【摘要】 中棉属于亚洲棉(C.arboreum L.)的族系。1982～1985年,对200个品种进行田间调查和纤维、棉籽仁测试分析。结果是:中棉生育期100天左右,变幅在97～103天。衣分平均31.01%,变幅18.96～40.47%。2.5%跨距长度(Span Length)平均20.24mm,变幅16.2～24.7mm。纤维比强度(g/tex)平均22.27,变幅11～31.0之间。纤维细度麦克隆值(Micronaire)平均7.45,变幅5.5～9.3。通过鉴定获得了植物学性状不同的6个新类型和4个抗黄萎病材料;中棉粗蛋白质含量较高,变幅32.4～43.6%。脂肪酸的食用品质较好:其中油酸 C18∶1,平均含21.9～42.5%,亚油酸(C18∶2)平均含34.8～55.4%。更多还原

【Abstract】 Gossypium arboreum race sinense is one of the six geographical racesof G.arboreum L.Two hundred varieties of this race were studied during1982～1985.These varieties are early maturing,averaging 100 daysfrom seedling emergence to boll opening,varying from 97 to 103 days.Their lint percentages vary from 18.96% to 40.47%,averaging 31.01%2.5% span fiber length varies from 16.2 to 24.7 mm,averaging 20.24mm;fiber strength varies from 11～31.0,averaging 22.27g/tex;micro-naire varies from 9.3 to 5.5,averaging 7.45.Six new types with specialbotanical characteristics and four germplasm accessions resistant to Ver-ticillum wilt were identified in this study.The nutrient qualities ofthe seed of the race are promising,containing 32.4～43.6%,21.9～42.5%and 34.8～55.4% of crude proteins,fatty acids C_18:1and C_18:2respec-tively.更多还原
