“…It has been found that peanut varieties with high oleic acid could maintain better taste quality and long‐term stability of seed quality during storage (Liu, Chen, et al, 2019; Martín et al, 2018; Wen et al, 2018). And the oleic acid content gradually increased while linoleic acid showed a downward trend (Abbas et al, 2020; Bishi et al, 2013). Similar rules were also obtained in this study.…”

To investigate the effects of waterlogging stress on grain nutritional quality and pod yield, peanut plants were waterlogged for 3 and 6 days at 7, 14, 21, 28, 35, 42, 49, 56 and 63 days after gynophores touched the ground in 2019 and 2020. Results revealed that compared with the control treatment, the oil and starch content in grain increased, while crude protein and soluble sugar content decreased under waterlogging. Waterlogging stress increased the unsaturated fatty acids content but decreased the saturated fatty acids, essential amino acids, non-essential amino acids and total amino acids content. In addition, waterlogging stress decreased the total pod number per plant by 6.78%-49.33%, 100-pod weight by 1.11%-14.08% and 100-grain weight by 1.85%-16.41%, which caused a 34.33%-55.90% reduction in pod yield per plant.After the gynophore touched the ground for 7 days, waterlogging had a greater negative effect on grain nutritional quality, and longer waterlogging duration led to greater yield reduction. In summary, waterlogging stress caused peanut yield reduction and grain quality deterioration.

The forty-five genotypes of groundnut were evaluated at Field Experimentation Centre of the Department of Genetics and Plant Breeding, Naini Agricultural Institute, SHUATS, Prayagraj (U.P.) during kharif, seasons of 2021-22 and 2022-23 in four artificially created environments by four different dates of sowing considered as E-I, E-II, E-III & E-IV. The present experiment was carried out in Randomized Block Design with three replications and involved recording observations on 17 yield and its contributing characters. Identifying stable-performing genotypes in the changing environmental scenario is of paramount importance in modern breeding materials. Crop improvement programme mostly depend on the identification of superior and stable genotypes. Mean sum of squares due to environment were found to be substantially distinct for all the traits and the mean sum of square due to genotype were found to be significant for all the characters. The regression coefficients (bi) of the genotypes ranged from -3.40 to 2.52 and the deviation from regression (S2di) ranged from -1.01 to 1.56. Stability parameters of various traits revealed that GJG-18, RG-574 and RG-559-3 pod yield per plant and RS-1 oil content showed high mean performance and regression coefficient close to unity and non-significant deviation from regression stable under overall environments. Thus indicating the importance of non-linear components in determining interaction of the genotypes with environments in the present study according to the Eberhart and Russell (1966) model.

The forty-five genotypes of groundnut were evaluated at Field Experimentation Centre of the Department of Genetics and Plant Breeding, Naini Agricultural Institute, SHUATS, Prayagraj (U.P.) during kharif, seasons of 2021-22 and 2022-23 in four environments condition of Randomized Block Design with three replications. Observations were recorded on 17 yield and its attributing characters. Analysis of variance revealed the presence of significant amount of variability among the groundnut genotypes. The findings of the ANOVA observed a highly significant variation (p ≤ 0.01) for all the traits evaluated. Maximum genotypic coefficient of variation (23.12) and phenotypic coefficient of variation (25.92) was recorded for number of branches per plant. The topmost heritability was recorded for hundred pod weight (98.70%) followed by days to maturity (98.60%) with genetic advance hundred pod weight (41.47%) and days to maturity (24.34%). The traits with least influenced by the environment as well as governed by the additive genes and direct selection for improvement of such traits can be beneficial. Analysis of genetic diversity using Mahalanobis' D2 statistic was carried out in 45 genotypes. These genotypes were grouped into seven clusters. Cluster IV had the maximum number of genotypes. The analysis further indicated that the genotypes of common geographic origin or same location were grouped into different clusters which suggested a lack of relationship between genetic and geographic diversity. Plant height showed relative contribution was the highest 16.67%, then followed by hundred pod weight (14.95%) and pod yield per plant (8.59%).
