INTERSPECIFIC HYBRIDIZATION BETWEEN BRASSICA /UNCEA (L.) CZERN & COSS AND BRASSICA HIRTA MOENCH.

Published on

An interspecific hybrid between B. jultcea and B. hirta was produced. Neither hormonal
treatment nor embryo culture was necessary. Morphological features of the trigenomic
(ABS) hybrid resembled the female parent Varuna more doselythan B.
hirta. Chromosome
pairing at MI was 4.06 univalents, 12.31 bivalents and 0.44 trivalents per cell. High fertility
of the Fl hybrid indicated the possibility of transferring desirable traits of B.
hirta to the
elite cultivars of Indian mustard.
  

Keywords: Brassica juncea, Brassica hirta, interspecific hybrid.
