Book Description
Wheat streak mosaic virus (WSMV) is a disease that causes significant yield losses in wheat (Triticum aestivum L.). Host resistance is the primary approach for control. KS06HW79 is a wheat line with WSMV resistance up to 21°C. To study the inheritance of resistance in KS06HW79, it was crossed with two WSMV-susceptible wheat genotypes, KS020638-M-5 and Brawl CL Plus. Parental lines, F1, F2, and check varieties were mechanically inoculated and evaluated for WSMV resistance at 21°C in growth chambers. The segregation pattern in two F2 populations fit a one-recessive-gene model (1 resistant : 3 susceptible) and a dominant-suppression-epistasis model (3 resistant : 13 susceptible). To determine which model was a better fit, WSMV resistance was evaluated for F2:3 families generated from resistant F2 plants in both crosses. Approximately two thirds of the F2:3 families in each cross showed segregation for WSMV resistance, suggesting that the dominant-suppression epistasis model better explained the WSMV resistance in KS06HW79. This model was also supported by two KS06HW79-derived doubled haploid populations, which had a segregation ratio of 1 resistant : 3 susceptible. Therefore, the WSMV resistance in KS06HW79 is likely controlled by two dominant genes, one of which is a suppressor.

Book Description
Wheat streak mosaic (WSM) caused by WSM virus (WSMV) is a serious disease of wheat which cannot be easily controlled using cultural practices or chemicals. Tolerance to WSMV exists in hexaploid spring wheat ('Triticum aestivum ' L) germplasm. BW155 is an advanced spring bread wheat line with tolerance to WSMV. Canada Western Red Spring (CWRS) wheat cultivar, AC Elsa is moderately susceptible, while AC Barrie and Laura are highly susceptible to WSMV infection. Wsm1, a gene for resistance to WSMV has been transferred into winter wheat from 'Agropyron intermedium'. The line 7166 is resistant to WSMV and carries the Wsm1 resistance gene. Both resistance and tolerance to WSMV contribute to the host's good performance. The overall objectives of this thesis were: (i) to determine the mode of inheritance of WSMV tolerance in BW155, and (ii) to combine BW155-derived tolerance and Wsm1 resistance derived from 7166.
