摘　　要：通过甘兰型油菜新品系(种)的主要经济性状对单株产量影响进行相关分析。结果表明,五个性状对单株产量均呈正相关,相关系数大小依次为有效角果数,每角果粒数,千粒重,株高,有效分枝数。进而进行通径分析,分析各性状对单株产量的直接作用和间接作用,结果表明,每角果粒数,有效角果数对单株产量的直接作用大,其次为千粒重,有效分枝数直接作用小,株高为直接弱负效应。千粒重,有效分枝数,株高对单株产量的间接作用较大。Influences of sweet cole's major economic properties on the yield of single—plant were analyzed in this paper.Results showed that five properties had positive relations with the yields of single—plants, namely,with indexes from high to low,the number of effective pods,the number of grains in each pod, the weight of every 1000 grains,the height of plant,and the number of effective tillering.Then,ali— round analyses were conducted to study the direct and indirect effects of each property on single plants. The number of grains in each pod and the number of effective pods proved to have the greatest direct ef- fect,next are the weight of every 1000 grains,the number of effective tillering and the height of plants. The weight of every 1000 grains,the number of effective tillering and the height of plants have greater di- rect effect on the yield of single plant.
