Inheritance of low erucic acid in Indian mustard [Brassica juncea (L.) Czern. and Coss.]

Published on

Genetics of erucic acid content was studied using six
generations viz., P1, P2, F1, F2, B1 and B2 derived from the
crosses, Varuna × LES-39 and Varuna × LES-1-27.The trait
high erucic acid content was partially dominant over low
erucic acid content in both the crosses. In both the crosses,
adequacy of additive – dominance model suggested
absence of non-allelic interactions.The study revealed that
selection for low erucic acid would result in isolation of
plants with high oleic and linoleic acids and hence, it should
be possible to develop high oleic acid lines having low
erucic acid content in mustard.
