“六五”期间我国高粱品种资源的研究已从收集整理和农艺性状鉴定开始转向以特性鉴定为主的新阶段。我国拥有高粱地方品种约万余份,占世界现保存高粱种质总数的三分之一以上。已进行的14692项次特性鉴定,划分了抗性等级,筛选出部分抗早、耐瘠材料。对营养品质及综合利用特性也做了初步鉴定。“六五”期间外引高粱资源7—8千份。除直接利用新引不育系发展了杂交高粱的生产外。还在外引资源中发现了一些抗高粱蚜,抗丝黑穗病的材料。
During the period of the Sixth Five-Year Plan, the research on sorghum variety resources in our country has shifted from collecting and sorting and identification of agronomic traits to a new stage characterized mainly by characterization. Our country owns more than ten thousand varieties of local sorghum, accounting for more than one third of the total number of the world’s existing sorghum varieties. Has carried out 14692 times characterization, divided the resistance level, selected part of anti-early, barren material. On the nutritional quality and comprehensive utilization characteristics also made a preliminary identification. During the “Sixth Five-Year” period, 7-8 thousand sorghum resources were introduced. In addition to direct use of new CMS lines to develop hybrid sorghum production. Some foreign sorghum aphids and anti-head smut were also found in the external sources.
