An olive breeding program was started in Tunisia in 1993 in order mainly to improve the fatty acid composition of the local cultivar ‘Chemlali Sfax’. ‘Zeitoun Ennour’ is a new cultivar obtained from a cross between ‘Chemlali Sfax’ and the local dual-purpose use cultivar ‘Chemchali Gafsa’. The morphological study of this cultivar showed that eleven characters dealing with fruit and endocarp differed from ‘Chemlali Sfax’, mainly regarding to their respective weights. This new cultivar had the same sensitivity to Verticillium dahliae Kleb and earlier bearing than the original variety. Its olive production was considered as high as for ‘Chemlali Sfax’ but with partial self-compatibility and late maturity. The new cultivar realized a net improvement in comparison with the original cultivar particularly regarding its fatty acid composition with very high oleic acid content (>75 %) and low palmitic and linoleic acid contents (<10 %). The new cultivar was recently released and will be available for growers as soon as possible.

Peanut skins are a considerable waste product with little current economic value or use. We aimed to determine the dietary effects of peanut skins on layer production performance and egg quality and chemistry of the eggs produced. Two hundred commercial hens were randomly assigned to four treatments (five replicates) and fed ad libitum for 8 weeks: conventional control diet, diet containing 24% high-oleic peanut (HOPN), diet containing 3% peanut skin (PN Skin), and a diet with 2.5% oleic acid (OA). Hens fed the HOPN diet had significantly reduced body weights relative to the control and PN Skin treatments, producing fewer total eggs over the 8-week experimental period. Eggs weights were similar between the control and PN Skin treatments at weeks 2 and 4, while eggs from the PN Skin treatment group were heavier than other treatments at weeks 6 and 8 of the experiment. Eggs produced from the HOPN treatment had reduced saturated fatty acid (FA) content in comparison to the other treatment groups, while similar between PN Skin and control eggs at week 8 of the experiment. This study suggests that PN skins may be a suitable alternative layer feed ingredient.

Background: There is concern that the PUFA composition of ready-to-use therapeutic food (RUTF) for treatment of severe acute malnutrition (SAM) is suboptimal for neurocognitive recovery. Objective: We tested the hypothesis that RUTF made with reduced amounts of linoleic acid, achieved using high oleic (HO) peanuts, with or without added DHA, improves cognition when compared to standard RUTF (S-RUTF). Methods: A triple-blind, randomized, controlled clinical feeding trial was conducted among children with uncomplicated SAM in Malawi with 3 types of RUTF; DHA-HO- RUTF, HO-RUTF and S-RUTF. The primary outcomes, measured in a subset of subjects, were the Malawi Developmental Assessment Tool (MDAT) global and 4 domain (gross motor, fine motor, language and social) z-scores and a modified Willatts problem solving assessment (PSA) intention score for 3 standardized problems, measured 6 months and immediately after completing RUTF therapy, respectively. Plasma fatty acid content, anthropometry and eye tracking were secondary outcomes. Comparisons were made between the novel PUFA RUTFs and S-RUTF. Results: Among the 2565 SAM children enrolled, global MDAT z-score was -0.69 ± 1.19 and -0.88 ± 1.27 for children receiving DHA-HO-RUTF and S-RUTF, respectively (difference 0.19, 95% CI 0.01 to 0.38). The gross motor and social domains had higher z-scores among children receiving either DHA-HO-RUTF than S-RUTF. The PSA problem 3 scores did not differ by dietary group (Odds ratio 0.92, 95% CI 0.67 to 1.26 for DHA-HO-RUTF). After 4 weeks of treatment, plasma phospholipid EPA and a- linolenic acid were greater in children consuming DHA-HO-RUTF or HO-RUTF when compared to S-RUTF (for all 4 comparisons P values < 0.001), but only plasma DHA was greater in DHA-HO-RUTF than S-RUTF ( P <0.001). Conclusions: Treatment of uncomplicated SAM with DHA-HO-RUTF resulted in an improved MDAT score, conferring a cognitive benefit six months after completing diet therapy. This treatment should be explored in operational settings.

We investigated the dietary effects of high-oleic peanuts (HOPN) or oleic fatty acids (OA) on older production hen performance, egg mass and quality, and lipid composition. A total of 99 laying hens were divided between three treatments and fed ad libitum for 8 weeks: (1) Conventional diet; (2) HOPN diet; (3) OA diet. Body weight (BW) was measured at weeks 1 and 8, and feed, egg weights (EW), and egg quality parameters were collected. Data was analyzed by analysis of variance at p < 0.05 significance level. There were no treatment differences in 8 week BW, feed conversion ratio, or average weekly egg quality parameters. The 8 week average EW of eggs from the HOPN group had reduced EW relative to the other treatment groups (p = 0.0004). The 8-week average yolk color score (p < 0.0001) was greater in eggs from the HOPN group relative to the other treatments. Overall, the β-carotene (p < 0.006) and OA content (p < 0.0001) was greater in eggs from the HOPN group, with reduced saturated fats in eggs from the HOPN group relative to the other treatments. These results suggest that HOPN and/or OA may be a useful layer feed ingredient to enrich eggs, while significantly reducing egg size in older production hens.

Background: Resistance to foliar fungal diseases along with oleic acid trait, are important objectives of groundnut breeding. Among foliar fungal diseases, rust and Late Leaf Spot (LLS) cause significant economic loss and high oleic trait is preferred in industry that enhances economic values of crop. Methods: Morphological characterization of the 186-groundnut germplasm lines/genotypes for ten yield attributing traits and their significance of correlation was analyzed using SPSS ver. 19 software at 1% and 5% probability level of significance. Screening for LLS and rust diseases was done employing 10X SNP assay at ICRISAT, Hyderabad, India. Selected superior groundnut germplasm line(s) were screened for presence of FAD2B allele responsible for high oleic acid traits using allele specific marker. Result: Significant and positive correlation was found between dry weight and hundred pod weight (r=0.0.801) and harvest index (r=0.0.830). Molecular characterization along with morphological characterization identified highly diversified lines of groundnut. This study reports 78 foliar fungal disease resistant groundnut germplasm lines. Selected 11 groundnut germplasm lines represented resistance against LLS and rust diseases along with FAD2B allele for oleic acid trait.

Abstract As compared with normal-oleic peanut, high-oleic peanut proved to be heart-healthier, and had prolonged shelf life and extended seed longevity. However, there have concerns about the genetic diversity of present-day high-oleic peanut cultivars, which relied heavily on high-oleic donors with F435 type FAD2 mutations. In the study, a total of 104 high-oleic peanut cultivars/lines/mutants from main breeding teams in China were used to assess their genetic diversity with AhMITE markers. Of all the 31 cultivars tested, those from CTW team had the highest genetic variability. Again, of all the 73 lines studied, those from CTW team ranked first in genetic diversity. As compared with cultivars from CTW and C&Y teams, greater genetic diversity was detected in new lines of both teams, indicating that recent breeding efforts had resulted in improved genetic diversity in high-oleic peanut.
