Abstract
This study was conducted at Barrage Horticulture El-Kanater, Kaluobia Agricultural. Research Station. During the period 2002·2004 to study the inheritance of some bean varieties. Four bean cultivars viz., Bronco. Poulesta. Tema and Deoul were used in this study. Production of different generation, i. e. Parents. Flo F,r. and F2 population were estimated. The population were evaluated for plant height. number of days to Oowering, green pods ylelo/plant. number of pods/plant. pod weight and pod length. Generally, all degrees of dominance (no, partial. complete and overdominance) were estimated. Average degree of heterosis for all characters. minimum number of genes, and broad sence heretability (BSH) were estimated. Tl1e different types of dominance were observed in many populations, such as overdominance for the better parents were observed in some traits, i. e. plant height. pod weight, pod yield and number of pod/plant. On the contrary overdominance towards the low parents was observed in number of days to Oowering. Partial dominance for the better parents were showed in pod weight and number of pod/plant. On the other hand partial dominance towards the low parent observed in characters such as plant height, number cf days to flowering. pod weight. and green pod yield/plant. Complete dominance were showed in pod weight and number of pod/plant. No dominance were obtained in plant height, number of pod/plant and green yield/plant. Positive heterosis were showed in most characters as plant height, number of days to flowering, pod weight. number of pod/plant and green pod yield/plant. Also negative heterosis was in some characters for some crosses. Minimum number of genes were estimated for all characters it is ranged from one pair to three pairs. BSH were estimated in all characters it is ranged from 40.70 to 93.40.
