Abstract

In order to mapping main and Epistatic QTL and their interaction with environment for biological yield 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 Cartographer 2. 5 and QTL Network 2. 0 software based on the CIM and mixed-linear method. In the present study, the estimated heritability for biological yield in normal, water deficit and average of two conditions were 26. 52, 26. 91 and 16. 09%. Also, the highest genetic gain for biological yield was observed in normal conditions. Results of QTL analysis showed. In normal condition, one QTL (R2 A= 2. 46), one QTL×E (R2 AE= 5. 46), 2 additive × additive epistatic effects (R2 AA= 3. 06) and 7 QTL × QTL×E interactions (R2 AAE= 14. 06) were significant. In water deficit condition, one QTL (R2 A= 8), 3 additive × additive interactions (R2 AA= 2. 04) and 3 QTL × QTL × E interactions (R2 AAE= 24. 74) were identified. In average of two conditions, two QTL (R2 A= 7), 3 QTL×E (R2 AE= 4. 66), 5 additive × additive epistatic effects (R2 AA= 4. 67) and 8 QTL × QTL × E interactions (R2 AAE= 24. 20), were significant. However, a little QTL was observed for biological yield, but in all three conditions, the role of the 7B chromosome in control of biological was significant and a stable QTL was located adjacent to the 'Cfa2174. 1-' Wms573 markers, which can be used in marker assisted selection for biologically selective.
