快育66是以含有海岛棉、陆地棉、野生瑟伯氏血缘以及转胁抗棉铃虫基因的高抗棉铃虫品种GK12为母本，以丰产潜力大、适应性强的冀棉8号01．698为父本，二者在温室内杂交，利用温室加代与大田选择相结合的1a3代棉花快速育种技术、以选育“优异株型”为突破1：7的选择方法，通过温室加代、自交纯合及田间鉴定选择，选育出的集高产、稳产、高效、广适于一体的转基因棉花新品种。该品种在2007～2009年河北省冀中南转基因常规棉品种区域试验中，皮棉、霜前皮棉产量分别为l518．0kg／hm2和1405．5kg／hm2，其中霜前皮棉较对照增产幅度达极显著水平；在2010年河北省冀中南转基因常规棉品种生产试验中，8点次全部增产，皮棉、霜前皮棉产量分别为1401．0kg／hm2和1314．0kg／hm2，均居参试品种第l位，分别较对照冀棉958增产7．7％和10．5％。该品种抗病性强（高抗枯萎，抗黄萎病），纤维品质综合配套（主体长度29．0mm，整齐度84．9％，比强度28．3cN／tex，马克隆值5．3），管理省工，综合表现突出。
快育66是以含有海島棉、陸地棉、野生瑟伯氏血緣以及轉脅抗棉鈴蟲基因的高抗棉鈴蟲品種GK12為母本，以豐產潛力大、適應性彊的冀棉8號01．698為父本，二者在溫室內雜交，利用溫室加代與大田選擇相結閤的1a3代棉花快速育種技術、以選育“優異株型”為突破1：7的選擇方法，通過溫室加代、自交純閤及田間鑒定選擇，選育齣的集高產、穩產、高效、廣適于一體的轉基因棉花新品種。該品種在2007～2009年河北省冀中南轉基因常規棉品種區域試驗中，皮棉、霜前皮棉產量分彆為l518．0kg／hm2和1405．5kg／hm2，其中霜前皮棉較對照增產幅度達極顯著水平；在2010年河北省冀中南轉基因常規棉品種生產試驗中，8點次全部增產，皮棉、霜前皮棉產量分彆為1401．0kg／hm2和1314．0kg／hm2，均居參試品種第l位，分彆較對照冀棉958增產7．7％和10．5％。該品種抗病性彊（高抗枯萎，抗黃萎病），纖維品質綜閤配套（主體長度29．0mm，整齊度84．9％，比彊度28．3cN／tex，馬剋隆值5．3），管理省工，綜閤錶現突齣。

The new cotton variety Kuaiyu 66 was developed by crossing between Bt transgenic variety GK12 (female parent) which was bred using G. hirsutum, G. barbadense, G. thurberi, and wild Thurber's material, with resistance to bollworm, and high-yield potential, adaptable line 01-698 (male parent) selected from Jimian No. 8, Kuaiyu 66 was crossed, selected and increased generation in greenhouse, combining with field selection, 3 generations per year cotton breeding technique and excellent plant type selection method for breach. Through adding generations in greenhouse, selling homozygous and field identification and selection, the new transgenic variety concentrated the good traits of high and stable yield, high efficiency and wide suitable, the lint yield, prefrost lint yield of the variety were respectively 1 518 kg/hm2 and 1 405.5 kg/hm2, and the pre-frost lint increased up to an extremely significant level in transgenic conventional cotton variety regional trials of South-central of Hebei Province in 2007 - 2009; In transgenic conventional cotton variety production test of south-central of Hebei Province in 2010, yields of 8 time points were all increased, lint yield, pre-frost lint yield were 1 401 kg/hm2 and 1 314 kg/hm2, increased by 7.7% and 10. 5% respectively comparing to control Jimian 958, which were all the highest one among the tested lines. This breed was disease resistant ( high resistance to Fusarium wilt, resistance to Verticillium dahli strength was 28.3 ae ), fiber quality comprehensive ( body length was 29 mm, uniformity was 84.9%, specific cN/tex, micronaire value was 5.3), management cheaper, comprehensive performance prominent.
