Some quantitative characteristics of pepper fruits – length, diameter, weight, thickness of pericarp and number of celled (lobed) in direct and reciprocal crosses between pepper cultivars Kapia 1300 and Doux D' Espagne and between Doux Marconi San Semences and Kalinkov 800/7 were investigated. The coefficient of variation, phenotypic domination, inheritance in F2 generation and influence of the above-mentioned traits on the fruit weight were determined by the Path-coefficient analysis. Significant effect of the direction of the cross to the type of inheritance was established. The weight of fruit, diameter of fruit and thickness of pericarp were inherited superdominantly. The fruit weight, length and diameter can be used for successful selection in F2 generation, because of the high coefficient of inheritance. The highest direct (or indirect) effect of the fruit length and thickness of pericarp was found on the fruit weight.
