通过区试,选育出早熟、丰产、纤维品质优良、抗病性能强的陆地棉品种。 一、基本情况 1、参试品种(系)为94—4、97—2、对照种为岱字80。 2、棉花行距50厘米,株距25厘米,播期为4月15～18日。 二、试验结果及分析 1、94—4。生育期为114天,较对照岱字80晚熟3天。株高94.8厘米,第一果枝节位5.1节,果枝数15个,单株成铃11.6个,单铃重5.6克,衣分最高41.29％,衣指7.2克,籽指10.6克。经农业部棉花品质检验测试中心纤维物理性测定,主体长度29.9毫米,强力29.4特克斯,马克隆值4.9,整齐度84.5％,纺纱均匀指数136,均优于对照。但伸长率、反射率、黄度等指标不及岱字80。在区试中表现适应性强,品质、产量上与对照相比有很大优势。4个点平均每666.7米~2产籽棉307.95公斤,皮棉较对照岱字80增产20.28％,名列第一。
Through the district test, bred a variety of upland cotton, high yield, good fiber quality, strong resistance to disease. First, the basic situation 1, the test varieties (lines) 94-4,97-2, the control type Dai word 80. 2, cotton spacing 50 cm, spacing 25 cm, sowing date of April 15 to 18. Second, the test results and analysis 1,94-4. Growth period of 114 days, 80 days later than the control Dai Dai 3 days. Plant height 94.8 cm, the first fruiting branch node 5.1, fruit branch number 15, boll per plant 11.6, boll weight 5.6 grams, the highest 41.29%, the index finger 7.2 grams, the index finger 10.6 grams. The Ministry of Agriculture cotton quality testing center fiber physical determination, the main length of 29.9 mm, strong 29.4 tex, micronaire value of 4.9, uniformity of 84.5%, spinning uniformity index 136, were better than the control. However, the elongation, reflectivity, yellowness and other indicators less than Dai word 80. In the district test showed strong adaptability, quality, yield compared with the control has a great advantage. 4 points average per 666.7 meters ~ 2 seed cotton 307.95 kg, lint 80% increase compared with the control Dai 20.28%, ranked first.
