Climate resilient breeding for high yields and stable wheat (Triticum aestivum L.) lines under irrigated and abiotic stress environments

Genotype × environment interaction and selection parameters for high yielding wheat genotypes under irrigated and heat stress environment

“…Heat stress also induces the production of growth retardants such as abscisic acid and ethylene. ROS along with growth retardants induces senescence related metabolic reaction that induces the earlier senescence in wheat (Bhandari et al, 2024).…”

“…The earlier senescence is associated with earliness in booting and heading which helps plant to escape from upcoming terminal heat stress (Bhandari et al, 2024;Pinto et al, 2016). Late booting and heading genotypes generally suffers from heat stress at critical phenological stages (Zahra et al, 2021).…”

“…The performance of wheat genotypes under irrigated and heat stress environment were classified using Ward method's based cluster analysis. To explore the association among high yielding clusters and agronomic parameters of wheat, PCA was plotted where, the association among agronomic parameters were presented based on cosine of angle between component vectors (Bhandari et al, 2024).…”

“…The optimum range of temperature for wheat during sowing is 10-15°C. The optimum temperature for growth is 16-22°C for anthesis and grain filling is 12-22°C, and during it is ripening from 21°C to 25°C (Bhandari et al, 2024). Climate change and a rise in the temperature would be going to have a great impact on global wheat production .…”

“…Identification of climate resilient wheat genotypes would help to achieve the SDG by United Nations to end hunger, malnutrition and all forms of micronutrient deficiencies (Bhandari et al, 2024).…”
