| 摘 要： | 对8个烤烟亲本及其配制的28个杂交组合的叶片性状进行了遗传分析。结果表明：（1）杂交组合叶数性状的平均值与其双亲平均值呈显著正相关关系，在一定程度上可用双亲均值估计F1群体叶数性状值。（2）烤烟叶数性状主要受加性效应控制，腰叶长、腰叶宽和叶面积主要受显性效应控制。（3）亲本P2（K326），P3（云烟87）和P1（G80）的叶数加性效应值较高，P8（红花大金元）的腰叶长、腰叶宽和叶面积状表现出较高的加性效应，因而可作为亲本来改良这些性状。P6（净叶黄）在叶数、腰叶宽和叶面积3个性状中，均表现出较高的负向加性效应，表明该品种不宜作为这些性状改良的亲本。 |

| Abstract: | The leaf characters were analyzed for 8 flue cured tobacco varieties and their 28 F1 crosses.The results indicated that（1）The correlation coefficient between average of crosses’ number of leaves and parents average was significant at 5％ probability level，to a certain extent，it could predicate the number of leaves for F1 crosses by using parents average.（2）Number of leaves was mainly controlled by additive effects，dominance effects were the major genetic component for length of leaves，width of leaves and area of leaves.（3）The additive effects values of number of leaves were higher for Parents P2（K326），P3（Yunyan 87）and P1（G80）.The additive effects values of P8（Honghuadajinyuan）were higher for length of leaves，width of leaves and area of leaves.Improvement of these characters could make use of these varieties.The number of leaves，width of leaves and area of leaves of P8（Jingyehuang）had highly negative additive effects，it showed that the variety was unfit for improving these characters. |
