Web1 de nov. de 2015 · Identifying putative haploids is a key issue in haploid breeding. DH technology in Brassicas and cereals, such as barley, maize, rice, rye and wheat, has been improved and used routinely in cultivar development, while in other food staples such as pulses and root crops the technology has not reached to the stage leading to its … Web1) frequency was observed to be 0.48% in this study (Table 1), which was consistent with earlier reports (0.03 to 0.61%) [7]. Albino plantlets were also observed during regeneration. The spontaneous chromosome doubling was reported in various species with varying frequencies such as barley (7 0-90%), wheat (2 5-70%) including rice (50-60%) [8].
