromus danthoniae Trin. is an annual grass species which grows mainly on dry grassy rocky mountain slopes and grassy steppe, and is grazed by many herbivores and recognized as a useful pasture plant. The chromosome number, morphological and anatomical traits of 82 genotypes of B. danthoniae belonging to three sub-taxa were investigated. Twenty-seven quantitative and 20 qualitative mor...
[ 5 ] - تاثیر تنش شوری بر فعالیت آنزیم‌های آنتی اکسیدان و محتوای کلروفیل برگ در ژنوتیپ-های حساس و متحمل به شوری گلرنگ (Carthamus tinctorius L.)
The effect of salinity stress on the antioxidant activity of catalase and peroxidase enzymes, relative water content, chlorophyll and carotenoid contents of eight safflower (Carthamus tinctorius L.) genotypes differing in salinity tolerance (4 salt tolerant and 4 salt sensitive) were evaluated. This study was conducted using a split plot design arranged as a completely randomized design replic...
[ 6 ] - Genetic Analysis of Androgenetic Traits in Wheat (Triticum aestivum L.)
The objective of this study was to estimate genetic parameters and to investigate the type of gene action in controlling androgenesis in wheat. Two wheat cultivars of Grebe and Houtman were reciprocally crossed with two synthetic genotypes of Do1 and Pol and then a complete set of the parents, F1, reciprocal F1 (RF1), F2 and back-cross generations (BC1 and BC2) of each cross were used for anthe...
[ 7 ] - مطالعه اجزای عملکرد و صفات زراعی در برخی از فامیل‌هایF3 بزرک (Linum usitatissimum L.)
In order to study seed yield components and agronomic traits in some F3 families of flax (Linum usitatissimum L.), this experiment was conducted in 2014 at the Research Farm of Isfahan University of Technology, Isfahan, Iran. In this experiment, 50 families of F3 generation derived from different crosses were evaluated in a randomized complete block design with two replications. The results sho...
[ 8 ] - Efficiency of Indirect Selection to Improve Yield and Drought Tolerance in Populations Derived from Inter-Specific Hybridization of Soft Flower
The use of appropriate selection methods are important to increase yield in breeding programs. Utilization of selection indices is one of the most effective method for selection of superior genotypes to improve the complex traits such as seed yield. In order to evaluate the efficiency of different selection methods, 63 families of two F3 populations derived from inter-specific hybridization of ...
[ 9 ] - Investigation of Water Stress Tolerance in Some Sesame (Sesamum indicum L.) Genotypes using Tolerance and Sensitivity Indices
This experiment was conducted at the Research Farm of Isfahan University of Technology, Najafabad, Iran in 2014 and 2015 to evaluate drought tolerance indices of some sesame (Sesamum indicum L.) genotypes. In this study, 21 sesame genotypes isolated from different local populations along with seven exotic cultivars were evaluated at two irrigation regimes, using a randomized complete block desi...
[ 10 ] - ارزیابی تحمل خشکی هیبرید بین‌گونه‌ای و چند ژنوتیپ گلرنگ با استفاده از شاخص‌های مقاومت به خشکی
مطالعه‌ای با هدف ارزیابی تحمل خشکی ژنوتیپ‌های حاصل از تلاقی بین‌گونه‌ای در مقایسه با ارقام تجاری گلرنگ در مزرعه تحقیقاتی دانشگاه صنعتی اصفهان واقع در لورک نجف‌آباد به‌صورت طرح بلوک کامل تصادفی در سه تکرار و در دو سطح رطوبتی به‌عنوان محیط (نرمال و تنش 90% تخلیه رطوبتی) انجام شد. 5 ژنوتیپ گلرنگ شامل A82 (هیبرید بین‌گونه‌ای (گلرنگ زراعی Carthamus tinctorius L. با گونه وحشی C. oxyacanthus) گلرنگ در...
[ 11 ] - Evaluation of Drought Tolerance in Some Safflower (Carthamus tinctorius L.) Genotypes
In order to evaluate drought tolerance of some safflower genotypes, an experiment was conducted at the Research Farm of Isfahan University of Technology in 2016 and 2017. In this study, 18 safflower genotypes selected from different local populations along with 2 exotic cultivars and one local population (21 genotypes) were separately evaluated at two normal (non-stress) and water deficit (s...
[ 12 ] - Evaluation of Agronomic Traits and Drought Tolerance of Safflower Lines Derived from Three Inter-Specific Crosses
Due to genetic erosion over evolution events, the genetic diversity of domesticated safflower species for drought tolerance is limited. Wild species has been considered as useful genetic resources for improvement of abiotic stress tolerance. In this study, a cultivated species (C. tinctorius) was crossed by two wild species (C. palaestinus and C. oxyacanthus) and the genotypes were purified unt...
[ 13 ] - Evaluation of Water Deficit Tolerance Indices in New Hybrids of Maize (Zea mays L.) with SIMMYT Origin
Regarding the insufficient water resources, developing of cultivars with high tolerance to water deficit can be very effective to optimize water consumption. To identify maize hybrids with higher tolerance to water deficit, 52 single cross hybrids were field evaluated according to a randomized complete block design with three replications in each irrigation regime. The hybrids were produced thr...
[ 14 ] - Response of Emmer and Durum Wheats to Different Levels of Nitrogen Fertilizer
Emmer tetraploid hulled wheats are considered as the ancestor of modern wheat and have considerable potential for durum wheat improvement, especially in terms of grain protein content. To investigate the response of emmer and durum wheats to different levels of nitrogen fertilizer, eight durum and four emmer genotypes were evaluated in the field during 2017 cropping season. The experiment was c...
