【摘要】 试验了移栽水稻组织培养再生植株的方法,采用了“冰镇”,“水培”等炼苗、保苗措施,移栽的再生植株顺利完成一个生长周期,产生种子。获得的种子在第二年播种,进行 D₂代分析,发现一些性状变异.但是,在存活并完成生长期的植株中,遗传的变异幅度已较稳定。通过组培进行变异选育,作为一种方法,在水稻育种上具有重大意义。更多还原

【Abstract】 The method of transplanting the regenerated rice plantlets from tissue culture was test-ed.Using the treatment of“cooling”and“water-culture”,the plantlets finished theirgrowth cycle and yeilded seeds.The seeds were sowed in the next year.Genetic analysis in the D₂ generation wasmade,as a result some variations were found.But the variation range tended to be steady inthe plants of D₂ generation which finished their growth cycle.As a method to select seedlings according to variation through tissue culture,it is ofgreat importance in rice breeding.更多还原
