谷子化学杀雄剂筛选

关键词：
谷子;化学杀雄剂;筛选
摘  要：
为了丰富谷子杂交育种手段、提升杂交育种效率,在谷子雌雄蕊原基分化期,用5种化学试剂对不同品种谷子穗部进行杀雄处理,综合考虑处理后植株套袋自交和饱和授粉结实情况,筛选出草甘膦铵盐为适宜的谷子化学杀雄剂,并对其适宜浓度进一步筛选,得出大同34号和大同27号的最佳施用浓度为3.75～5.00mg/L,大白谷的最佳施用浓度为10.00mg/L,品种不同,最佳施用浓度存在差异。

摘  要：
In order to enrich the cross-breeding methods of millet and improve the efficiency of cross-breeding, five kinds of chemical reagents were used to kill the male of different varieties of millet at the primordium differentiation stage of pistil and stamen of millet. Based on the fruiting of the treated millet after self-cross and saturated pollination, glyphosate ammonium salt was selected as the suitable chemical male killing agent for millet, and the suitable concentration of glyphosate ammonium salt was further screened. The results showed that the optimum application concentration of Datong 34 and Datong 27 were 3.75-5.00 mg/L, and that of Dabaigu was 10.00 mg/L. The best application concentration was different when the varieties were different.
