以15个棉花品种为试材,在全程干旱胁迫条件下,对品种主要遗传性状与皮棉产量之间的关系进行了相关分析和通径分析。结果表明：全程干旱胁迫条件下,皮棉产量与单株铃数和株高呈极显著正相关,与衣分呈显著正相关;与铃重和单株铃数呈显著负相关。单株铃数与皮棉产量的直接通径系数最高,是干旱胁迫下皮棉产量最重要的直接影响因子;株高通过其他性状对皮棉产量的间接通径系数均为正值,表明株高对抗旱品种皮棉产量的综合贡献较大。

The relationship between main genetic characters and lint yield of 15 cotton varieties in the whole growth period was studied by the way of correlation and path analysis. The results showed that the lint yield very significantly positively correlated with the boll number per plant and plant height, significantly positively correlated with lint percent, while significantly negatively correlated with boll weight and boll number per plant. The direct path coefficient between boll number per plant and lint yield was the highest. The boll number per plant was the decisive and the most contributive factor to the lint yield. Plant height impacted the lint yield through other characters, and the indirect path coefficient was positive, indicating that plant height was the important factor influencing the lint yield of drought resistant varieties.
