[ Objective] To give some refernence informations for using Xinluzao 33 better. [ Method] 16 main characters of Xinluzao 33 in 2nd , 5th, 6th , 7th , 8th Agricultural Divisions in Xinjiang, and Hexi corridor in Cansu from 2004 to 2008 have been comparatively analyzed . [ Result] Xinluzao 33 have been cumulatively planted by 101 946 .619 hm2 in 6 cotton regions for 5 years . The planting area in 2007 (50432.86hm2) and 8th Agricultural Division (35 039.96 hm2) were the greatest, The plant height, first intemode position, number of fruit - bearing shoot, and boll number per plant of Xinluzao 33 had extremely significant differences among 6 cotton regions, and the firsl inlemode was higher, boll was heavy, and lint percentage had Significant differences. The other 9 characters had no significant differences . The seed cotton yield and lint yield showed continual increase for 5 years, and there was significant difference (extremely significant difference) between some years. The other 14 characters had no significant difference. [Conclusion] The main characters of Xinluzao 33 had higher stability. Cultivation measures and management level increasing continuously had developed high - yield potential of Xinluzao 33, and it may have more potential of increasingyield .%[目的]为更好地开发利用新陆早33号提供参考信息.[方法]对新陆早33号于2004-2008年在农二师、农五师、农六师、农七师、农八师、甘肃河西走廊的16个主要性状进行比较分析.[结果]5a间新陆早33号在6个棉区累计种植101 946.619 hm2;其中2007年(50 432.86 hm2)和农八师(35 039.96 hm2)的种植面积分别最大.6个棉区间除了株高、始节位、果枝数、单株铃数存在极显著差异,始节高、单铃重、衣分存在显著差异外;其它9个性状的差异均不显著.5a间籽棉和皮棉产量呈现显著连续上升的线性趋势,并且有些年份间的差异显著(极显著);其它14个性状的差异均不显著.[结论]新陆早33号的主要性状具有较高的稳定性;栽培措施的不断完善和管理水平的不断提高逐步挖掘出了其高产潜力;该品种可能还有再增产的潜力.
