设置“高油×高油”、“中油×高油”和“中油×低油”3种组合类型,对各组合类型后代品系油分含量进行分析测定,研究了大豆不同亲本组合对后代品系油分含量的影响。结果表明,大豆杂交组合亲本油分含量通过杂交后代群体对后代品系有显著影响,亲本油分含量与组合后代品系油分含量呈正相关。不同油分含量的大豆杂交亲本组合类型对后代品系油分含量有显著影响,同时受人为选择方式的影响。试验明确了大豆杂交后代群体油分含量的遗传过程及选择作用对后代品系油分含量的影响,为大豆品质育种实践提供参考。
The oil composition of the three offspring of different combination types was analyzed and determined. The effects of the different parents of soybean Effect of Combination on Oil Content in Offspring. The results showed that the oil content of the parental hybrids had a significant effect on the progeny lines through the hybrid progeny population. The parental oil content was positively correlated with the oil content of the progeny lines. The type of parental combinations of soybean with different oil content had a significant effect on the oil content of the progenies, and was influenced by the man-made selection method at the same time. The experiment defined the genetic process and selection effect of oil content in the offspring of offspring of soybean to influence the oil content of the progenies, which provided a reference for the practice of soybean quality breeding.
