一种培育菊芋杂交种子获得菊芋杂交种植株和块茎的方法

Abstract

The invention relates to a method for cultivating jerusalem artichoke hybrid seeds and obtaining jerusalem artichoke planting hybrid strains and tuber. The method comprises the following steps that: the jerusalem artichoke hybrid seeds are organized to be cultivated and jerusalem artichoke seedlings are obtained. The method of the invention overcomes the defects that the jerusalem artichoke hybrid seeds have low seed setting rate, are not easy to sprout at conventional conditions, are difficult to obtain effective individual plants, the appraisal cycle of the method applied to the farmland from the seeds to obtaining the hybrid tubers which is affected by the growth period is long. The method of the invention can effectively keep the jerusalem artichoke hybrid mutation, greatly shortens the cycle from the mutation into the farmland appraisal, can provide quite many optional mutation sources for jerusalem artichoke hybridization, speed up the selection process of hybrid breeding, and have good application prospect in jerusalem artichoke hybridization.
本发明涉及一种繁殖菊芋杂交种子获得菊芋杂交种植株和块茎的方法。该方法包括如下步骤:组织培养菊芋杂交种子获得菊芋实生苗。本发明方法克服了菊芋杂交种子结实率低、常规条件下不易发芽、难以获得有效植株个体、且由于受生育期的影响从种子到获得杂交种块茎应用于大田鉴定周期长的缺陷。本发明方法可有效的保留菊芋杂交变异,极大缩短变异进入大田鉴定的周期,可为菊芋杂交育种提供较多的可供选择的变异来源,加速杂交育种的选育进程,在菊芋杂交育种中具有良好的应用前景。
