Taking twenty two hybrid cotton F\-1'and F\-2'as the experimental material along with two standard vavieties F\-2,Xinluzao No.1 and xinluzao No.7,as the double checks,the comparative experiment was caried out in 1997.During the experiment,through observing in field,examination in laboratory,fiber qualities analyses with HVI900 and analysis of variance,three better Combinations have selected in which PA 61R 9 was the best combination,following by ZhongA 61R 9 and 2A ZhongR 16 for lint yield.All these three combinations showed high lint cotton yield and superior fiber qualities.Therefore,these better combinations can be used as the main material in the following studies to continue studying their agronomic traits and fiber qualities.\;
