“…Higher temperatures can destabilize wheat cultivars and affect wheat resistance to Hf larval attack (Brahmi et al, 2021;Chen et al, 2014;Nemacheck et al, 2023;.

Deploying resistant wheat cultivars is the most economical and environment‐friendly strategy to manage the devastating effects of the dipteran pest, Hessian fly (Hf; Mayetiola destructor). Currently, 37 Hf resistance genes have been identified to combat the 18 Hf genotypes documented so far. However, the Hf populations adapt rapidly to overcome the newly deployed resistance genes within a few years of release resulting in development of virulent Hf biotypes and breakdown of plant resistance. Identification of new and novel sources of resistance offers breeders additional resources that can be included in the breeding programmes to develop elite Hf‐resistant cultivars. In the current study, we screened 374 wheat (tetraploid and hexaploid) accessions originating from different regions of the United States and identified three tetraploid (Triticum turgidum) pasta wheat lines, one originating from North Dakota (PI 639869) and two from Minnesota (PI 352398 and CItr 15710) exhibiting ≥95% resistance to Hf biotype L at 20°C. Further, the wheat cultivar PI 352398 showed 100% resistance to six additional Hf genotypes including biotypes B, C, D, O, GP and vH13. The lines PI 639869 and CItr 15710 also showed >70% resistance with most biotypes, except against biotype GP with the former and biotype B with the latter. Interestingly, a few plants from these two cultivars exhibited putative tolerance to these biotypes where the plants showed normal growth but harboured white, live larvae and showed cell permeability that was intermediate in levels between Hf‐infested resistant and susceptible wheat. Additionally, since the increase in environmental temperatures to 25–30°C also negatively impacts Hf resistance, the three T. turgidum (PI 639869, PI 352398 and CItr 15710) cultivars were evaluated for Hf resistance at 30°C. None of the wheat cultivars were resistant to Hf biotype L at 30°C indicating a temperature‐dependent breakdown of resistance and are therefore not suitable for geographical regions with higher environmental temperatures. Taken together, these three wheat lines represent additional sources of Hf resistance that can be leveraged by breeders for developing durable elite lines.

“…However, it is unexpected that 27 purified accessions decreased resistance scores or became completely susceptible ( Figure 3E , Supplementary Table S1 ). Hessian fly resistance in wheat is also greatly impacted by environmental factors, especially temperatures ( Liu et al., 2007 ; Brahmi et al., 2021 ). Escape of HF infestation in the initial screening and variation in screening environments might be partially responsible for the inversion from resistant to susceptible after seed purification.…”

Hessian fly (HF), Mayetiola destructor, is a major insect pest that causes severe losses in grain yield and quality of wheat (Triticum aestivum). Growing resistant cultivars is the most cost-effective approach to minimize wheat yield losses caused by HF. In this study, 2,496 wheat accessions were screened for resistance to the HF biotype ‘Great Plains’ (GP) in the greenhouse experiments. To purify seeds from heterogeneous resistant accessions, we recovered single resistant plants from 331 accessions that had at least one resistant plant after HF infestation of a global collection of 1,595 accessions and confirmed 27 accessions with high resistance (HR), and 91 accessions with moderate resistance (MR) to the GP biotype using purified seeds. Screening of 203 U.S. winter wheat accessions in three experiments identified 63 HR and 28 MR accessions; and screening of three additional Asian panels identified 4 HR and 25 MR accessions. Together, this study identified 96 HR accessions and 144 MR accessions. Analysis of the geographic distribution of these HR and MR accessions revealed that these countries with HF as a major wheat pest usually showed higher frequencies of resistant accessions, with the highest frequency of HR (81.3%) and MR (30.6%) accessions identified from the U.S. In addition, phenotyping of 39 wheat accessions that carry known HF resistance genes showed that all the accessions except H1H2 remain effective against GP biotype. Some of these newly identified resistant accessions may contain new HF resistance genes and can be valuable sources for developing HF resistant wheat cultivars.

“…Besides influencing crop growth and development, elevated temperature also (i) favors herbivore population growth and insect pest survival (Hough et al., 2017; Tonnang et al., 2022) and (ii) weakens host plant defense and immunity against insects, thereby increasing disease incidences resulting in significant reduction in crop yield and quality (Grace et al., 2019; Khan et al., 2021; Porfirio et al., 2018; Zhu et al., 2010). Hence, it is vital to regularly evaluate the effects of increased temperatures on the expression of HF resistance in newly identified sources of wheat resistance to ensure selection of stable genes and implementation of appropriate deployment strategies (Brahmi et al., 2021). We evaluated and compared the expression of resistance at 20 and 30°C in the 12 wheat lines that were resistant to Biotype L. As the screening in the greenhouse was done during the months of October–November when the temperatures are cooler in the greenhouse, it is possible that the lower temperatures resulted in increased resistance in some of the wheat accessions, compared to 20°C in a growth chamber.…”

Identification of new sources of Hessian fly resistance in tetraploid wheat

et al. 2023

Hessian fly (HF) (Mayetiola destructor Say) is an obligate destructive pest of wheat (Triticum aestivum L.) causing severe economic losses worldwide. Deployment of resistant wheat cultivars harboring HF resistance (H) genes is still the most effective and economical method to manage this insect pest. However, extensive use of H genes can impose selection pressure on HF populations, leading to the development of virulent biotypes that can breakdown plant resistance. Further, increase in environmental temperatures to 25–30°C during the wheat‐growing season can also negatively impact HF resistance, thereby necessitating the identification of new and novel sources of HF resistance and evaluate them for temperature sensitivity. In the current study, we evaluated the phenotypic response of 254 Triticum turgidum (L.) wheat accessions of African origin to Biotype L HF infestation. Of these, 10 accessions exhibited >70% resistance to Biotype L HF infestation. These 10 resistant accessions also showed >70% resistance when screened with vH13 HF biotype. Additionally, these HF resistant lines were evaluated for expression of resistance at a higher temperature of 30°C, and three tetraploid wheat accessions that maintained 100% resistance to Biotype L HF at the increased temperature were identified. These newly identified HF resistant lines offer valuable tools to breeders and farmers that can be used in breeding programs to develop cultivars for durable resistance to HF and efficient crop management.
