摘　　要：对通辽地区不同时期育成并在生产上推广应用的9个蓖麻品种产量及产量构成因素与农艺性状的关系进行研究,试验结果表明:矮秆杂交种中aLmAB5/091078产量最高,为3289.97kg/hm2;高秆杂交种中通蓖9号产量最高,为2526.03kg/hm2;高秆常规种中哲蓖4号产量最高,为1877.90kg/hm2.蓖麻产量构成因素为:株数、单株蒴果数、每果籽粒数、百粒重;蓖麻单株产量构成因素为:蒴果数、单果粒数、百粒重.经通径分析,蓖麻单株产量性状中,单株粒数对单株产量的直接贡献最大,主茎果穗数对单株产量的直接贡献次之.Researching the different periods of incubation and promote application related to Tongliao regional of 9 castor varieties yield, yield components and agronomic traits. The experiment results show that among all castor dwarf hybrids, aLmAB5/091078 produced the highest yield which is 3289.97kg/hm^2. Among all tall castor hybrids, the Tongbi 9produced the highest yield which is 2526.03kg/hm^2, Zhebi 4 produced the highest yield which is 1877.90kg/hm^2 among castor conventional seed. There are 4 factors which affect Castor yield： plants number, capsules number, grains number per capsules and hundred grains weight. There are 3 factors which affect yield per castor： capsules number, grains number per capsules, and hundred grains weight. Through analysis of castor＇s path, the number of grains per capsules provide greatest direct contribution among the factors of yield per castor; the second place is followed by the number of capsules.
