【摘要】 对19个抗虫亲本配置的18个杂交组合的F₂与F₁进行了试验比较。结果表明,杂交F₂与F₁相比,子棉减产8.90%,皮棉减产9.11%;在产量构成因素中,F₂的单株结铃数相对较少;除麦克隆值以外,纤维品质的其它指标差别不明显。更多还原

【Abstract】 Hybrid F₂ and F₁ of 18 crosses made from 19 bollworm-resistant cotton parents had been tested.Compared with F₁,F₂ showed the average results of 8.9%decrease in seed cotton yield and 9.11%decrease in lint yield.Among the yield components,bolls per plant of F₂ apparently reduced. Except micronaire value,the other elements of fiber quality had very little differences between F₂ and F₁.更多还原
