黑藜品种冀藜5号选育技术研究

Research on Breeding Technique of Black Chenopodium quinoa Variety Jili No.5

  • 摘要: 冀藜5号是利用剪穗套袋人工辅助杂交法,用秘鲁的安第斯奎宁藜麦与秘鲁黑藜杂交,经穗系选择、品种比较、区域适应性试验、多年多点生产鉴定及大面积示范选育出的生育期中等、矮秆的黑藜麦品种。该品种生育期中等,生育期115 d,株高160 cm,小穗数48个,穗粒质量45 g,千粒质量3.65 g,粗蛋白含量15.20%,粗脂肪含量4.50%,粗淀粉含量65.70%。一般旱地种植平均产量为2 626.10 kg/hm2,比对照品种冀藜1号增产264.77 kg/hm2,增幅11.21%。

     

    Abstract: Jili No.5 is a medium and dwarf variety of Chenopodium quinoa with medium growth period,which is bred by cutting ears and bagging artificial assisted hybridization,crossing Andes Quinine Chenopodium quinoa and Peru black Chenopodium qui‐noa,through ear line selection,variety comparison,regional adaptability test,multi-point production identification for many years and large-scale demonstration.The variety has a medium growth period of 115 days,a plant height of 160 cm,48 spikelets,a grain weight of 45 g per ear,a 1 000 grain weight of 3.65 g,a unit weight of 665 g,a crude protein content of 15.20%,a crude fat conten of 4.50%,and a crude starch content of 65.70%.The average yield of dry land planting is 2 626.10 kg/hm~2,which is 264.77 kg hm~2higher than the control variety Jizhi No.1,with an increase of 11.21%.
