以19个蓖麻品种为材料,对蓖麻种子含油量与主要数量性状进行相关及通径分析。结果表明:含油量除与生育期呈显著负相关外,与其它主要农艺性状间相关均不显著,而与籽粒自身的性状之间有着显著的相关,其中容重对籽粒含油量的直接通径系数最大,应在亲本选配和后代选择过程中作为一个主要因素考虑。在提高产量的同时注重选择籽粒容重大、籽粒短、生育期适中的类型对提高含油量有积极的作用。
Nineteen castor varieties were used as materials to analyze the correlation between the oil content of castor seeds and the major quantitative traits. The results showed that there was a significant correlation between the oil content and the main agronomic traits, except for the significant negative correlation with the growth stage, but significant correlations with grain traits. The direct path coefficient The maximum should be considered as a major factor in parental selection and selection of offspring. At the same time to increase the yield, it should pay attention to choose the type of large grain size, short grain and moderate growth period, which has a positive effect on increasing oil content.
