“…This could indicate that in genotypes with slightly reduced oil and increased protein content, nutritive value of seeds could be higher, due to lower phytate and increased GSH content. This was supported by the findings of Dwivedi et al [12], who also observed negative correlation between oil and protein content in peanut seeds.…”

“…Obtained results indicated that seeds of examined peanut landraces could be considered as high oil and protein food, consisting of about 66.6% to 74.2% oil + protein content. Dwivedi et al [12] ascertained that oil and protein content negatively correlate in peanut seeds, which was confirmed with our results, where high oil genotypes, like P1, P7, P8, P9, and P10 have also the lowest protein content. Compared to genotypic variations, environmental factors have shown to have more pronounced effect on variations in oil content of peanut seeds [11].…”

“…Chemical properties of grain are under high genotypic and environmental impact, reflected in induced variations in oil content, individual fatty acid contents, and derived oil quality parameters [11]. Dwivedi et al [12] reported significant and negative correlation between oil and protein contents, as well as significant linear increase in oil content followed by seed mass increase. However, no such relationship was observed for protein content.…”

Background: Chickpea and peanut are two legume species not frequently used in human diets. Chickpea is rich in starch and proteins, while peanut is mainly a source of oils and proteins and they could be successfully used as protein sources in vegetarian diets. Seeds of 19 chickpea and 13 peanut landraces were colorimetrically analyzed in respect to antioxidant content (i.e., free soluble phenolics, total glutathione, and phytate). Oil and protein contents in grain were also determined. Results: Free soluble phenolics content varied in range from 520 to1,050 mg kg −1 in peanut and from 720 to 1,370 mg kg −1 in chickpea. Total glutathione content ranged from 1,495 to 2,365 mmol kg −1 in peanut and from 955 to 1,232 mmol kg −1 in chickpea. Relatively low content of phytic phosphorus was found in grain of both species, ranging from 2.5 to 4.5 g kg −1 in peanut and from 1.4 to 3.0 g kg −1 in chickpea, respectively. Considering the lack of data for phytate variability in Macedonian chickpea and peanut local landraces up to date, the observed high variation in phytic phosphorus content could represent the great basis for further breeding programs for phytate decrease in seeds of those genotypes. This is significant, since phytate is an important antinutrient which affects availability of mineral elements. Regression analysis revealed positive and highly significant interdependence between oil content and total glutathione in chickpea seeds, as well as between oil content and phytic phosphorus in peanut seeds. In chickpea, significant and negative correlation between oil and phytic phosphorus content was also observed. Conclusions: Results obtained indicated that chickpea genotypes with higher oil content could have increased nutritional value due to higher glutathione and lower phytate content observed. However, lower level of phytate content, along with higher level of soluble phenolics and total glutathione found in peanut seeds with lower oil content, indicated higher digestibility and increased antioxidant activity of those genotypes.

“…In groundnut breeding program selections are carried out either for high oil (for oil milling) or high protein and low oil (for food and confectionary uses) to meet two distinct end-uses. Similar observations were also reported by others (Dwivedi et al, 1990, Sarvamangla et al, 2010. Hundred seed weight had significant negative association with oil content (r g =-0.34 & r p =-0.20), and significant positive association with protein content (r g =0.36 & r p =0.20).…”

A set of 340 diverse groundnut genotypes included in Genomic Selection Panel (GSP) was used to evaluate genetic parameters and trait associations for resistance to rust and late leaf spot (LLS) along with yield and nutritional quality traits. The findings revealed high genetic variability coupled with high heritability and genetic advance as percent of mean (GAM) for resistance to both the diseases and yield traits, whereas low variability for nutritional quality traits with high heritability and low GAM. Disease severity scores for rust and LLS at 90 days after sowing (DAS) were negatively associated with yield, indicating pod yield penalty, thus deploying host-resistance for rust and LLS is a good strategy to plug the pod yield losses and reduce the input cost. It is possible to simultaneously improve the number of pods per plant and hundred kernel mass that contribute to pod yield as no trade-offs were detected between them. The association of oil and protein content with pod yield showed no tradeoffs, suggesting the possibility of simultaneous improvement of pod yield either with high oil or protein content. In breeding programs that target development of groundnut varieties to meet two distinct end-uses, oil milling, and food and confectionery, selection for either high oil (for oil purpose) or high protein and low oil (food/confections) will be efficient, as an inverse association between oil and protein content was observed. The use of disease score at 90 DAS for rust and LLS is effective and optimizes resources to make selection decisions in breeding as positive association among disease severity scores at different periods (75, 90 and 105 DAS) was observed.

“…Correlations between oil content and seed mass, pod weight, and pod length were not significant. Dwivedi et al [5] determined that high oil content can be maintained when indirectly selecting for large seed size. Other studies have reported negative correlations between seed size and oil content in peanut [6,7].…”

Peanut (Arachis hypogaeaL.) has the potential to become a major source of biodiesel, but for market viability, peanut oil yields must increase. Oil yield in peanut is influenced by many different components, including oil concentration, seed mass, and mean oil produced per seed. All of these traits can potentially be improved through selection as long as there is sufficient genetic variation. To assess the variation for these traits, a diallel mating design was used to estimate general combining ability, specific combining ability, and heritability. General combining ability estimates were significant for oil concentration, weight of 50 sound mature kernels (50 SMK), and mean milligrams oil produced per SMK (OPS). Specific combining ability was significant for oil concentration. Reciprocal effects were detected for OPS. Narrow-sense heritability estimates were very high for oil concentration and 50 SMK and low for OPS. The low OPS heritability estimate was caused by the negative correlation between oil concentration and seed size. Consequently, oil concentration and seed mass alone can be improved through early generation selection, but large segregating populations from high oil crosses will be needed to identify progeny with elevated oil concentrations that maintain acceptable seed sizes.
