Cowpea (<i>Vigna unguiculata</i> (L.) Walp.) is an important legume crop cultivated in many regions of Nigeria. It serves as a source protein, nutrients and income for communities. However, its production yield potential are severely affected by drought which has been prevalent constraint over the years, posing significant threat to cowpea food security hence need develop mutant lines that can withstand conditions continuous sustenance lives livelihoods. This study aimed determine effects mutagens on tolerance indices selected treated with gamma irradiated Ethyl Methane Sulphonate (EMS) collected from gene bank Plant Biology, Federal University Technology Minna, Niger State. These were subjected water stress two weeks assessed potential. The revealed rays EMS had significantly indices. Geometric Mean Productivity (GMP) ranged 4.11 (V2G4) 7.11 (V3EG3).

The increasing frequency of heat stress events due to climate change disrupts all stages plant growth, significantly reducing yields, especially in crops like mung bean (Vigna radiata (L.) R. Wilczek). Mung beans are vital grain legumes Southeast Asian countries and crucial for food security. Thus, it is essential understand the physiological yield-related trait responses genotypes harness germplasm with enhanced tolerance mitigate impact rising on yield. This study assesses ten diverse grown under three temperature regimes (34/25 °C, 39/30 42/30 °C) growth chambers. We found significant genetic variability phenological, physiological, traits control conditions. Severe leaf damage, indicated by high cell membrane injury, reduced chlorophyll index, diminished fluorescence, was observed °C Similarly, reductions yield component traits, including effective pods per plant, total seeds single-seed weight, seed were evident tested Correlation analysis suggested that selecting higher index increased canopy depression could help identify varieties pod yields stress. Clustering identified PI 425425, 425238, 363361 as potential candidates breeding programs develop climate-resilient cultivars.

Selecting genotypes tolerant to high temperatures is an important measure for agricultural maintenance and production in climate change scenarios. Thus, this study aimed select cowpea increased air temperature. A total of 20 were used, cultivated under temperature regimes 20–26–33 °C 24.8–30.8–37.8 a completely randomized experimental design 2 × factorial scheme (temperature genotypes). The BRS Inhuma, Bico-de-Ouro-17-45, Guariba, Imponente did not show significant differences the analyzed physiological responses increase Bico-de-Oouro-17-19, Bico-de-Ouro-17-44, showed tolerance as thermal stress affect production. Pingo-de-Ouro-17-48, MNC00-595F-27, MNC06-895E-1, MNC09-981B-2 reduced water efficiency by −26.85, −25.19, −40.04, −60.37%, respectively, due results obtained work represent pre-selection that are temperatures, with indicated based on interaction productive responses. There urgent need maintain scenarios ensure systems’ sustainability food security.
