大田种植的810株杂交水稻汕优6号组织培养的再生植株均能抽穗结实。再生植株在大田中总叶片减少,成熟期提早,植株变矮,经济性状多数变劣。但也有少数优良性状出现,这可能是现行的组织培养过程中环境引起的生理性变异。 为了建立禾谷类的无性繁殖系,有必要对组织培养技术进行更深入的研究和改进。 810 hybrid rice planted in field was regenerated from tissue culture of Shanyou 6. Regenerated plants in the field to reduce the total leaves, mature earlier, shorter plants, most of the deterioration of economic traits. However, a few fine traits appeared, which may be the physiological variation caused by the environment during the current tissue culture. In order to establish clonal lines of cereals, it is necessary to conduct further research and improvement of tissue culture techniques.
