【摘要】 【目的】选育出适合多元化种植模式的早熟棉花新品种，为粮食生产与棉花产业的协调发展提供新的思路。【方法】选用邯郸市农业科学院自育的棉花新品系HS601为母本和转基因抗虫棉邯685为父本杂交，经南繁北育，定向选择，成功培育出早熟棉新品种邯3206。【结果】早熟棉新品种邯3206于2019—2020年参加黄河流域棉区早熟组棉花品种区域试验，2年平均子棉、皮棉和霜前皮棉产量分别为3 547.5 kg/hm~2、1 449.0 kg/hm~2和1 327.5 kg/hm~2,分别比对照品种中棉所50增产7.7%、10.2%和9.6%。该品种生育期98 d,株型较紧凑，茎秆较粗壮。邯3206于2021年通过河北省品种委员会审定(冀审棉20219001),2022年通过国家品种委员会审定(国审棉20220028)。【结论】邯3206生育期短，在黄河流域棉区与蔬菜作物(甘蓝、西蓝花、大蒜)进行两熟制多元化配套栽培可取得较好经济效益。更多还原

【Abstract】 【Objective】 New early-maturing cotton varieties suitable for diversified planting modes were bred to provide the new ideas for the coordinated development of grain production and cotton industry. 【Method】 Han 3206, a new early-maturing cotton variety, was bred successfully by using the new cotton line HS601(bred by Handan Academy of Agricultural sciences) as female parent and the transgenic insect resistant cotton Han 685 as male parent through the south propagation and north breed and directional selection.【Result】 The new early-maturing cotton variety Han 3206 was participated in the regional trial of early-maturing cotton varieties in the Yellow River Basin during 2019-2020. The two-year average yields of seed cotton, lint cotton, and pre-frost lint cotton were 3 547.5 kg/hm~2, 1 449.0 kg/hm~2 and 1 327.5 kg/hm~2 respectively, increasing by 7.7%, 10.2%, and 9.6% compared to the control variety Zhongmiansuo 50. Han 3206 had a growth period of 98 days, a compact plant type, and a thick stem. It was approved by Hebei Variety Approval Committee in 2021(Approval number: Jishenmian 20219001) and approved by National Variety Approval Committee in 2022(Approval number: Guoshenmian 20220028). 【Conclusion】Han 3206 with short growth period and vegetable(cabbage, broccoli and garlic)could be obtained better economic benefit by diversified supporting cultivation of double cropping system in the Yellow River Basin.更多还原
