【摘要】 从胡麻主产区引进19个新育成的品种(系),2005年进行预备试验,综合其产量、农艺性状和抗病性,从中筛选出晋亚8号、8858、陇亚9号、97047、0144(甘肃)、91-197-8和3号胡麻7个表现较好的品种(系);2006年进行播种量试验。结果表明各引进胡麻品种(系)的产量在总体上都比作为对照的青海当地品种的产量高;晋亚8号、97047和陇亚9号是表现最好的3个品种,其适宜播种量为375~450万粒/hm2,具体为:晋亚8号和97047为375~450万粒/hm2,陇亚9号为375万粒/hm2左右。更多还原

【Abstract】 Nineteen new oil flax cultivars from China’s major oil flax producing areas were introduced into Qinghai Province,and preparatory study was made in 2005,from which 7 comparatively better cultivars were selected by considering their yield,agronomic traits and resistance.These 7 cultivars were Jinya No.8,8858,Longya No.9,97047,0144(Gansu),91-197-8 and Oil Flax No.3.Then the suitable seeding quantity of them was studied in 2006.The results showed that the yield of all the introduced cultivars was higher than the local cultivar,Jinya No.8,97047 and Longya No.9 were the three best of all the introduced cultivars on the whole,and the suitable seeding quantity were from 3,750,000 to 4,500,000 seeds per hm2.Specifically,the suitable seeding quantity of Jinya No.8 and 97047 were from 3,750,000 to 4,500,000 seeds per hm2;the suitable seeding quantity of Longya No.9 were about 3,750,000 seeds per hm2.更多还原
