摘 要 ：采用经测验具有良好近等基因性的两对近等基因系，研究窄卷苞叶基因对产量、品质共19个性状的影响。结果表明，与正常苞叶近等基因系比较，窄卷苞叶系营养生长旺盛，植株高大，铃轻、子小、衣指低，果节多、结铃多，不易早衰，但两者差异显著性与遗传背景和试验地点有关。窄卷苞叶基因对棉花产量、衣分、单株果枝数，脱落率和

Abstract:Four near-isogenic lines of upland cotton, Gossypium hirsutum L., which carried frego bract(fg) vs. its normal-bract equivalents(Fg) in two backgrounds, were grown in replicated experiments in two places in Hubei. 19 agronomic properties were studied. Results showed that the frego near-isolines had
