Identification of QTLs associated with oil content and mapping FAD2 genes and their relative contribution to oil quality in peanut (Arachis hypogaeaL.)

Table 5 Phenotypic value in percentage of the oil quality traits in RILs by genotypes of ahFAD2A and ahFAD2B genes in the S-population and the T-population

Quality traits	S-Population				T-population
	AABB (66)	AAbb (51)	aaBB (65)	aabb (60)	AABB (92)	aaBB (130)
Oleic acid (C18:1)	46.52	57.03	55.58	70.23	44.2	52.56
Linoleic acid (C18:2)	32.50	23.79	25.03	12.72	34.2	27.44
Oleic/linoleic acid ratio (OLR)	2.17	5.09	4.50	17.68	1.35	2.22

AA: wild A sub-genome allele for ahFAD2A gene in homozygous condition, aa: mutant A sub-genome allele for ahFAD2A gene in homozygous condition, Aa: ahFAD2A gene in heterozygous condition in A sub-genome, BB: wild B sub-genome allele for ahFAD2B gene in homozygous condition, bb: mutant B sub-genome allele for ahFAD2B gene in homozygous condition, Bb: ahFAD2B gene in heterozygous condition in B sub-genome. The number in parentheses is the number of RILs with that specific genotype.
