Arachis Hypogaea L

Groundnut (Arachis hypogaea L.) is one of the most important oils, food, confectionery, and feed crops due to its high oil quality and richness in all classes of nutrients. Coheritability helps in determining the pattern of coinheritance of two or more traits. This study was aimed at determining the coheritability of oil and yield traits to provide means of conducting improvement of oil traits through breeding for yield traits. The coheritabilities of the traits were estimated by a pooled analysis of covariance (ANCOVA) for agromorphological and oil traits. The result indicated that all oil traits have shown medium to high coheritability with oil content, oil quality, and seed yield. The coheritability and genetic advance of the three agronomically important traits in oil crops including oil content, oleic to linoleic acid (O/L) ratio, and seed yield (SY) is greater than oil content, linoleic acid, and SY can be further evidence showing that both oil content and oil quality traits can be improved with seed yield, indicating that there is the possibility of making a selection for genotypes with high oil content, oil yield, and oil quality with high seed yield traits.

Arachis Hypogaea L

Groundnut (Arachis hypogaea L.) is the world’s third important source of oil. A Genomic Selection Training Population (GSTP) comprising 340 genotypes was evaluated over four locations for two seasons to study genetic variability and association among agronomical and quality traits. GSTP exhibited significant variation among the genotypes, seasons and G x E interaction. Moderate to high magnitude of genotypic coefficient of variation and phenotypic coefficient of variation coupled with high heritability was observed for most quality traits. The first 7 components of PCA analysis contributed more than 75% cumulative variability. The training population grouped into three clusters in both the seasons. The number of pods/plant, pod and seed yield/plant were significantly and positively associated with each other, while test weight had negative association with number of pods/plant and had positive association with pod and seed yield during rainy season of 2015. The significant positive correlation was also observed between oil, linoleic acid and stearic acid; similarly, linoleic acid had positive association with stearic acid and palmitic acid. Significant negative correlation was observed between oil and protein content, oleic acid and linoleic acid content. The superior genotypes, namely, ICG 5221, ICGV 01393, ICGV 07220, ICGV 97120, ICGV 06420, ICG 9507, ICGV 06188 and ICGV 00440 were best performer for yield, yield components and nutritional quality traits while ICG 2381 and ICG 5221 recorded a better performance for oil content. The rainy season was found to have an advantage for vegetative, physiological growth, oil content, oleic and oleic to linoleic ratio while the post-rainy season led to forced pod filling and reduced maturity.

Abstract The quality of edible oils is now receiving increasing consideration from consumers and processors. The present study was conducted to investigate the effects of environments on oil content and fatty acid composition in peanut. The correlation between oil content and oil quality parameters was also studied. Thirteen peanut (Arachis hypogaea L.) genotypes were grown in 12 environments for the study. Soils at experiment locations differed significantly for pH, EC, and N, P, Zn, Mn, and Fe contents. Significant genotype, environment, and genotype x environment interaction effects were observed for oil content, individual fatty acid contents, and derived oil quality parameters. The original range of 34-54% of oil content based on one season/location evaluation in these lines was not repeatable, and ranged from 45-50% in multilocation evaluation. Oil content was positively correlated with soil pH and Fe content. The correlation of oleic and linoleic acid content with soil pH and Fe content was positive in the former and negative in the latter. The oil content was positively correlated with O/L ratio. Oliec and linoleic acid contents were negatively correlated. Selection for reduced linoleic acid level in genotypes would also reduce levels of total long chain saturated fatty (TLCSF) acids. Of the thirteen genotypes tested, ICG 5856, ICG 5369, and ICGV 87124 could be used in breeding for improved oil quality.

