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、脱落率和纤维品质无明显不良效应。 Two pairs of near-isogenic lines with good near-isogenicity were tested to study the effects of narrow-bramble leaf genes on 19 traits of yield and quality. The results showed that, compared with the normal bryophyte near isogenic lines, the narrow bracty bract grew vigorously and grew well. The plants were tall, boll light, small in size, low in finger, more in fruit nodes, Significance is related to genetic background and test site. The narrow brachial leaf genes have no obvious adverse effect on cotton yield, lint percentage, number of fruit branch per plant, shedding rate and fiber quality.
