“…Nine resistant genotypes were grouped in one cluster, while the remaining eleven genotypes were gathered in another group. Additionally, Mabrouk et al (2022) tested yellow rust in different wheat genotypes. They employed the disease parameters i.e., FRS and AUDPC to differentiate the resistant and susceptible genotypes.Their results displayed substantial differences among the evaluated genotypes in FRS and AUDPC scores.…”

Yellow rust and heat stress adversatively impact the growth and production of bread wheat in particular under rising adverse environmental conditions. Stability of grain yield is a pivotal purpose of plant breeders to improve wheat production and ensure global food security especially under abrupt climate change. The objective of this study was to assess the performance and stability of diverse bread wheat genotypes for yellow rust resistance, heat stress, and yield traits. The studied genotypes were evaluated in two different locations under two sowing dates (timely and late sowing) during two growing seasons. The obtained results displayed significant differences among the tested locations, sowing dates, and genotypes for most measured traits. The yellow rust measurements evaluated under the field conditions including final rust severity (FRS), the average coefficient of infection (ACI), and area under disease progress curve (AUDPC) revealed that Giza-171, Misr-1, Gemmeiza-12, Shandweel-1, Sids-13, Line-1, Line-2, and Line-55 had better resistance. Based on heat sensitivity measurements, Line-1 and Line-2 followed by Line-35, Shandweel-1 and Line-55 were classified as more tolerant to heat stress compared with the remaining genotypes. The genotypes Line-55, Gemmeiza-12, Giza-171, Line-1, Line-2, and Misr-1 were able to maintain acceptable agronomic performance under timely and late sowing dates in all evaluated environments. Different statistical procedures were employed to explore the adaptability and stability of tested genotypes i.e., joint regression, stratified ranking, Wricke's Ecovalence values, cultivar superiority, additive main effects, and multiplicative interaction (AMMI), AMMI stability value, and genotype plus genotype-by-environment interaction (GGE). The applied stability parameters were quite similar for describing the stability of the evaluated wheat genotypes. The results indicated that Gemmeiza-12, Giza-171, Sids-12, Sids-13, Misr-1 Shandweel-1, Line-1, Line-2, and Line-55 were desirable and stable. The heatmap and hierarchical clustering were exploited for dividing the evaluated bread wheat genotypes into different clusters based on yellow rust resistance measurements, heat tolerance indices, and agronomic performance. Line-1 and Line-2 had the best performance for all rust resistance, heat tolerance, and agronomic performance followed by Giza-171, Line-55, Line-35, Gemmeiza-12, Shandweel-1, Misr-1, and Sids-13. In conclusion, our findings provide evidence of utilizing promising genotypes in rust resistance, heat tolerance, and agronomic performance in breeding programs for improving wheat grain yield stability mainly under climate change.

Rust diseases continue to cause economic losses to wheat production worldwide. Host-plant resistance significantly non-racespecific or combining race-specific and non-race-specific resistance is the most efficient, economic and ecofriendly way to control wheat rusts, besides eliminating the use of fungicides. Evidence on the effects of race-specific and non-race-specific resistance categories on stripe rust caused by Puccinia striiformis Westend. f. sp. tritici Eriks. and Henn and leaf rust (Puccinia triticina) development and in defending yield component losses in Indian wheat cultivars is still limited. Experiment was conducted to study the impacts of stripe rust and leaf rust on grain yield and yield components of some Indian wheat cultivars under artificial epiphytotic conditions. Cultivars with highly effective adult plant resistance to stripe rust viz.

“…Stripe rust, often known as yellow rust caused by Puccinia striiformis f. sp. tritici, is a devastating disease that affects wheat (Triticum aestivum L) in the major wheat-growing regions of the world [34,35]. The most cost-effective way to control the disease is to develop resistant wheat genotypes.…”

Stripe rust is the most harmful and prevalent disease among global wheat genotypes worldwide. It is induced by Puccinia striiformis f. sp. tritici. Its disease can also create new physiological races that attack resistant genotypes and constitute a severe danger to wheat output. The improvement of genetic resistance using Yr's genes through breeding programs that were not previously operated in Egypt in wheat genotypes is an effective strategy for preventing the disease. The marker-assisted selection with PCR-based methods was used to characterize the degree of slow rusting resistance for 38 wheat genotypes to stripe rust. The findings on the slow rusting genes support the resistance in the genotypes and can be used in wheat breeding programs to produce new stripe rust-resistant genotypes. The genotypes were classified into three major categories based on four disease parameters. The first group consisted of resistant genotypes. The second group had the lowest values of disease parameters and slower rusting. The third group showed the highest values for the disease parameters, including fast-rust genotypes, over the course of three seasons. The results revealed that the Super Kauz, Opata/Pastor, PBW 343/KKU, Opata 58, Chuan Nong 19, and IRAG genotypes enclosing Yr5, Yr15, Yr33, Yr37, Yr34, Yr51, Yr57, Yr4BL, and Yrkk genes were so resistant to stripe rust. while the Misr 3, Misr 4, Giza 168, Giza 167, Giza 170, Giza 171, Gemmeiza-9, and Gemmeiza-10 genotypes have the Yr9 gene. Giza 168, Giza 170, Gemmeiza-9, Gemmeiza-10, and Sids-14, containing the Yr18 and Yr29 genes. while the Yr17 and Yr27 genes were present in the Sids 13 and the most virulent genotype, respectively. In the backcrossing program, the genes were integrated into susceptible wheat genotypes, and different BC generations were created. From susceptible genotypes, stripe rust affected Gemmeiza 11, Misr 1, and Sids 14. These genotypes have high importance for farmers; they are cultivated in large areas worldwide, and the quality of their flour is high. Therefore, we intergraded Yr5 and Yr10 genes into these three genotypes using a breeding program. Finally, the characteristic of resistance improved and the high-yield production increased in studied wheat genotypes.
