【摘要】 吉亚四号是以Flandi为母本,以89-9为父本经杂交选育而成,具有高产、高纤、优质、抗倒伏、适应性广等特点。区域试验:平均每公顷原茎、长纤维和种子产量分别为6290.33kg、1308.01kg和672.43kg,分别比对照品种双亚5号增产12.72%、24.82%和12.58%。生产试验平均每公顷原茎、长纤维和种子产量分别为6309kg、1288.54kg和693.83kg,分别比对照品种双亚5号增产13.02%%、24.05%和16.68%。长麻率20.4%,全麻率29.11%,纤维强度27.3kg。更多还原

【Abstract】 Jiya No.4 was bred by cross of Flandi× 89-9.It is of high yield,high fibre content,superior fiber quality,lodging-resistance and high adaptation.The results of regional experiment showed the yield of stem,long fiber and seed was 6290.33kg/hm2,1308.01kg/hm2 and 672.43kg/hm2,an increase of 12.72%,24.82% and 12.58% respectively over check Shuangya No.5.The yield of stem,long fiber and seed was 6309kg/hm2,1288.54kg kg/hm2 and 693.83kg kg/hm2,an increase of 13.02% % 、 24.05% and 16.68% over check Shuangya No.5 in productional experiment.The long fiber content of Jiya No.4 is 20.4%,total fibre content is 29.11% and fibre strength is 27.3 kg.更多还原
