چکیده

به‌منظور مکان‌یابی QTL‌های افزایشی و اپیستاتیک و اثر متقابل آنها با محیط برای صفات مرتبط با خصوصیات سنبله، 148لاین اینبرد نوترکیب گندم همراه با والدین YecoraRojo و No. 49 در دو ایستگاه تحقیقات کشاورزی میاندوآب و مهاباد در شرایط نرمال و تنش کم‌آبی انتهای فصل طی دو سال زراعی 1394 و 1393 مورد ارزیابی قرار گرفتند. نقشه پیوستگی مورد استفاده شامل 177 نشانگر ریز ماهواره و 51 نشانگر رتروترانسپوزون بود. برای تجزیه QTL‌ از نرم‌افزار QTL Network. 2 استفاده شد. در بررسی حاضر بیشترین مقدار وراثت‌پذیری عمومی (31/58 درصد) و خصوصی (15/29 درصد) برای تعداد سنبلچه در سنبله و کمترین مقدار وراثت‌پذیری عمومی (28/51 درصد) و خصوصی (64/25 درصد) برای طول سنبله در شرایط نرمال مشاهده شد. نتایج تجزیه QTL نشان داد در شرایط نرمال رطوبتی یک QTL (54/1 درصد=R2A)، یک اثر متقابل QTL در محیط (40/4 درصد=R2AE)، دو اثر اپیستازی QTL× QTL (4/0-44/0 درصد=R2AA) و 6 اثر متقابل QTL× QTL در محیط (24/8-7/9 درصد=R2AAE) مشاهده شد. در شرایط تنش کم-آبی، یک اپیستازی QTL× QTL (4 درصد=R2AA) و سه اثر QTL× QTL در محیط (98/6=R2AAE) مکان‌یابی شد، در مجموع دو شرایط نیز یکQTL (78/0 درصد =R2A)، یک اثر متقابل QTL با محیط (15/5 درصد=R2AE)، 10 اپیستازی QTL× QTL (02/0-9/7 درصد=R2AA) و 14 اثر QTL×QTL در محیط (86/0-92/8 درصد=R2AAE) معنی‌دار بودند. در این تحقیق تعداد QTL های شناسایی شده برای خصوصیات مرتبط با سنبله گندم بسیار کم بودند که می تواند به دلیل تعداد بالای QTL با اثرهای کم و همچنین اثرات محیطی باشد.

چکیده [English]

In order to mapping additive and epistatic QTL and their interaction with environment for traits related to spike characteristics using a RILs population of wheat, comprising 148 recombinant inbred lines derived from a cross between two winter wheat cultivars, ‘YecoraRojo’ and ‘No. 49’, was evaluated in two locations in Iran (Miandoab and Mahabad) during 2014-2016. A linkage map including 177 microsatellite and 51 retrotransposon markers was used in this study. Quantitative trait loci (QTL) were determined using QTL Network 2.0 software based on the CIM and mixed-linear method. In the present study, the highest broad (58.31%) and narrow-sense (29.15%) heritability was measured for spikelet number per spike and the lowest broad (51.28%) and narrow-sense (25.64%) heritability was detected for spike length. Results of QTL analysis showed that in normal condition, one QTL (R2A= 1.54%), one QTL×E (R2AE= 4.40%), 2 additive × additive epistatic effects (R2AA= 0.44- 0.4%) and 6 QTL × QTL×E interactions (R2AAE= 8.24-9.7%) were significant. In water deficit condition, 1 additive × additive interactions (R2AA= 4%) and 3 QTL × QTL × E interactions (R2AAE= 6.98%) were identified. In average of two conditions, two QTL (R2A= 0.78%), 1 QTL×E (R2AE= 5.15%), 10 additive × additive epistatic effects (R2AA= 0.02-7.9%) and 14 QTL × QTL × E interactions (R2AAE= 0.86-8.92%), were significant which can be due to the high number of QTLs with low effects and also environmental effects.
