Of the 3 chemical treatments, viz. 5 mM ethyl methane sulfonate(EMS), 25 mM EMS and 15 mM sodium azide(NaN_3), only NaN_3 produced HO M_2 mutant plants. High oleate phenotype was initially identified by near infrared spectroscopy(NIRS) screening, and was further confirmed by gas spectrometry(GC) analysis. Sequence analysis showed that HO plant had a 448 G>A mutation in FAD2 A and a 441_442 insA mutation in FAD2 B, respectively. Although the direct use of high yielding and stress resistant cultivars/lines to induce quality mutations might be a judicious choice to accelerate breeding, our results showed that chemical mutagenesis could quickly create HO peanut materials and expand the genetic bases of HO peanuts.展开更多
