芥蓝游离小孢子培养技术优化及其在育种中的应用OA北大核心CSTPCD
Optimization and Application in Breeding of Isolated Microspore Culture Technology in Chinese Kale
以16个芥蓝品种(F1)为供体材料,比较分析了优化花蕾的消毒、小孢子的游离释放以及过滤等环节对芥蓝游离小孢子培养效果的影响.结果表明,16份参试芥蓝供体材料都具有胚胎发生能力,并全部获得了不同类型的再生植株,实现了较大规模、批量地获得芥蓝双单倍体(DH).经田间综合评价筛选,应用DH系育成了不同熟性的芥蓝一代杂种20M4芥蓝、21M2芥蓝和22M11芥蓝.
Taking 16 Chinese kale F1 hybrids as donor material,this paper compared and analyzed the effects of optimized buds disinfection,isolated microspore release and filtering on culture of Chinese kale free microspore.The results indicated that the 16 tested Chinese kale donor materials all had embryogenesis capability,and obtained regenerated plants of different types.Thus,a larger-scale and large quantities doubled haploid(DH)of Chinese kale were obtained.Through comprehensive evaluation and screening in the field,these DH lines by isolated microspore culture technology of Chinese kale were used in breeding,and 3 new Chinese kale F1 hybrids'20M4 Jielan''21M2 Jielan''22M11 Jielan'with different maturity were bred.
