“…While on the other hand, check cultivar Valencia-C (Val-C) showed lesser yield. These results are well synchronizing with our earlier study on the pod yield performance of different peanut genotypes under different soil and regional conditions 9 , where C-76 produced more than Val-C in rainfed conditions without irrigation but there is a considerable reduction in C-76 yield by 15-20% compared to Val-C, which was up to 50-70% reduction in yield compared to complete irrigation 9 . Another study in peanut 23 showed a lower yield of Valencia-type pods (PI 536121) under drought conditions.…”

Based on the observed phenotypic variations from our previous 9 and present drought studies, two genotypes-C76-16 (C-76, runner type) and Valencia-C (Val-C, Valencia type) were identified as the contrasting genotypes towards drought response and thus selected for transcriptome studies. Leaf samples for the RNA-seq were collected from C-76 and Val-C genotypes in 2014 in three biological replicates for transcriptome profiling and generated ~369 million raw reads.…”

“…The differences in the type of physiological response facilitate the plant either to be tolerant or sensitive towards the stress conditions. The yield of peanut among different genotypes under drought stress was screened to assess the variation of tolerance 8,9 . Different studies have reported drought-tolerant peanut genotypes, however, it is essential to check the performance of these genotypes in target locations such as West Texas and eastern New Mexico regions which faces frequent problem of limited water resources.…”

Drought is one of the main constraints in peanut production in West Texas and eastern New Mexico regions due to the depletion of groundwater. A multi-seasonal phenotypic analysis of 10 peanut genotypes revealed C76-16 (C-76) and Valencia-C (Val-C) as the best and poor performers under deficit irrigation (DI) in West Texas, respectively. In order to decipher transcriptome changes under DI, RNAseq was performed in C-76 and Val-C. Approximately 369 million raw reads were generated from 12 different libraries of two genotypes subjected to fully irrigated (FI) and DI conditions, of which ~329 million (90.2%) filtered reads were mapped to the diploid ancestors of peanut. The transcriptome analysis detected 4,508 differentially expressed genes (DEGs), 1554 genes encoding transcription factors (TFs) and a total of 514 single nucleotide polymorphisms (SNPs) among the identified DEGs. The comparative analysis between the two genotypes revealed higher and integral tolerance in C-76 through activation of key genes involved in ABA and sucrose metabolic pathways. Interestingly, one SNP from the gene coding F-box protein (Araip.3WN1Q) and another SNP from gene coding for the lipid transfer protein (Aradu.03ENG) showed polymorphism in selected contrasting genotypes. These SNPs after further validation may be useful for performing early generation selection for selecting droughtresponsive genotypes.

“…The oil contents and palmatic acid were the highest in genotype BARI-2011. Indeed, the oil contents of genotypes are affected by the production location, growing season, soil temperature, soil moisture and soil fertilization (Dwivedi et al, 1996;Singkham et al, 2010;Boydak et al, 2010;Arioglu et al, 2016;Zurweller et al, 2018) and the same was observed in this study.…”

“…In addition, the selection of peanut cultivars during the hybridization experiments largely relied upon the performance of yield parameters (e.g. pods per plant, seeds per pod and seed weight) in the parent cultivars (Reddy et al, 1993;Zaman et al, 2011;Zurweller et al, 2018). Nutritional quality of peanut is also very important as storage capability of peanut mainly depends on concertation of saturated and unsaturated fatty acids like linoleic acid, oleic acid and plamatic acid (Gulluoglu et al, 2016).…”

Exploring the genetic variation is the base of peanut (Arachis hypogaea L.) breeding program since peanut is an important food legumes and oilseed crop of the world, but its breeding is neglected compared to major oilseed crops. A field study was conducted to characterize the genetic variation and correlation among important yield and quality related traits of peanut under arid climate conditions during two consecutive years 2015 and 2016. Results revealed that a higher genetic diversity is present among the tested genotypes with respect to pod yield, oil contents and fatty acid composition. The highest number of leaves per plant, pods per plant, seed weight, pod yield, oil contents and palmitic acid were recorded in genotype 'BARI-2011' as compared with the other peanut genotypes. However, 100-seed weight was the maximum in genotype 'Golden'. Among the years, the morphological, yield parameters, oil contents and palmitic acid was the higher in second year than those of the first year of experimentation. In conclusion, the high genetic variability has been found among the peanut germplasms may contribute to develop a high yielding variety with good seed quality.

BACKGROUNDThe accumulation of microplastics in agricultural soil poses a threat to the sustainability of agriculture, impacting crop growth and soil health. Due to the geocarpy feature of peanut, geocarposphere soil environment is critical to pod development and its nutritional quality. While the effects of microplastics in the rhizosphere have been studied, their impact on peanut pod in the geocarposphere remains unknown. Biochar has emerged as a potential soil agent with the ability to remediate soil contamination. However, the mechanisms of biochar in mitigating the toxic effects of microplastics‐contaminated geocarposphere soil on peanut pod development remain largely unexplored.RESULTSWe evaluated the peanut pod performance and microbiome when facing microplastics contamination and biochar amendment in geocarposphere soil. The results showed that microplastics present in geocarposphere soil could directly enter the peanut pod, cause pod developmental disorder and exert adverse effects on nutritional quality. Aberrant expression of key genes associated with amino acid metabolism, lipid synthesis, and auxin and ethylene signaling pathways were the underlying molecular mechanisms of microplastics‐induced peanut pod developmental inhibition. However, these expression abnormalities could be reversed by biochar application. In addition, peanut geocarposphere microbiome results showed that biochar application could restore the diversity of microbial communities inhibited by microplastics contamination and promote the relative abundance of bacteria correlated with pathogen resistance and nitrogen cycle of geocarposphere soil, further promoting peanut pod development.CONCLUSIONThis study demonstrated that biochar application is an effective strategy to mitigate the toxic effects of microplastics‐contaminated geocarposphere soil on pod development and nutritional quality. © 2023 Society of Chemical Industry.
