Abstract
A successful regeneration system is presented for elite cultivars in barley and wheat based on nodes. Nodal explants were excised from in vitro and ex vitro grown plants. A combination of 8.28 μM 4-amino-3,5,6-trichloropicolinic acid and 4.54 μM to 22.71 μm thidiazuron (TDZ) used in MS-based medium containing 60 g l−1 maltose favoured induction of clumps of multiple shoots/buds with or without callus formation in the primary cultures. Within 8–10 weeks upon further subcultures, the proliferation into callus with rapid and continuously forming adventitious buds containing clusters of meristemoids, termed meristematic bulk tissue (MBT) was obtained. Lowering the levels of growth regulators resulted in redifferentiation of shoots, which elongated, rooted, developed into morphologically normal plants and set seeds normally. With a frequency ranging between 37 and 82% the nodes raised from in vitro grown plants were proliferated into MBT independent of TDZ concentration, cultivar and species. The average number of shoots per responding node in different cultivars was 7–15 in barley and 1–6 in wheat after 12–14 weeks. Nodes from greenhouse grown plants mainly responded for callus formation with poor development of MBT.
