今年4月,中国科学院植物研究所北京植物园在北京召开了“葡萄品种选育的研究”专题第一次会议,讨论并制定了“葡萄杂交育种程序(草案)”。根据这个草案,从杂交到决选出预备新品种,在一般情况下,需时15至17年。会上对何时开始繁殖优良单株,对复选出来的优良单株和进行比较试验时观察测定的项目等问题,展开了热烈的争论,这些问题,关系到育种年代的长短,杂种苗各种经济性状的稳定程度,以及观察测定所需工作量的多少,是值得重视和继续探讨的问题。本文根据讨论结果,加以整理,供各地葡萄育种工作者的参考,并请提出修改补充的意见。
In April this year, the First Botanical Garden of CAS Beijing Institute of Botany held the first meeting of “Research on Breeding of Grape Varieties” in Beijing and discussed and formulated the “Grape Hybridization Breeding Program (draft)”. According to this draft, from hybridization to the final selection of new varieties of preparation, under normal circumstances, takes 15 to 17 years. At the meeting, when to start breeding fine single plant, the check out of the outstanding single plant and the comparative test observation of the project and other issues, launched a heated debate, these issues related to the breeding age, hybrid seedlings The stability of various economic traits, as well as the amount of work required to observe the measurement, are issues that deserve attention and continue to be explored. This article based on the results of the discussion, be collated for reference grape grazing workers around the country, and please propose amendments to supplement the views.