This study was conducted at the experimental area of the Cukurova University, Faculty of Agriculture in 2017, 2018 and 2019 in Adana (Mediterranean Region)-Turkey. The objective of this study was to compare of fatty acids composition and oil quality factors of different market type peanut (Arachis hypogaea L.) varieties grown as a main crop. Four different market type peanut varieties, including Virginia (Halisbey), Runner (G.Green), Spanish (Florispan) and Valencia (G.Red) were used as plant material in this research. The experimental design was a randomized complete block design with three replications. Oil content, fatty acids composition such as oleic acid, linoleic acid, stearic acid palmitic acid and oil quality factors such as Oleic/linoleic acid ratio (O/L) and iodine value (IV) of peanut seed oil were investigated. According to a three-year results; the oil content of the peanut varieties varied between 45.38% and 51.28%. The total saturated fatty acid was higher in Spanish and Valencia types than Virginia and Runner types. On the other hand, the total unsaturated fatty acid was higher in Virginia and Runner types than the others types.

Abstract Undesirably low oleic acid and high linoleic acid concentrations in seed oil are typical of Valencia peanuts (Arachis hypogaea L.) produced in a cool, short-season climate. Improved oil quality may be achieved by incorporating Virginia type germplasm into adapted Valencia peanuts. The objectives of this study were to determine the oil quality of nine Valencia and four Virginia peanut lines, evaluate their combining ability for oil concentration, fatty acid composition of the oil, and several taxonomic characters, and assess the potential for developing cultivars adapted to Ontario with improved oil quality. General combining ability (GCA) of the Virginia parents significantly exceeded specific combining ability (SCA) for all fatty acids except arachidic, and also for oleic/linoleic (O/L) ratio, days to first flowering, days to full flowering, and branching pattern (R/R + V ratio). GCA of the Valencia parents significantly exceeded SCA only for oil concentration. Significant SCA estimates were found for oil concentration, palmitic and oleic acids, O/L ratio, and height of the main axis (first date). Significant heterosis was detected for all taxonomic characters except days to first flowering. Genetic variability for all characters except arachidic acid indicates that the development of Ontario cultivars with improved oil quality, in terms of higher oil content and reduced linoleic acid levels, appears feasible through breeding efforts.

Background: Blackgram is an important pulse crop consumed in the form of fermented cuisines especially in south India. Yield being a complex trait, is highly influenced by environment. Studies on environmental influence on batter quality are rare. Hence, the current study was taken up to identity stable genotypes over environments with respect to yield and batter quality traits.Methods: In the present study, 32 blackgram genotypes were evaluated for yield performance and batter quality traits during kharif 2019, rabi 2019-20 and summer 2020 at National Pulses Research Centre, Vamban. Pooled analysis of variance and stability analysis was performed by AMMI and GGE biplot.Result: From stability analysis, it was evident that the genotypes, ACM BG 17-001, ACM BG 17-006 and ACM BG 18-010 expressed high mean value and stability for seed yield. In case of idly batter volume, the genotypes, ACM BG 17-001 was stable hence may be recommended for all season cultivation. The trait, vada batter volume was found to be with non-significant GxE interaction and hence do not interact with the environment. Among the environments under study, summer season was the most favourable environment for seed yield. However, for idly batter quality, kharif season was the most favourable environment.

Abstract Five peanut (Arachis hypogaea L.) genotypes, Southern Runner, Dixie Runner, Florunner, UF82206, and UF714021, were grown for three years, 1982–1984, near Gainesville, Florida without fungicide applications. Three digging dates, averaging 105 days after planting (DAP), 118 DAP, and 132 DAP, were used each year to determine the effects of early harvest as a management practice for peanut production under leafspot pressure. The different digging dates had no effect on fatty acid composition of the five genotypes, and had only minimal effect on the oil content and iodine value. The largest oil quality differences in this study were due to differences among genotypes and year-to-year variation. The earliest digging date tended to reduce market grade characters, but major pod yield differences were the result of genotype × digging date interactions. Genotypes with little or no resistance to leafspot diseases, such as Florunner and UF 714021, produced nearly 3000 kg/ha without leafspot control up to 118 DAP and then had sharp yield decreases, while resistant genotypes such as Southern Runner and UF 82206 continued to produce pod yields of 3000 kg/ha or higher up to 132 DAP.
