克劳茨基棉(G.klotschianum D_(3-k))组织培养虽早已有报道,但至今进展不大.为了有效地利用克劳茨基棉的优良性状,加速生物技术在棉花品种改良上的应用,我们以克劳茨基棉的花药为外植体,进行了广泛的探讨.现已通过胚胎发生途径获得了再生植株,该结果国内外还未见报道.1 材料与方法 Although the tissue culture of G. klotschianum D_ (3-k) has long been reported, little progress has been made so far. In order to effectively utilize the excellent traits of klozit cotton, biotechnology is accelerated in cotton varieties improvement Of the application, we use klavitzian cotton anther as explants, has been widely discussed.Now we have obtained through the embryogenesis of regenerated plants, the results have not been reported at home and abroad.1 Materials and methods
