本文根据1984～1985年,我院自选的25个蚕豆新品系的田间试验结果,对几个与产量有关的性状进行了分析。遗传相关分析表明,百粒重、单株粒数和荚果长与蚕豆产量关系密切,其遗传相关系数值分别为—0.822,0.790和0.798。单株粒数在遗传通径分析中表现出对产量有特别重要的直接影响。百粒重和荚果长通过单株粒数对于产量的间接影响也很大。研究结果对于蚕豆育种过程中亲本选配和后代选择有一定的参考价值。 Based on the field test results of 25 faba bean lines selected from 1984 to 1985 in our hospital, several yield traits were analyzed. Genetic correlation analysis showed that the grain weight per plant, grain number per plant and pod length were closely related to the yield of faba bean. The genetic correlation coefficients were -0.822, 0.790 and 0.798 respectively. The grain number per plant shows a particularly important direct impact on yield in genetic path analysis. The indirect effects of 100-grain weight and pod length through grain number per plant are also significant. The results of this study have certain reference value for the selection of parents and offspring in the process of broad bean breeding.
