Abstract

Near infrared reflectance spectroscopy (NIRS) analysis of peanut kernels of different grades by mainly using advanced breeding lines derived from intersectional crosses in 2 experiments gave similar results, showing remarkable inter-grade variation in oil content of a specific entry. The effects of genotype on qualitative attributes proved to be predominant. No significant differences in protein content, oleic acid/linoleic acid content in total fatty acids, and oleic acid/linoleic acid ratio were detected among the No. 1, No. 2 and No. 3 grade peanut kernels of a given peanut genotype.
