The experiment was
designed to determine erraticism among 188 Indian mustard genotypes based on
various biochemical characteristics such as palmitic, oleic, linoleic,
linolenic, and erucic acids, as well as oil composition.

The presence of a
significant amount of variation across selected Indian mustard genotypes was
determined by analysis of variance, implying improved prospects for their
improvement. Oleic acid has the highest genotypic and phenotypic coefficient of
variation, followed by erucic and palmitic acids. Heritability and genetic
advancement were determined by erucic, oleic, palmitic, linoleic, and linolenic
acids. Erucic acid has a strong negative association with palmitic, oleic,
linoleic, and linolenic acids. Palmitic acid had the most positive direct
effect on erucic acid in both genotypic and phenotypic path coefficient
studies, while linoleic, oleic, linolenic acids, and oil content had the
highest negative direct effect on erucic acid. The genotypes were clustered
into eighteen different groups using genetic deviation and Euclidean distance
clustering. Erucic acid was found to be low in 9 genotypes, moderate in 57
genotypes, and higher in 122 genotypes when all biochemical strictures were
examined. During a group analysis of qualitative indicators, a severe inter
cluster gap between cluster 18 (Karishma) and cluster 12 was discovered (Maya).
As a result, these genotypes could be used as parentages in Indian mustard
breeding to improve a variety of qualitative indices.
