苏联棉花品种斯—1470,在我站已试种3年,现介绍其特性如下: 一、品种来源及引进时间 斯—1470系苏联中央育种站斯卡那什用杂交种斯—450与中熟种18819杂交选育而成。在原产地其主要特徵是早熟、铃大、绒长、植株紧凑。1955年由苏联专家提托夫教授介绍,分别在石河子、车排子及吐鲁番等地试种。1956年,引入我站原始材料圃试种观察。1958年由自治区农科所发给原种,参加国家区域品种比较试验。 二、试种情况 (1)品种特性:该品种植株紧湊,发叶性较强,叶面肥大,叶裂浅,与18819品种相近似。铃圆而带尖,4—5室,铃面不光滑,呈浓绿色。雌蕊柱头伸出,雄蕊短,易於自花授粉。栽培中如浇水过多,较不易疯长。幼苗生长比108—埃夫快,现蕾以後生长比108—埃夫慢。根据1957年记载,斯—1470与临近对照相比,该品种3天生长1.03公分,而108—埃夫仅生长0.83公分。现蕾后,该品种5天生长3.64公分,而108—埃夫生长6.41公分。出苗到吐絮的生长期比108—埃夫早2—6天。其他方面,据历年的田间调查,也有一定的优势。
Soviet Union cotton varieties Sri Lanka -1470, I have been in the trial of three years, is now introduced its characteristics are as follows: First, the source of species and the introduction of time Sri Lanka -1470 Department of Soviet Union Central Breeding Station Scarrian hybrid with Sri Lanka -450 and cooked 18819 hybrid breeding. Its main features in the country of origin are precocious, large bells, long cashmere, and compact plants. Introduced by Professor Titov in 1955 by the Soviet Union, they were planted in Shihezi, Chepaizi and Turpan, respectively. In 1956, the introduction of raw materials in our station nursery plant observation. In 1958 by the autonomous region of agriculture sent to the original species, to participate in the national regional comparative test. Second, the test situation (1) Variety characteristics: The varieties of plants compact, strong leaves, foliar hypertrophy, leaf split shallow, and 18819 similar varieties. Bell round and pointed, 4-5 room, bell surface is not smooth, was dark green. Pistil stigma extending, stamens short, easy to self-pollinate. Cultivation, such as watering too much, not easy to crazy long. Seedlings grow faster than 108-ef and grow slower than 108-efu after budding. According to the 1957 record, Si-1470 grew 1.03 cm in 3 days compared to the adjacent controls, while 108-Eff grew only 0.83 cm. After budding, the breed grew 3.64 cm in 5 days, while the 108-elv grew 6.41 cm. Emergence to the growth of boll opening than 108-eve 2-6 days earlier. Elsewhere, according to the field surveys over the years, there are certain advantages.
