低酚棉的丰产潜力及丰产性结构的分析

Analysis of Potential and Structure in Bringing about High Yield of Glandless Cotton

选用８０年代末具有代表性的低酚棉丰产品种（无色素腺体）、有酚棉丰产品种（有色素腺体）以及低酚棉原始品种（无色素腺体源），就产量水平、熟性、以及产量构成因素间的差异进行了比较试验和分析。结果表明，无色素除体源比有色素腺体品种的产量低且晚熟，但新育成的无色素腺体品种与有色素腺体品种的产量水平及熟性差异不显著。

This study compared and analysed yield, maturity and yield,components between high-yielding glandless, high-yielding gland and primitive glandless cotton strains. The results showed that the primitive glanless cotton was lower in yield and later in maturity than gland cotton, but the difference in yield and maturity between current improved glandless and gland cottons was not significant.
