An efficient genotype independent, in vitro regeneration system was developed for nine popular Indian wheat cultivars, three each of Triticum aestivum L. viz., CPAN1676, HD2329 and PBW343, Triticum durum Desf. viz., PDW215, PDW233 and WH896, and Triticum dicoccum Schrank. Schubl. viz., DDK1001, DDK1025 and DDK1029, by manipulating the concentration and time of exposure to the growth regulator, thidiazuron (TDZ). A total of 18 (for immature inflorescence and embryo explant) and six (for mature embryo explant) different combinations of growth regulators were tried for callusing and regeneration, respectively. Media combination with low concentration of TDZ (2.2 μM) in combination to auxin and/or cytokinin (depending upon culture stage), was found to be effective for immature and mature explants. Compact, nodular and highly embryogenic calli were obtained by using immature embryo, immature inflorescence and mature embryo explants, and regeneration frequency up to 25 shoots/explant with an overall 80% regeneration was achieved. Comparable regeneration frequency was achieved for mature embryo explants. No separate hormone combination for rooting was required and plantlets ready to transfer to soil could be obtained in a short period of 8–10 weeks. This protocol can be used for raising transgenic plants for functional genomics analysis of agronomically important traits in the three species of wheat.
