摘要: For the high frequency selection of salt-tolerant doubled haploids (DHs) using rice anther culture, efficiency culture was investigated with different genotype, media condition and NaCl concentrations. The six F1 hybrids obtained by backcross or three-way cross between indica japonica differed in salt tolerance. efficiencies callus induction plant regeneration decreased concentration tolerance donor variety, those japonicas were higher than indicas. percentages Gyehwa 5 (japonica, tolerant) IR61633-B-2-2-1 sensitive) 21.1 13.5% on agar medium containing 0.3% NaCl, respectively. derived from floating liquid less that solid medium. In four hybrids, frequencies DHs 21.4 8.9% control, could be selected (0.3% NaCl) combinations crossed as third parent.
