“…Manipulating or reducing phenological development, for instance, by adjusting sowing time, is a successful strategy that enables the crop to avoid heat stress during the critical reproductive period (Yadav et al, 2022). A recent multi‐environment study evaluating 80 mungbean genotypes across three agro‐ecological zones in Pakistan identified days to flowering, maturity and seeds per pod as key traits influencing yield under heat stress at the flowering stage (Iqbal et al, 2021). These findings suggest that early maturing genotypes performed best under heat stress conditions.…”

Mungbean (Vigna radiata (L.) R. Wilczek var. radiata) is a significant food and cash crop grown in tropical and subtropical regions. Mungbean production and consumer demand have increased substantially over the last two decades, owing to its agronomic, nutritional and economic benefits. Despite increased breeding efforts and the expansion of mungbean production in various agro‐climatic regions, further production is hindered by low yield and variability, which is partly attributed to the impacts of abiotic stress. Abiotic stress impacts on the physiology, morphology and reproductive ability of mungbean which influences yield. Exposure to abiotic stresses at the reproductive stage is considered the most critical for yield production. In this review, we evaluate how abiotic stress impacts mungbean growth and productivity when occurring during the reproductive stage and traits that may confer adaptation. We present the limitations of current research including limited number of genotypes, lack of field experiments and detailed experimental information. We highlight the opportunities to exploit new tools and technologies, such as high‐throughput phenotyping platforms, gene editing, and genomic selection, to accelerate breeding efforts to develop more resilient mungbean cultivars for today and tomorrow.

“…As heat stress reduced grain yield due to loss in NP, NSP and HSW; interestingly, ndings of this study showed that DM had a negative association with NP, PL, HSW and SY. Thus, it is suggested that early maturing genotypes can handle high-temperature stress effectively and should be the primary target trait to develop heat-tolerant lines (Hanif and Wahid 2018;Iqbal et al 2021).…”

“…Yield was positively associated with the morphological traits such as PH, SPP, and HSW under heat-stress environment, indicating heat tolerant genotypes have high NP and HSW. Hence, it is suggested that selection could be made based on performance of such traits as rise in these traits can signi cantly enhance the grain yield of mungbean (Iqbal et al 2021). As heat stress reduced grain yield due to loss in NP, NSP and HSW; interestingly, ndings of this study showed that DM had a negative association with NP, PL, HSW and SY.…”

Heat stress due to climate change could be a critical factor for plant growth as it disturbs flowering time and reduces the crop yield. Therefore, it is crucial to investigate the performance of crop genotypes under heat stress condition. The present research was conducted to assess heat tolerance in 25 mungbean genotypes. The experiment was performed in randomized complete block design on two sowing dates: normal sowing (39°C/26°C) and late sowing for heat treatment (47°C/30°C). All genotypes showed significant variations for treatments, genotypes, and genotypic × treatment interactions. Significantly positive correlation of plant height (0.73**, 0.44**), number of seeds per pod (0.74**, 0.45**) and 100-seed weight (0.89**, 0.43**) with seed yield was recorded under both control and stress conditions, respectively. Principal component analysis revealed a high contribution of seed yield, yield index, geometric mean productivity, tolerance, stress tolerance index and mean productivity for PC1 and PC2. Cluster analysis revealed that genotypes retained in cluster 1 and 2 could be utilized to combine yield and stress stability indices in breeding programs. Findings from multivariate analysis suggested that MN-98, MN-108, MN-2011, MN-2225, MN-93 and MN-203 are potential cultivars under heat stress. Hence, these genotypes could be used as genetic resources for transferring heat tolerance to elite genotypes that are sensitive to high temperatures.

The objective of this study was to assess the grain yield performance and agronomic traits of local pea genotypes improved by different province research institutes under multiple environments, in order to further exploit high yield potential elite pea varieties with tolerance to biotic and abiotic stresses, and which are widely suitable for planting in spring sowing areas in China.…”

Field pea (Pisum sativum L.) is one of the most important pulse crops, and is widely grown in North China. To exploit potential pea varieties suitable for growing in spring planting areas, a set National Regional Trials of Spring Pea Genotype was carried out under irrigated and rainfed environments across seven locations. Grain yield and agronomic traits of fourteen pea cultivars were evaluated. Analysis of variance indicated that the effect of genotype, environments and genotypes × environments interaction was significant (p < 0.01). Results of GGE biplot analysis showed that the first and second principal components accounted for 77.5% and 14.5%, respectively. Genotypes accounted for just 14.7% of the variation in seed yield, while environments accounted for 39.9%, and genotypes × environments interaction accounted for 45.5% of the variation. Investigating the polygon view led to the identification of five superior genotypes and five productivity environments. Superior genotypes and key environments for grain yield were determined using a general linear model. The significant genotypes × environments interaction effects indicated the inconsistent performance of genotypes across the tested environments. Among the tested genotypes, significant differences were observed for grain yield and yield-related traits. The semi-leafless pea variety Longwan 10 was observed the highest yield (3308 kg/ha) over seven locations. Dingwan 12, Dingwan 13, Tongwan 5, Kewan 7 showed higher, stable grain yield than the overall mean of genotypes and check variety Zhongwan 6. The most representative and productivity regions for grain yield of field pea were Yondeng, Qitai, Liaoyang, Dingxi and Tangshan. These findings represent a comprehensive analysis of yield and stability of spring pea varieties and growing locations, which may be useful for national and international pea improvement programs.
