夏谷杂种一代与双亲的抗锈性关系研究

Study on Rust—resistant Relation between Hybrid F_1 and It's Parents in Summer Millet

通过分析732个夏谷杂种一代与其双亲的抗锈性关系,结果表明夏谷杂种一代的锈病发生偏感锈亲本,特别偏向于感锈的母本。在选配组合时应选用抗锈的亲本,选育抗锈的雄性不育系对选育抗病高产杂交种非常重要。

The study indicates that the summer millet hybrid's rust-resistant inchnes to it's susceptible Parent,especially to susceptible female parent,we should select rust-resistant variety as the parents to the hybrid.It is very important for high Yield hybrid to breed of rust-resistant male sterile strain.
