【摘要】 目的利用张家口农业科学院科研育种优势,培育适宜冀北地区种子的苦荞新品种,填补冀北地区无自主苦荞新品种的空白,进行苦荞品种的选育。方法冀苦荞1号是张家口市农业科学院从湖南引进的一个当地品种,是经观察鉴定、品系比较、区域联合试验、生产鉴定试验和大面积示范筛选成的一个高产早熟型苦荞新品种。结果该品种生育期88 d,千粒重18.4 g,株高111.7 cm;平均产量2 740.5 kg·hm^-2,比北方地区主栽的苦荞黑丰1号增产745.7 kg·hm^-2,增幅37.4%;比日本品种本地大粒荞增产1 305 kg·hm^-2,增幅90.8%;蛋白质含量11.32%,比黑丰1号高2.29%;脂肪含量1.59%,比对照低0.95%。结论该品种产量高,品质优,抗倒伏力强,抗旱耐瘠性强,抗落粒性强,适应性广,适宜冀北地区种植。更多还原

【Abstract】 Objective Making use of the advantages of scientific research and breeding of Zhangjiakou Academy of Agricultural Sciences,cultivate new tartary buckwheat varieties suitable for seeds in northern Hebei and fill the blank of new tartary buckwheat varieties in northern Hebei,and the breeding of tartary buckwheat varieties was carried out.Methods Jikuqiao No.1 is a local variety introduced from Hunan by Zhangjiakou Academy of Agricultural Sciences.It is a new high-yield and early-maturing buckwheat variety selected by observation and identification,strain comparison,regional joint test,production identification test and large-scale demonstration.Results The growth period of this variety was 88 days,1000 grain weight was 18.4 g and plant height was 111.7 cm.The average yield was 2740.5 kg/hm~2,745.7 kg/hm~2 and 37.4% more than the local variety Heifeng No.1 and 1 305 kg/hm~2 and 90.8% more than the Japanese variety Daliqiao;the protein content of this variety was 11.32%,2.29% higher than that of the control Heifeng No.1,and the fat content was 1.59%,0.95% lower than the control.Conclusion This variety has high yield,excellent quality,strong lodging resistance,strong drought resistance and barren resistance,strong resistance to grain falling,and wide adaptability.It is suitable for planting in North Hebei.更多还原
