1、 棕色彩棉 汇报结构 彩棉 天然彩棉是利用基因改性技术培育出的棉花。即 对棉花植株植入不同的颜色基因，从而使棉桃在生长 过程中具有不同的颜色 棕、绿、灰、黄等。 棕色彩棉 红色彩棉 蓝色彩棉 绿色彩棉 研究背景 相较于传统白色陆地棉，彩棉的优点 以天然彩棉为原材料的棉织品无需漂染，不含残 留化学毒素，不褪色，松软、透气、穿着舒适，经济 价值高，并且在其棉织品的加工过程中免去漂白、染 色等工序，减少了衣物上对人体有害或容易造成皮肤 过敏的附着物，还可降低污水排放，适量避免对环境 的污染，具有绿色环保的特点，同时可减少能耗，降 低成本，提高产品附加值。 研究背景 彩棉织品 相较于传统白色陆地棉，彩
2、棉的劣势 与传统白色棉相比，彩色棉的主要劣势在于产量 低、品质差、色素遗传不稳定等。 研究背景 研究目的：对参试彩色棉品种的 主要产量及品质性状进行综合分 析，评定出相对优势种，为彩色 棉的种质选育、栽培和生产提供 一定的可能性参考。 研究目的 参评性状 本研究以新疆农一师农科所3#地所培育的14个来自新疆农 科院的彩棉品种（系）为材料，参评的主要性状有两类： 产量性状：籽棉产量（kg/hm2），皮棉产量（kg/hm2）， 霜前花率（%），衣分（%），生育期（d），株结铃数（个）， 单铃重（g），籽指（g）。 品质性状：纤维长度（mm），整齐度指数（%），断裂比 强度（cN/tex），伸长率（
3、%），马克隆值，纺纱均匀指数。 其中，品质性状送检于中国棉花研究所；产量性状自行称 测，采集实验数据。 研究内容 品种X1X2X3X4X5X6X7X8X9X10X11X12X13X14 PZ-127.884.128.18.94.4128.04291.21770.398.141.6128.05.65.29.2 PZ-230.185.729.36.84.2144.05128.52115.898.541.6129.05.95.69.8 PZ-328.785.330.77.13.9148.04313.41767.098.041.3127.05.45.210.1 PZ-428.184.828.16.74
