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.

Low Levels

Abstract Florunner peanut seeds contained five trypsin isoinhibitors. Amino acid profiles of the trypsin inhibitors fraction showed high levels of aspartic acid, half-cystine and serine and low levels of histidine and tyrosine. The molecular weight of the inhibitor was 8.3 KDa. The presence of multiforms of this inhibitor, its low molecular weight and the high amount of half-cystine indicate that peanut trypsin inhibitor is of the Bowman-Birk type.

Abstract Field experiments were conducted at nine locations in Texas and Georgia in 2005 and 2006 to evaluate peanut tolerance to lactofen. Lactofen at 220 g ai/ha plus crop oil concentrate was applied to peanut at 6 leaf (lf), 6 lf followed by (fb) 15 days after the initial treatment (DAIT), 15 DAIT alone, 6 lf fb 30 DAIT, 30 DAIT alone, 6 lf fb 45 DAIT, 45 DAIT alone, 6 lf fb 60 DAIT, and 60 DAIT alone in weed-free plots. Lactofen caused visible leaf bronzing at all locations. Yield loss was observed when applications were made 45 DAIT, a timing that would correspond to plants in the R5 (beginning seed) to R6 (full seed) stage of growth. At all locations except the Texas High Plains, this application timing was within the 90 d preharvest interval. Growers who apply lactofen early in the peanut growing season to small weeds should have confidence that yields will not be negatively impacted despite dramatic above-ground injury symptoms; however, applications made later in the season, during seed fill, may adversely affect yield.

Significant Injury

Abstract Lesser cornstalk borer, Elasmopalpus lignosellus (Zeller) (Lepidoptera: Pyralidae), larval injury to the root-hypocotyl region of greenhouse-reared ‘Florunner’ peanut, Arachis hypogaea L., plants was investigated by determining the size and distribution of feeding sites. The percent injury to periderm, cortex, phloem, and xylem tissues also was estimated. Tissue loss due to insect feeding was measured for only the most prominent of several wound sites on each stem axis. Percent injury to principal tissues was estimated by planimetric methods. The lesser cornstalk borer caused significant injury to the periderm, cortex, and the phloem on mainstems of peanut plants. Mean percent injury was 31.67% for the periderm and cortex, 16.78% for phloem, and only 0.19% for the xylem. Approximately 91% of all feeding sites occurred on the mainstem or were contiguous with the mainstem and a branch. The frequently of plants with feeding sites declined linearly with increasing number of sites. These data support the hypothesis that root growth declines with increasing larval injury to phloem and xylem (food and water conducting tissues, respectively) in the root-hypocotyl region.
