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

摘要

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.
