Evaluation of doubled haploid culture conditions and regeneration of an indica rice hybrid

Published on

A study was undertaken to develop an effective protocol to
generate doubled haploid plants from a proprietary Mahyco
hybrid MRP5401. A total of 20,300 anthers were plated on
four different DH media (basal N6 + phytohormones) and
obtained a callus induction success rate of 1.52%, of which
0.48% developed into green plants. A total of 232 lines were
obtained of which, 98 lines showed homozygosity in DH2-
3 generations. Well established DH lines from MRP5401 in
DH3 generation had early flowering and yield gain.
