摘　　要：以安徽省的13个茄子地方种质为试材，对12个植物性状的变异和性状间的相关进行了分析。结果表明（1）各性状变异系数由大到小依次为单株早期果数＞果形指数＞果实纵径＞单株总果数＞单果重＞果实横径＞开展度＞株高＞茎粗＞始花节位＞现蕾日数＞开花日数。（2）株高与始花节位、现蕾日数、开花日数分别是极显著成显著正相关，与单株早期果数、单株总果数、果形指数呈显著负相关。（3）单株早期果数和单株总果数分别与果实纵径、果形指数呈显著正相关。单果重与果实横径呈极显著正相关，与果形指数呈显著负相关。果实横径与果实纵径是极显著负相关。The variability and correlation analyses of 12 characters of native eggplants were studied. The results showed that (1) The variation coefficient of 12 characters were in order: F1>F6>F5>F2>F3>F4>P2>P1>P3>P3>P1>P2, (2) The plant height correlated with the node where the first flower was located, the days from the sowing date to the first flower oc-curing, and the days from the sowing date to the first flower blooming,was very significant or significant. It had significally neyutive correlations with the fruit-number per plant in early period, total fruit-number per plant, and the ratio of the length to the width of fruits. (3)The fruit-number per plant in early period and total fruit number per plant had significant correla-tions with the fruit length, and the ratio of the length to the width of fruits, respectively. The weight per fruit had a very sig-nificant correlation with the width of fruits, and a negative correlation with the ratio of the length to the width of fruits. The width of fruits had a negative correlation with the length of fruits very significantly.
