This study was carried out at El-Kanater El-Khayria Vegetable Rsearch Farm, Kalubia Governorate, Egypt. During the period from 2008  to 2010. Four pea cvs., viz., Master B, Samroula, Waver Top and Kiados were used in this study. Crosses between these cvs were done and F_1, F₁r and F₂ seeds were produced and evaluated to study the inheritance of some economic characters. Absence of maternal effect was noticed for all characters in all crosses. Different types of dominance were found in different crosses for the studied characters as over dominance which was found for all characters except for the characters pod length and number of seeds/pod, meanwhile, partial dominance were detected in some hybrids for studied characters. Positive heterosis values estimated were 1.36 % - 28.10 %, 2.75 % - 30.97 %, 0.60 % - 3.26 %, 10.63 % - 22.83 and 2.78 % – 4.84 % for plant height, total green pods yield/plant, pod length, number of pods/plant and number of seeds/pod, respectively. While negative heterosis estimated was from -15.84 % for plant height and -5.48 % for number of seeds/pod.   Minimum number of gene pairs estimated was 1-2, 1-9, 1-12, 1-4 and 1-7 for plant height, total green pods yield/plant, pod length, number of pods/plant and number of seeds/pod, respectively. BSH estimates for previously listed characters were, respectively, 70.66 % - 89.89 %, 32.56 % - 67.60 %, 38.58 % - 77.85 %, 27.39 % - 68.42 % and 50.00 %  - 67.88 % for this characters. In general, some promising F₂ plants could be selected to start a breeding program for producing a new pea cultivar.
