最近高氢氰酸潜势的高粱和低氢氰酸潜势的苏丹草杂交的幼苗氢氰酸潜势的遗传研究结果表明,母本或亲本对 F_1代及回交后代粒重和幼苗氢氰酸潜势的影响(Lamb 等,1987)。然而在 F_2代没发现这种相应作用的证据,表明未包括细胞质遗传。发现对所有试材一起分析,粒重和幼苗氢氰酸含量之间呈显著的正相关(r=0.85~**,显著平准P≤0.01),试材为所有亲本品系(r=0.82~**)、所有 F_1群体
The recent genetic studies on the potential of hydrocyanic acid in seedlings of sorghum with low potential for hydrocyanic acid and sudangrass potential for low potential hydrocyanic acid showed that the maternal or parental effects on F_1 generation, The impact of acid potential (Lamb et al., 1987). However, no evidence of this corresponding effect was found in the F_2 generation, indicating that cytoplasmic inheritance was not included. The results showed that there was a significant positive correlation between the grain weight and the content of hydrocyanic acid in the seedlings (r = 0.85 ~ **, P <0.01), and all the parental lines (r = 0.82 ~ **), all F_1 groups
