Genetic variability and association pattern among nutritional traits in recombinant inbred lines of groundnut (Arachis hypogaea L.)

Published on

Groundnut (Arachis hypogaea L.) is the world’s third most
important source of oil and fourth most important source
of vegetable protein. Oil content, protein content and fatty
acid composition (O/L ratio) are the most important quality
attributes of groundnut. A mapping population segregating
for these traits was evaluated for genetic variability and
correlation among the traits. The population exhibited
significant variation among the genotypes, seasons and
G x E interaction. Moderate magnitude of variability
followed by higher heritability was observed for most of
the quality traits. Negative correlation between oil and
protein content, oleic and linoleic acid indicated their
antagonistic nature. All the eight fatty acids were
correlated with each other either positively or negatively.
Superior RILs were identified for higher protein content,
oil content, oleic acid and O/L ratio from the population.
