“…Abiotic stresses such as moisture, high/low temperature, salt, and nutrition stress, in maize, have resulted in 17-60% of yield losses in various countries [83]. Although the crop possesses inherent resistance to severe conditions, abiotic stresses hamper its performance, corresponding to about 10-15% yield losses [84].…”

Climate change has had a significant impact on many ecosystems worldwide, prompting native population species to adapt to the current weather patterns eventually. Pre-existing genetic variation in populations explains part of this adaptation. Still, recent studies have shown that new stable phenotypes can be generated through epigenetic modifications in just a few generations, thereby contributing to the stability and survival of plants in their natural habitat as they eventually adjust to the surrounding impacts. The state of chromatin inside plant cells varies, allowing cells to fine-tune their transcriptional profiles to better adapt to stimuli from the external environment. Within a cell, chromatin state changes such as post-transcriptional histone modifications and variations, DNA methylation, and non-coding RNA activity are all examples of chromatin state alterations that may epigenetically dictate certain transcriptional outputs. Recent advances in the field of ‘Omics’ in major crops has made it easier to identify epigenetic changes and their impact on plant responses to environmental stresses. These epigenetic mechanisms thus play an important role in improving crop adaptation and resilience to changing environments. This variation that has emerged can thus be exploited in crop breeding, ultimately leading to the generation of stable climate-resilient genotypes.

“…Diminution in yield is the key focus of breeders and expanding the yield recital, especially under water stress conditions is their major objective (Pakniyat, 2010). Barley Hordeum vulgare L.) Although, it is an abiotic stress-tolerant crop in comparison with other crops yet drought, salinity, sodicity, acidity, water logging, and heat affect its production and productivity (ALI, 2022;BASHIR et al, 2023;Fatima et al, 2023;Rani et al, 2018). However, (Alghabari et al, 2015) testified that the major factors decreasing crop production and development are stresses of heat, drought, and diseases.…”

The rise of sustainable barley production dictates the development of new barley varieties with enhanced yield and resistance to biotic and abiotic stresses. WRI, AARI, Faisalabad, Pakistan has released several barley varieties together with JAU-21 since its formation. Jau-21 is a six-row barley variety that can grow and ripen in a shorter time was selected from the international nursery GSBSN received from the International Center for Agriculture Research and Dry-land Area, Egypt during 2014-15. The revealed genotype with variety code B-15018 was further appraised in preliminary and regular during 2015-17 which super seated 21.65% than Haider-93 check on average bases. In the Punjab uniform barley yield trial, the proposed line outclassed the same check varieties by 20.29% over different settings of Punjab in 2017-18. It was further tested for yield and disease constancy in the national uniform barley yield trial, it excelled at 10.31 and 4.46 % over Haider-93 and Sultan-17, respectively during 2018-19 and 14.66 and 9.93% over Jau-87 and Jau-17, respectively in 2019-20 %. It can tolerate rust by displaying disease reactions from 0 to traces rather than 100 MS over check. Agronomic judgments and quantitative and qualitative analyses were also performed during 2017-18 to 2019-20. Due to its bold grain, auspicious yield performance, and appealing rust resistance trait over multi-location, the Punjab Seed Council approved B-15018 in 2021 with the name “Jau-21” for general cultivation in irrigated and rainfed areas of Punjab, Pakistan.

Rising temperature has adversely affected wheat production globally. In this realm we studied various morpho-physiological traits governing heat tolerance using thirty bread wheat RILs developed via crossing LOK-1 x HUW- 468, LOK 1 x HUW 234 and Raj-4014 x PBN-51. Correlation studies reflected that traits like number of tillers per plant, plant height, and chlorophyll content were significantly positive correlated with grain yield per plant, on the other hand, path coefficient analysis revealed that the chlorophyll content (0.362) and tillers per plant (0.222) showed a significant positive correlation with grain yield per plant, whereas significant negative correlation for grain yield was exhibited with relative water loss (-0.392) and canopy temperature (-0.402) at genotypic level.
