【摘要】 采用人工去雄方法,利用抗蚜×感蚜、耐蚜×感蚜、感蚜×感蚜等组合的杂交后代和回交后代,对高粱品种抗蚜的遗传规律进行研究。结果表明,高粱的抗蚜基因对感蚜基因表现显性,受主效单基因控制。更多还原

【Abstract】 The inherence of sorghum resistance to aphid was studied using crossing and backcrossing of different combination, such as: aphid resistant variety × aphid susceptible variety, aphid tolerant variety × aphid susceptible variety and aphid susceptible variety × aphid susceptible variety. The results showed that the aphid resistant character of sorghum is dominant and controlled by a single gene.更多还原
