远棉一号是由河北省石家庄地区农科所与中国科学院遗传研究所合作,采用棉属种间杂交,杂交幼胚离体培养、试管内染色体加倍等高新技术与常规育种相结合,经近20年时间培育而成,其组合为:冀棉8号×{[(科遗2号×皖紫)F_1×(长德184+Δ9+陕401)]×黑山棉1号}。 一、产量高:经过几年计产试验,霜前亩产皮棉82.6—99.5千克,比对照增产3.2～11.6％。1991年参加了中国、美国、西班牙、叙利亚国际间种质资源评估试验,在国内石家庄试点,平均亩产皮棉69.0千克、比国外产量最高的参试品种美86—16还增产8.2％。 在示范过程中也充分体现了它的高产和抗逆性强,如威县1991年在旱薄地试种3亩,平均亩产皮
Yuanmou 1 is a collaboration between the Institute of Genetics and the Institute of Genetics, Chinese Academy of Sciences, Shijiazhuang, Hebei Province, which uses the hybridization of cotton genus, the in vitro culture of hybrid embryos, doubling of chromosomes in vitro and other conventional techniques. 20 years of cultivation from the combination of: Jimian 8 × {[Keji 2 × Wan purple) F_1 × (Changde 184 + Δ9 + Shaan 401)] × Heishan Cotton 1}. First, the high yield: After several years of production test, before frost 82.6-99.5 kg per mu lint, an increase of 3.2 to 11.6% over the control. In 1991, he participated in international germplasm resources assessment tests conducted in China, the United States, Spain and Syria. In Shijiazhuang, China, he experimented with an average of 69.0 kg of lint per mu, an 8.2% increase over the U.S. 86-16 with the highest yield in the United States. In the demonstration process also fully reflects its high yield and resistance to strong, such as Wei County in dry land in 3 acres planted in 1991, the average per mu hides
