PRELIMINARY CHARACTERIZATION OF SOME PHYSIOLOGICALLY IMPORTANT MUTANTS IN BRASSICA /UNCEA L. COSS. & CZERN. VARIETY RLM 198

Published on

This is a preliminary report of some ~S induced morphological mutants in Brassiea
juneea variety RLM 198. In this paper we report mutants in which the angle formed
by the primary branches to the main shoot was 50"10 less than control plants. Such
mutants can be used for obtaining higher plant population in the field which is
not possible with existing higher yielding cultivars. We report some 'Early flowering'
mutants in which flowering was advanced by 20 days increasing the effective seed
filling duration. Total seed weight per siliquae increased by 78"10 over control. We
also report 'waxy' mutants in which SEM studies revealed thick waxy deposits on
leaf surface and some variants that show branching from the base.
