Genetic analysis of oleic acid and linoleic acid content in relation to oil quality in groundnut

Abstract

The present study was conducted to estimate the heritability as well as relationship of oleic acid and linoleic acid with oil quality 
parameters among the backcross progenies in BC1F4 and BC1F5 generation of groundnut. The linoleic acid, oleic to linoleic acid 
ratio and polyunsaturated to saturated fatty acid ratio exhibited high PCV and PCV estimates as well as high heritability coupled 
with high genetic advance as per cent of mean in both generations. The strong negative relationship between oleic acid and 
linoleic acid was observed in virtual elimination of linoleic acid from seed lipids is accompanied by an equivalent increase in the 
content of oleic acid, the proportion of other fatty acids remained unchanged, indicate that the mutation blocks the desaturation of 
oleic to linoleic acid in high oleate advance backcross progenies.
