NIRS Calibration Models Predictive of Oleic, Linoleic and Palmitic Acid Content in Sun-dried Bulk Peanut Seed Samples
Near Infrared Spectroscopy (NIRS) analyzing technique has been usedcommonly in plant breeding.It is also very useful to improve efficiency of peanut quality breeding. NIRS calibration models for sun-dried bulk samples were established for prediction of oleic, linoleic and palmitic acid contents, using peanut germplasm accessions of diverse origin, including large and small seeded genotypes with various seed coat colors. The optimized spectrum pretreatment method was first derivative plus vector normalization. The spectrum range, rank, R2 and RMSECV for oleic acid were 8717.1-5446.3 cm-1, 9, 89.16 and 2.62; these values were 9666-5785.7 cm-1, 990.85 and 2.00 for linoleic acid; they were 8717.1-5446.3 cm-1, 879.21 and 0.525 for palmitic acid, respectively. The models may be used in peanut quality breeding programs.
